Description: These RoHS-compliant rotary encoders feature a compact 8mm design with options of a SPST momentary switch and dual encoders with concentric shafts. This 3-model series is suitable for a wide range of applications including digital audio/video equipment, navigation systems, appliances and machine tools. The encoders have a mechanical -type contact and are sealed to IP50 specifications. The EN08 series feature a 2-bit Gray code. Their versatility and options make them one of the most easily integrated encoder series on the market. The compact 8 mm encoders have 20 detents per revolution with rotational torque of detent rated at a maximum of 1.0 oz-in. The operating life is 50,000 cycles, and the optional SPST momentary switch life is rated at 15,000 actuations. The encoders feature a maximum operating speed of 30 RPMs at 10 pulses per revolution. The closed circuit resistance is rated at a maximum of 3.0 Ohms with a 1.0 mA/5Vdc contact rating. The SPST switch has a maximum operating force of 850 gf and travels up to 0.5 mm. Operating temperatures range from –30°C to +70°C. Applications: Audio/video control Navigation systems Test instrumentation Speed control Menu selection Features: 8 mm rotary encoder 2 bits Gray code Incremental / contacting type Metal bushing / shaft S.P.S.T. momentary switch option Dual encoders with concentric shaft RoHS compliant Model Styles Available EN08-N Side adjust, single encoder EN08-S Side adjust, single encoder, with momentary switch EN08-C Side adjust, dual encoders, concentric shaft
