Limit switch (plastic) with roller plunger LK\291

Limit switch – a reliable safety and control element

This limit switch with a plastic housing and a roller plunger is a robust solution for precise position detection in various industrial applications. It will work well in both simple systems and safety systems where reliable operation is crucial. The roller design ensures smooth activation even with slight movements, minimizing the risk of mechanical damage.

The switch is designed for durability and resistance to harsh working conditions. The plastic housing protects the internal components from moisture and dust (IP65 protection class), and the wide operating temperature range (-10 to 70°C) allows it to be used in various environments. A metric cable gland facilitates connection of wires, and compact dimensions (30 x 30.6 x 53 mm) allow for mounting in confined spaces.

Construction features and application

This switch is characterized by two switchable contacts (one normally open, one normally closed) with a momentary contact, which means that a brief interruption of contact occurs during switching. The rated operating current of up to 5A for AC-15 and DC-13 ensures compatibility with various loads. The parallel roller plunger enables precise position detection, and the large deflection angle (+/-95°) increases installation flexibility and adaptation to specific needs. The switch is designed for safety circuits, confirming its usefulness in applications requiring a high level of reliability and protection.

Additionally, it is worth mentioning the high mechanical resistance (over 10 million cycles) and electrical resistance (over 500 thousand cycles), which guarantees a long service life even with intensive use. The roller and spring made of stainless steel ensure corrosion resistance and long-term maintenance of mechanical properties.
