Rotary encoders use an internal coded disc and a sensing head to sense the rotary position, useful in motion sensing applications such as machine tooling and multi-axis positioning. Incremental encoders output pulses that track relative position; absolute encoders output a value, retained through a power cycle.

Encoders
Category Selection
Incremental Encoders, Absolute Encoders, Encoder Kits and Accessories
Encoders Overview
Encoders are used in all types of motion sensing applications, including machine tooling, semiconductor positioning and multi-axis positioning. All encoders feature a reinforced aluminum diecast casing and come equipped with a two-meter cable or MS connector. All kit encoders (for stepper motors) are ready-to-mount, with hardware and shaft adapters included.
Use incremental encoders with our PLC high-speed input modules for accurate position monitoring. Absolute encoders provide immediate position information on power-up (without a homing sequence) and can be wired to standard PLC DC input cards. Cables, mounting brackets and flexible couplings are also available.
Availability-Price-Quality
- All our encoders are typically in stock and available for immediate shipment
- As with all our product lines, our prices are often well below the list prices of traditional automation suppliers
- All encoders carry a 1-year warranty and have a 30-day money-back guarantee

Light Duty Incremental Encoders (Quadrature)
A light-duty encoder is a cost-effective encoder for applications with light shaft loading. These encoders are perfect for industrial applications with good mounting conditions and flexible shaft couplings.
- Resolution available from 100 pulses per revolution to 2500 pulses per revolution
- 6mm solid shaft or 8mm hollow shaft
- Small body - 38mm or 40mm diameter
- Dust proof (IP50) and water resistant (IP65) ratings
- Open collector or line driver output
- Up to 200 kHz maximum response frequency
- Two-meter cable with tinned ends
Medium Duty Incremental Encoders (Quadrature)
Medium-duty encoders are the most popular encoders, offering the greatest flexibility of choice with high quality, all for a very low price.
- Incremental resolution available from 3 pulses per revolution to 5000 pulses per revolution
- 8mm or 3/8-in solid shaft, 8mm hollow shaft
- Medium body: 2 inch or 50mm diameter
- Dust proof (IP50) or splash proof (IP65) ratings
- Line driver or totem-pole output
- Up to 200 kHz response frequency
- Two-meter cable with tinned ends or MS connector
Heavy Duty Incremental Encoders (Quadrature)
A heavy-duty encoder is the most rugged encoder you can buy. Top-of-the-line bearings help maintain a service life of 12 billion revolutions and allow significant loads on the shaft.
- Incremental operation from 30 pulses/revolution to 5000 pulses/revolution
- 10mm solid shaft
- Large body: 3 inch or 78mm diameter
- Splash proof (IP65) rating
- Totem-pole output
- Up to 100 kHz response frequency
- Two-meter cable with tinned ends
Medium Duty Absolute Encoders
(Gray Code)
Absolute encoders use gray code (a version of binary where the outputs only change state one bit at a time) to describe each position, so position data is not lost when power is cycled AND the response frequency is slower for a given resolution.
- Absolute resolution available from 32 to 2048 pulses per revolution
- 8mm solid shafts
- Small body with 50mm diameter
- Splash proof (IP65) rating
- Resolution ranges from 5-bit to 11-bit gray code output
- Up to 20 kHz response frequency
- Two-meter cable with tinned ends
Modular Kit Encoders for Step Motors
SureStep® modular encoders for stepper motors and motor/drives are traditional optical encoders with convenient bolt-on options (dual shaft SureStep motors have the proper mounting holes predrilled). Replacement modular encoders for select SureStep® integrated motor/drives are also available.
Extremely rugged AMT series encoders from CUI Devices® use state-of-the-art capacitive technology and are available in fixed resolution or configurable models. Configurable models use either DIP switches or the free AMT Viewpoint configuration software to set the resolution (software also allows alignment of the Z-pulse)
- Capacitive or optical encoder technology
- Configurable and fixed resolution models
- Compatible with all dual-shaft stepper motors in various NEMA sizes
- Compatible with select integrated motor/drives
- Quadrature output signals
- Single-ended (totem-pole) and line driver output models
- FREE downloadable configuration software for appropriate models
Encoder Accessories
Simplify your installation with ready-to-use couplings, mounting brackets / flanges, and wiring cables / connectors. Couplings provide a connection between encoders and solid shafts. We offer fiberglass and aluminum couplings for metric, S.A.E. and metric-to-S.A.E. applications. Signal & configuration cables and connectors are also available where optional or required.
- Encoder couplings available for all solid shaft encoders
- Encoder mounting brackets and flanges
- Servo mount clamp for TRD-MX series encoders
- Encoder cables and connectors
