Customised rotary encoders

17 September 2008 Switches, Relays & Keypads

Knitter-Switch produces a wide range of rotary encoders designed specifically for applications in the consumer, industrial and automotive industries.

Described by some as rotary pulse switches, encoders are compact electromechanical devices which convert rotary motion into a digital pulse or signal.

The company’s latest MER series are offered in vertical or horizontal versions with shaft lengths of up to 25 mm. A variety of shaft types can be specified depending on the end application; these include metal flattened pin, knurled, cut and insulated plastic pin. Custom shafts for most applications can also be provided on request.

With an impulse frequency of between 12 and 24 pulses for each rotation, users can define the encoder’s output to suit their individual requirements. Also, to save PCB space, customers can specify an encoder with an integrated switch, eliminating the need for an extra device.

The encoders feature a contact rating of 5 V d.c., 10 mA and a mechanical life of up to 30 000 operations. Versions are available for PCB mount or single-hole mounting.
