Absolute rotary encoder for motor feedback
842HR Allen Bradley

Bulletin 842HR Sine/Cosine is a 15-bit serial encoder for high performance digital servo drive systems that require absolute feedback for position control, and high resolution incremental feedback for speed control. This encoder provides commutation, speed regulation, and position control all in one device.
