Encoders

Incremental Encoders, Absolute Encoders, Encoder Kits and Accessories

Encoders are used in all types of motion sensing applications, including machine tooling, semiconductor positioning and multi-axis positioning. All Koyo 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.

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
