As we celebrate Grayhill's 80th anniversary, we are highlighting the flagship products that changed the course of our company. Among these groundbreaking innovations, the optical encoder stands as a pioneering product introduced in the late 1980s. 

One of the most significant advantages of optical encoders, such as our first iteration, the 61B, is the utilization of non-contact switching technology. Instead of relying on physical contact between components, optical encoders use light to detect and encode rotational movements. This non-contact approach results in several key benefits. Optical encoders boast an exceptionally long operational life because there is no physical wear and tear from contact. This is a critical advantage in applications where reliability and longevity are essential. Non-contact technology also allows for extremely precise encoding, making optical encoders the go-to choice in situations where accuracy is mission-critical, such as in medical, robotic, and aerospace equipment. Optical encoders also provide exceptional haptics so that rotations can be felt through heavy gloves and rugged conditions. The versatility of optical encoders cannot be overstated.

Grayhill understands that each industry and application has unique requirements. We meet those standards by offering a high degree of customization with our optical encoders. Whether you require specific detents (clicks) and tactile feel, shaft length and flats, multiple termination and cabling options, and custom mounting, Grayhill can tailor optical encoders to suit your exact needs.
