They each feature the Swiss Click Indexing System, which ensures consistent torque over the life of the encoder, and provide an excellent indexing feel with 0.5Ncm, 1.5Ncm, 2.0Ncm or 2.5Ncm switching torque. The encoders have an operational life of up to a million revolutions. Available for vertical or horizontal mounting with threaded or non-threaded bushing, the E37 encoders have a 11.5 x 12.3 x 9.1mm metal housing with metal, shaft, gold-plated contacts, have an operating temperature range of -40C to +85C, are MIL-STD-202G compliant and have optional IP60 or IP68 front-panel sealing.
Various customisation options are available, including shaft dimensions and shape, switching torque and pushbutton actuation force, indexing resolution and PPR. A full range of matching control knobs of various heights and diameters is available for the E37 encoders. Typical applications include cockpit controls, radios and navigation, desktop and mobile radios, professional portable audio equipment and applications where the user interface is space critical.
