The 83845001 is a universal limit switch featuring a steel roller plunger actuator designed for reliable position detection in industrial automation systems. It incorporates a four-terminal double break two-way contact element (form Za) with snap-action operation, housed in a metal case with three cable entries and heads adjustable in 90° increments. The switch is protected by a nitrile boot and offers IP66 degree of protection per IEC 60529, with conformity to IEC/EN 60947-5-1 standards. Key mechanical characteristics include a maximum operating force of 10 N, maximum total travel force of 22 N, and mechanical life rating of 107 operations over an operating temperature range of -10°C to +70°C. The device features an assigned insulation voltage of 500 V, assigned impulse voltage of 4000 V, and thermal current rating of 10 A, making it suitable for AC15 240 V 3 A and DC13 125 V 0.55 A applications. This limit switch is commonly used in machinery control, conveyor systems, and automated production lines where precise position sensing and reliable switching are essential.
