Limit switch LK-20R W0-59-351042

Limit switch – reliable circuit protection

The LK-20R limit switch is an element used to precisely switch off circuits when a moving element of a machine or device reaches its extreme position. This model, characterized by a changeover function, finds application in various industrial applications and automation. The metal housing provides durability and resistance to mechanical damage, which is crucial in demanding working conditions.

Construction and application

This limit switch with a plunger and roller has been designed to operate in systems requiring frequent switching. Its construction allows for effective operation even at high speeds of the drive element (0.1…5 m/s). The use of a gG16A fuse insert provides additional protection against the effects of short circuits and overloads. Thanks to compliance with the PN-EN 60947-5-1 standard, its reliability and safety of use can be ensured.

Key features and benefits

• Mechanical durability: Designed for intensive use, it withstands up to 3 x 10⁶ operating cycles.
• Resistance to external conditions: A wide range of ambient temperatures (-25…+40°C) and a high degree of protection IP56 (terminals) allow operation in difficult industrial conditions.
• Safety: The rated insulation voltage U_i is 500V, and the rated switching voltage U_e is 500V AC / 220V DC, which ensures safe operation of the installation.
• Versatility: The possibility of connecting wires with a cross-section from 1.0 to 2.5 mm² facilitates integration with various electrical installations.
• Precision of operation: The force required to move the plunger is a maximum of 23N, which guarantees certain and repeatable operation.
• Compliance with standards: Meets the requirements of the PN-EN 60947-5-1 standard, which confirms its quality and safety of use.

The LK-20R switch is a solid solution for installers looking for a reliable safety element and for end-users who value the safety and long-term operation of devices.
