Description

Avtron HS4 encoders are setting THE industry standard for incremental quadrature hollow shaft rotary encoders. This versatile lineup fits the same mounting patterns on all motors and machines as competitor units, but that’s where the similarities end. We've incorporated Avtron magnetic sensing technology to this affordable set of encoders! This makes HS4 more resistant to dust, dirt, oil and other liquids that make ordinary optical encoders fail.

Our Wide-Gap technology provides for 10-20X larger air gap between sensor and rotor than ordinary optical encoder designs. Consider the resistance to vibration when you compare our 0.060” air gap to the typical 0.004” clearance from the thin, often flexible, optical disk spinning at full motor speeds. Our high-accuracy magnetic sensors provide high quality quadrature signals for precise velocity and position control with the durability of magnetic sensing technology.

Our magnetic HS4 encoders are setting a new standard for quality, durability, and performance. Select an Avtron HS4 today!

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. For more information on quadrature- Wikipedia: http://en.wikipedia.org/wiki/Quadrature_phase
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.
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 digital message, a set of parallel outputs, or analog values.
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 encoders.
Light Mill Duty

Light Mill Duty encoders are designed for industrial applications but must be protected from contamination, temperature cycling, and physical force, including shock, vibration, and bearing loads. Examples include AV20, AV25, HS25A, and HS35A models.
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 permit 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 encoder. 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" in Europe.
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 indicates 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.
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 incremental velocity feedback. Avtron rotary encoders are designed and built to be far more reliable than ordinary rotary encoders. Avtron encoder white papers on our blog provide more details of how and why Avtron rotary encoders are more reliable.
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 mounting easy and forgiving of mechanical variation.
Wiegand wire

Wiegand wires generate a pulse of electricity in a coil as a magnet passes near the wire. Wiegand wires are used in Avtron absolute magnetic encoders to self-power the multi-turn counting engine, so even if the encoder has no power when turned, the absolute encoder correctly reports the number of turns and position. This allows Avtron to eliminate the glass disks and gears that cause failures in other absolute encoders.
