Limit switch (metal / plastic) spring lever LK\168

Limit switch of the LK series is a reliable device designed for precise position detection in automatic drive, control, monitoring and measurement systems. The connector design, combining durable plastic with metal elements, ensures both mechanical durability and resistance to harsh environmental conditions.

Construction and application

LK limit switches are characterized by their compact size and the possibility of mounting in places with limited space. The built-in spring mechanism with double action guarantees smooth operation and long life. The design with a hole facilitates cable routing, which simplifies the installation process. The device is particularly useful where precision and reliability are required, e.g. in industrial machines and equipment, transport systems or automatic gates. Thanks to the possibility of choosing different actuating elements (plungers and rollers), the switch can be adapted to the specific needs of the application.

Key features and benefits

• Versatility: Available models with different types of plungers (standard, with a roller parallel or perpendicular to the mounting plane) allow adaptation to different types of movement and forces acting on the actuating element.
• Durability: Solid construction of plastic and metal provides resistance to mechanical damage and external factors. The switch withstands up to 3 million mechanical cycles.
• Safety: Designed for safety circuits (compliance with standards), which increases the level of protection in critical applications.
• High reliability: Snap-action contact ensures precise switching of electrical circuits, minimizing the risk of errors in system operation.
• Protection: IP65 protection class guarantees resistance to dust and water ingress, enabling operation in harsh industrial conditions.
• Adaptation to loads: Rated operating current up to 5A for AC-15 and 0.4A for DC-13 allows use in various electrical circuits.
• Wide temperature range: The ability to operate in a temperature range from -10°C to 70°C means that the switch can be used in various industrial environments.

Technical parameters and additional information

The switch has two contact circuits – one normally open and one normally closed – which allows the implementation of various control functions. The rated insulation voltage is 500V AC, and the rated impulse withstand voltage is 6kV. The device is adapted to work with wires with a cross-section from 1.0 mm² to 2.5 mm² (stranded) or from 1.5 mm² to 4 mm² (solid). It is worth paying attention to the forced disconnection – the lack of this function means that additional protection must be provided in the event of a short circuit. The switch does not have a status indicator or electronic output.
