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.

The universally applicable industrial incremental encoders in the RI58 family are characterised by being particularly flexible. There are a number of different versions offering a range of flanges and connections. These encoders are suitable for high shock loads and feature high signal accuracy and up to 40,000 steps with 10,000 marks and are particularly well suited to use in machine tools, CNC axes, packaging machines, motors / drives, injection moulding machines and sawing machines.
Explosion-proof RX71 incremental encoders with a stainless steel housing have been designed specifically for use in potentially explosive atmospheres. The pressure-resistant housing has been developed in compliance with the EN 60079 series of standards for use in explosive atmospheres and is permitted for use in environments where there is a risk of gas or dust explosion, zones 1 and 21.
