CTS offers 291 Series

CTS offers the 291 series, a precision, long-life compact, 12-mm-size optical encoder

The 291 Series from CTS allows versatility in design applications by providing highly reliable, precise digital output and long rotational life with a non-contacting design. This product provides flexibility for resolution, power consumption, operating temperatures, and use in multiple environments. The optional momentary switch provides additional functions such as menu selection for digital displays.

The 291 Series is ideal for many applications which include, but are not limited to, the following: medical equipment, laboratory equipment, communication, industrial, HVAC, transportation, security, and professional and consumer audio and home entertainment equipment.

This series is a high performance Optical Encoder which features long life, detailed digital signal output, small size and versatile construction. It is one of the smallest available optical encoders containing a 12mm profile. Available in this series are 6 and 8 PPR resolution, as well as 3M life cycles (with no detents) and 1M cycles (with detents-up to 32 available) Lower power consumption is given with 5VDC or 3.3VDC operating voltage.
