Grayhill’s high-resolution, 5-pin 61R Machine Rotary Encoders provide excellent tactile feedback to the user, making them a reliable choice for various applications. They feature debris-resistant Hall-effect sensor technology and are available in multiple cycle options, including 25, 32, 50, 64, 100, 128, and 256 cycles per revolution. Additionally, users can choose between sealed versions for more demanding environments or standard models. With a sturdy construction and options for cable or pin configurations, these rugged encoders are designed to withstand rigorous use and boast an impressive operational life of up to 10 million rotational cycles. The greatest advantage of optical encoders lies in their non-contact switching technology, which contributes to an exceptionally high operational life. While the specific end product may vary, optical encoders are commonly utilized in applications that measure speed, distance, and rotational angle. Their design and functionality make them suitable for a wide range of industries where precision and durability are essential.
