PRODUCT GLOSSARY

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.
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
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.
Complements

Also known as complementary outputs. To ensure that signal noise does not cause errors between the encoder and the controller, many encoders output signals that are driven in exactly opposite directions: when A goes high, A NOT goes low (, ); when A goes low, A NOT goes high. Controllers which see a transition in A, but not in the A NOT signal, would report a quadrature error.
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.
Hollow Shaft

Hollow Shaft encoders mount by passing the shaft of the motor into or through the encoder. Hollow shaft encoders are easy to mount and replace but are vulnerable to damage. Also, the weight of the encoder must be considered for small motor shafts < 0.75" diameter. Avtron offers a full range of hollow shaft encoders, including: AV685, HS25A, HS35A, HS35M, M3, M4, M6, M7, XP45.
Line Driver

The chip or output circuit that forms the electrical pulses output from the encoder. Avtron has extremely advanced line driver technology to prevent damage from overvoltage and short circuits. Avtron offers optional high-power line drivers to perm it Avtron encoder signals to travel farther down long wires to remote controller/drive locations without the need for repeaters or amplifiers.
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.
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.
Mill Duty

Mill Duty encoders are sturdier than light mill duty and can withstand more shock, vibration, and bearing loads. Mill duty encoders must be protected from temperature cycling and contaminants.
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 Errors

Optical Errors include false pulses, missed pulses, and quadrature errors that are generated when there is any type of contamination (dirt, oil, water, condensation) on the optical disk.
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.
Quadrature

To determine which direction an encoder is revolving, encoders output quadrature signals: two streams of pulses, A & B, generated at 90� timing angles. (Also called A Quad B) A leading B indicates rotation in one direction; B leading A indicat es the encoder is rotating in the opposite direction. Example: �A leads B with clockwise rotation as viewed from the encoder face on an HS45 encoder." Many encoders with quadrature outputs also have complementary outputs: A NOT and B NOT signals.
Quadrature Errors

Failures of the encoder to generate properly formatted quadrature signals. Most typically, these are failures to create the proper 90� signal separation between the A and B channel outputs, with a less than perfect stream of square waves. Most con trollers, when presented with a quadrature error, will report a drive fault or encoder fault and then shut down.
Resolution

Resolution describes how many individual slices or positions can be reported by an incremental or absolute encoder. For incremental encoders the number of PPR (pulses per revolution) expresses resolution; for absolute encoders, PPR, or counts per turn or bits of resolution may be listed.
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.

Sensor Crash

When the rotating disk in an encoder contacts the sensor (optical or magnetic/magnetoresistive), it damages or destroys the sensor. Sensor crashes can be caused by excessive vibration, shaft runout, or alignment problems in encoder mounting. Avtro n encoders feature Wide-Gap technology to eliminate sensor crashes.
T.I.R.

Total Indicated Runout. This is a measurement of how much a shaft wobbles with each revolution (shaft runout).
Torque Arm

A type of anti-rotation arm used to mount hollow shaft encoders to large frame motors. It features a threaded rod for adjustable radius.
Wide-Gap Technology

Avtron encoders use special optical sensors and magnetoresistive sensors, combined with proprietary circuit designs to allow the sensor to be located much farther from the magnetic rotor or optical disk. This eliminates sensor crashes and makes mo unting easy and forgiving of mechanical variation.
