From cost-aware standard types through to extremely robust heavy-duty products, HENGSTLER can supply the right incremental rotary encoder for every application.
With optical incremental rotary encoders, a line-coded disc made of metal, plastic or glass and mounted on a rotary bearing interrupts a beam of light from a light-emitting diode, the number of lines determines the resolution, i.e. the number of measured points in one revolution.
The interruptions of the light beam are sensed by the receptor element and electronically processed, the information is then made available as a rectangular signal at the encoder output. HENGSTLER can provide rotary encoders with up to 10,000 pulses per revolution.
