Description

XP5 SMARTSafe™ sensors power the world's first explosion-proof encoder with removable electronics and no external barrier! They are cULus, ATEX, AEx & IECEx certified and offer incredibly reliable no-bearing construction! SMARTSafe XP5 sensors can be used in ATEX/IECEx, cUL, AEX, and UL gas hazardous environments.

Also available: no-bearing modular encoders (XPH8), as well as intrinsically safe models (XR5, XR12, XR56A, XR125, XR485, XR685, XR850), and hollow shaft models (M6C).

For Level 1 applications requiring ATEX/IECEx Zone 1 or cULus Class I, Division 1, Groups C & D use the XP5 directly in your application with no barrier or isolator required.

Unlike the competition, Avtron SMARTSafe encoder systems are protected against short circuits, power-to-output wiring, and output-to-ground faults. XP5 features full diagnostics: it's easy to determine that signal quality is good, and that there are no wiring short-circuits.

Instead of mounting a tiny optical encoder with weak bearings on a wobbling stub shaft mount XP5 directly on your machine and install the rotor on your main application shaft. Top drives, draw works, coil tubing, paint lines...so many applications benefit from a more reliable no-bearing encoder. Vibration, shock, liquids, dust and dirt won't harm SMARTSafe XP5 encoders!

Eliminate the biggest cause of hazardous duty encoder failure--eliminate the bearings with XP5 hazardous duty encoder sensors.

PRODUCT GLOSSARY

A Quad B

A Quad B refers to the set of output quadrature signals from an incremental quadrature encoder to indicate speed and direction, including complements: A, A NOT, B, B NOT (, , , ). Most Avtron encoders offer A Quad B output at no extra cost.&n bsp;For more information on quadrature- Wikipedia: http://en.wikipedia.org/wiki/Quadrature_phase
ATEX

ATEX is a directive used worldwide for equipment, including encoders, to be used around or in explosive atmospheres. ATEX certified equipment is NOT necessarily interchangeable with US-based UL Class/Division or Class/Zone rated equipment, nor IEC Ex rated equipment. ATEX is an alternative and different system. Review our full line of Avtron Explosion Protected, ATEX certified encoders, including

Axial Shaft Movement

Motor shaft movement in or out, relative to the ends of the motor. Often motors that use roller or sleeve bearing construction have more axial shaft movement. Most Avtron modular encoders tolerate +/- 0.050" of axial movement maximum. Use hollow s haft encoders for high axial movement motor styles, such as MD motors. Most competitors� modular encoders tolerate much less axial movement than Avtron products.
Bearingless

These encoders use the bearings of the motor or machine, eliminating a huge source of failure in encoders. Also known as modular and sandwich encoders.
Contamination

Also known as contaminants, such as water, dirt, dust, oil, and other compounds which enter an encoder through seal failure and can cause optical errors. If the contamination is abrasive, it can also cause bearing failures in the encoder. Modular encoders are very resistant to contamination as they use magnetoresistive sensors and have no bearings.
Encoder

A device which indicates position and speed via a set of digital outputs. Incremental encoders output quadrature (A Quad B) signals, and may add a marker pulse once per revolution. Absolute encoders typically indicate position via a digi tal message, a set of parallel outputs, or analog values.
Explosion Protected

Also known as Flameproof, explosion protected equipment has additional protection/safety enhancements for use in explosive atmospheres. Explosion Protected devices maybe placed directly into hazardous areas within their nameplate rating. No additi onal equipment is required if installation instructions are followed properly. By comparison, Intrinsically Safe devices may require the use of additional, external protection/current limiting devices outside of the hazardous area. Avtron offers hollow sh

IR LED

Infra-Red Light Emitting Diode is the light source for an optical encoder.
Incremental Encoder

An encoder that produces pulses in proportion to distance moved or rotated. Incremental encoders can also have a marker pulse Z, Z NOT (, ) once per revolution to provide a position reference. Avtron produces a full range of incremental rotary enc oders.
Intrinsically Safe / Intrinsic Safety

