A range of optical encoders from Grayhill are available at EAO. The three devices in the 62xG range of optical encoders use a patented optical switching technology that delivers a 2-bit digital quadrature output and are capable of over 1 million switching cycles, which together with a rugged enclosed metal body and a metal shaft ensures that the new optical encoders provide a more durable and more cost effective alternative to conventional mechanical encoders.

The 62AG Series productsoffers 16, 20, 24 or 32 pulses per revolution and the choice of pinned or flying lead connections in various standard lengths. Other options include high, low or no detent torque and a pushbutton.

With a low 7.5mm back panel depth requirement Grayhill has designed the 62SG Series of optical encoders specifically for space critical applications. The devices are available with high, medium and low detent torque options.

In addition to all the features of the 62AG Series, the 62NG Series encoders offer a non-turn pushbutton within the encoder shaft that ensures that any legend printed on the cap always remains upright when the encoder shaft is turned.
