A new rotary encoder has been introduced by knitter-switch. The company’s MER 23-20 encoders feature a large hollow shaft which allows system designers to incorporate an LED or tactile switch within the device. This makes them ideal for applications such as home multimedia systems, car entertainment systems and measuring instruments.

Each turn of the encoder is 20 pulses and one cycle is a full 360º CW followed by a 360º CCW turn. The encoder has a 9x9mm square hole at the centre which allows the placement of an LED and/or tactile switch on to the encoder’s internal PCB. With a minimum lifetime of 30,000 cycles the devices offer users a reliable and robust control solution. Operating temperature range of the new encoder is is -10ºC to 70ºC.
