Dome pusher LSM-11S 266140

Limit switch with dome plunger – reliable protection and precise operation

This limit switch, designated LSM-11S, is a solid and durable device designed for industrial and other applications. The construction based on a metal housing provides high resistance to mechanical damage and external factors. This switch is used in safety systems where reliable operation is crucial.

Construction and application

The LSM-11S switch is characterized by snap-action contacts, which means it switches the circuit both when pressing and releasing the plunger. This type of operation is particularly useful in applications requiring precise detection of the position of a moving element. The housing with IP66/IP67 protection rating guarantees dust and water tightness, enabling operation in harsh environmental conditions. Equipped with a metric cable gland, it facilitates connection to the electrical installation.

It will find application in:

• Industrial machines and equipment
• Automation systems
• Safety-related applications (e.g., emergency stop switches)
• Mobile devices exposed to harsh weather conditions

User parameters and benefits

The LSM-11S switch has been designed with reliability and safety in mind. Forced contact separation ensures a certain circuit interruption in the event of a failure or overload. A wide operating temperature range (-25°C to 70°C) allows operation in various climatic conditions. Thanks to its compact dimensions (31 mm width, 61 mm height and 33.5 mm length), the switch easily integrates with existing structures.

• Durable metal housing: Provides protection against mechanical damage and corrosion.
• High degree of protection IP66/IP67: Guarantees dust and water tightness, enabling operation in harsh conditions.
• Snap-action contacts: Ensure circuit switching both when pressing and releasing the plunger – ideal for precise position detection.
• Forced contact separation: Increases safety by ensuring a certain circuit interruption in the event of a failure.
• Wide operating temperature range: Enables operation in various climatic conditions (-25°C to 70°C).
• Intended for safety circuits: Confirmed by the device's certification and construction.

The switch allows for safe switching of circuits with a rated operating current of up to 6A for AC-15 (at voltages of 24V, 125V and 230V) and up to 3A for DC-13 (at 24V voltage), 0.8A (at 125V voltage) and 0.3A (at 230V voltage). The dome plunger with parallel roller ensures smooth and precise operation of the switch.
