Limit switch LK-20 W0-59-351022

Limit switch – a reliable automation component

The LK-20 limit switch is a solid device designed for precise control in automation systems. Made with a metal housing, it ensures durability and resistance to mechanical damage. The LK-20 model features a changeover contact design with a plunger, meaning that after activation of the actuator, the contacts first close and then open. This solution works well in applications requiring precise detection of position and motion control.

Construction and application

Limit switches from the LK series are used in a wide range of industrial and building automation applications. They are used in machines and equipment where it is necessary to monitor the position of moving parts, such as gates, doors, conveyors or robots. The metal housing protects the internal components from environmental influences, which increases the reliability of the device. Therefore, the LK-20 switch can be used even in harsh industrial conditions.

Key features and parameters

This model combines a compact design with high technical parameters. The rated insulation voltage is 500V, and the rated operating voltage is 500V AC or 220V DC. The continuous current that the switch can withstand is 16A, and the AC15 and DC13 switching currents are 4A and 0.5A, respectively. It is worth noting the high mechanical durability – as many as 3 million operating cycles. In addition, the device is compliant with the PN-EN 60947-5-1 standard, which confirms its safety and quality of workmanship. The IP56 protection class provides protection against water jets and dust. The speed of the actuator can range from 0.1 to 5 m/s, providing great flexibility in selection for a specific application. The cross-sections of the wires are 1.5…4 mm² for solid wires and 1.0…2.5 mm² for stranded wires.
