Rotary encoder

11 May 2011 Switches, Relays & Keypads

New from knitter-switch is the MER 23-20 rotary encoder which features a large hollow shaft, allowing system designers to incorporate an LED or tactile switch within the device.

This makes them suitable for applications such as home multimedia systems, car entertainment systems and measuring instruments.

Each turn of the encoder produces 20 pulses and one cycle is a full 360° clockwise followed by a 360° counter-clockwise turn. The encoder has a 9 x 9 mm square hole at its centre which allows the placement of an LED and/or tactile switch on to the encoder’s internal PCB. The MER 23-20 offers a minimum lifetime of 30 000 cycles and an operating temperature range of -10°C to +70°C.
