Description

RAHS35M encoders were private-branded versions of the Avtron HS35M. HS35M replaces this model directly with no shaft modification and no connector changes.

For increased reliability, upgrade to the HS45--also fits the same shaft and same electrical connector with no modifications.

Check our cross reference page to update to HS35M or HS45.

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
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 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.
Industrial EPIC

The preferred encoder connector of most users in North America. It contains a full size terminal strip and, unlike the MS connector, requires no soldering for quick field connections. Avtron offers pin-for-pin exact replacements for competitors� m odels using industrial EPIC� style connectors. EPIC� is a registered trademark of the Lapp Group.
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.
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.
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.
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.