Is a system designed to improve equipment safety by limiting spark energy values in equipment used in hazardous areas. Intrinsic Safety is a different system of protection than Explosion Proof or Flameproof. Many Explosion Proof and Flam eproof encoders can be replaced with Intrinsically Safe encoders, provided the installation instructions are followed correctly and the system is compliant with the approved installation drawing. Intrinsically safe Magnetic Encoder

Magnetic and magnetoresistive encoders typically use a magnetized rotor with north and south poles lined up around the perimeter of the disk. A magnetoresistive sensor detects the transitions, and these are the counts or pulses generated by the en coder. Magnetic encoders withstand dirt, dust, water, and temperature changes far better than optical encoders.
Magnetic Rotor

A magnetized disk with multiple north and south poles lined up around the perimeter of the disk. A magnetoresistive sensor detects the transitions and generates the pulses generated by the magnetic encoder.
Magnetoresistive Sensor

A sensor that detects the magnetic poles on an encoder's magnetic rotor and transforms them into pulses. Avtron magnetoresistive (MR) sensors use advanced technology to reject external magnetic signals such as brake solenoids and motor magnetic fi elds. MR sensors enable Avtron magnetic encoders to ignore dirt, oil, water, and other contaminants.
Marker Pulse

The Marker Pulse occurs once per revolution. The purpose of the marker pulse is to provide a repeatable home position location for positioning applications. The marker pulse is often abbreviated as "�Z" or "Z" in the USA and "C" or "N" i n Europe.
Modular Encoders

Modular Encoders mount to a machined C-face or flange adapter on the motor (drive or non-drive end). Modular encoders consist of a rotor that mounts on the shaft, and a stator that bolts to the motor frame. Modular encoders are very rugged, and Av tron encoders feature Wide-Gap sensors to avoid complex shimming or fitting to the motor. Modular C-face encoders are typically used on DC motors; but some AC motors, such as Rockwell�s RPM III AC and Marathon�s Blue and Black Max motors, have C-faces sta

Motor Shaft Currents

The high-speed switching of variable frequency drives that is used to control the speed of motors often produces current which flows from the motor shaft to ground, or from end-to-end of the motor. These current are highly destructive to both motor and encoder bearings. Preventing shaft current damage is essential. Most Avtron hollow shaft encoders include features to prevent motor shaft current damage. For more information: Optical Disk

An Optical Disk is typically a glass, metal, or plastic disk with fine lines or slots etched around the perimeter that interrupt the beam of light from the light source to an optical sensor. Optical disks can be quite fragile. Avtron uses only sha tterproof optical disks with Wide-Gap technology.
Optical Encoder

An Optical Encoder typically uses a light source shining through, or reflecting off, an optical disk with lines or slots that interrupt the beam of light to an optical sensor. Electronics count the interruptions of the beam and generate the encode r�s output pulses.
Optical Sensors

Optical Sensors are typically phototransistors or other light sensors which sense the light emitted by the light source, as interrupted by, or passed through, the optical disk.
PPR

Pulses Per Revolution. Most Avtron encoders output quadrature pulses, with four times as many lines as pulses. Often lines can be counted in the drive/speed controller for higher resolution applications.
Pulses

Pulses are also known as counts and are the low voltage output transitions which indicate movement of the encoder. Encoders are rated by resolution or PPR (pulses per revolution). Pulses are not the same as lines.
Rotary Encoder

A rotary encoder provides position and/or speed feedback information about a rotating shaft. Rotary encoders may be hollow shaft, no-bearing modular, coupled solid shaft style. They may provide absolute positioning information, or increm ental velocity feedback. Avtron rotary encoders are designed and built to be far more reliable than ordinary rotary encoders.

Rotor

The disk-shaped portion of the modular encoder that is mounted on the motor shaft. Avtron modular encoders use magnetic rotors.
UL Listed

UL Listed Avtron encoders can be directly applied to any hazardous duty application which requires Class and Division, Class and Zone or AEX certification. Note that UL Listing is a different system than ATEX or IECEx. Ensure the model y ou select has the UL listing which meets the application requirements.
