Haydon Switch & Instrument (Waterbury, CT) released size 8 hybrid linear actuators with encoder feedback. Encoder resolutions range from 120 to 330 cycles per revolution, or 480 to 1,200 pulses per revolution; encoder operating temperatures are -10 to 85°C. The optical incremental encoder design is available with two-channel quadrature TTL squarewave outputs. The units are available in resolutions ranging from 0.00006 to 0.00157" per step, and deliver thrusts of up to 10 lbs.
