For speed detection, knob control, and rotary apps, the AEAT-601B incremental magnetic encoder provides angular detection over a 360° rotation. The device employs a three-channel output, enabling an index channel for each rotation. In addition to employing a closed-loop feedback system, it offers multiple resolution options in the realm of 256 cycles per revolution. Other features include contactless sensing, an operating temperature range from -40°C to +125°C, and operation from a single 5V supply. Pricing for the AEAT-601B incremental magnetic encoder is $18.50 each/1,000. AVAGO TECHNOLOGIES, San Jose, CA. (800) 235-0312.
