PT65312 is a 4-position rotary DIP switch from the PT65 series featuring a spindle actuator and binary coded decimal (Code 12) encoding. The switch incorporates a 3 + 3 terminal layout with gold over nickel plated bronze contacts and terminals, completely sealed for process compatibility. It operates at a maximum voltage of 24 VDC with a static contact rating of 400 mA and dynamic contact rating of 150 mA, delivering a switching capacity of 1.5 VA maximum. The device features precision-designed detent action with a minimum torque of 7.0 inch-oz (0.7 Ncm), an expected life of 10,000 switching operations, and operates reliably across a temperature range of -20°C to 70°C. PT65312 is ideal for industrial control systems, equipment configuration, and applications requiring compact, sealed rotary switching with extensive coding options.
