The S4T miniature optical shaft encoder is a non-contacting rotary to digital converter. The S4T contains an LED light source, monolithic photo detector and mylar disk. The S4T encoder is available with a shaft bushing or ball bearings for motion control applications, or with shaft torque designed to feel like a potentiometer for front-panel manual interfaces. The encoder converts real-time shaft angle, speed, and direction into TTL-compatible quadrature outputs without index. It operates from a single +5VDC supply.

Our S4T Miniature Optical Encoders Are Now Available at Higher Resolutions of 512 and 1,000 CPR

The perfect fit for motion control where space is limited.

We've got some great news about our smallest encoders. The S4T miniature optical encoders are now available at even higher resolutions than before! With two new CPRs of 512 and 1,000 we've successfully doubled the resolution while keeping the housing unchanged.

Utilizing state-of-the-art transmissive optical sensing technology, these newly announced resolutions now support applications requiring up to 4,000 pulses per revolution. This substantial increase in resolution was achieved without any compromise to package form factor, electrical characteristics or output signal robustness. The S4T line of encoders is available in both single-ended and differential signal outputs for applications where noise immunity is critical.
Where space is limited, the S4T miniature optical encoders are the perfect fit for motion control. Get details at: usdigital.com/S4T
