Haydon Switch & Instrument’s size 11 hybrid linear actuators are now available with encoder feedback. According to the company’s press release, the compact optical incremental encoder design is available with two channel quadrature TTL squarewave outputs. An optional index (3rd channel) output is also available for many resolutions. The encoder is offered in resolutions ranging from 200-1,024 cycles per revolution (CPR) or 800-4,096 pulses per revolution (PPR). The encoder operating temperatures are -40-100 degrees C. Encoders are designed for both high and low volume motion control applications. The internal monolithic electronic module converts the real-time position, speed, and direction into TTL compatible outputs. The encoder module incorporates a lensed LED light source and monolithic photodetector array with signal shaping electronics to produce the two channel bounceless TTL outputs. These hybrid linear actuators are available in a wide variety of resolutions ranging from 0.000125"(.003175 mm) per step to 0.002" (.0508 mm) per step and deliver thrusts of up to 25 lbs. Applications requiring precise positioning and rapid motion are best suited for this motor.
