Spamel LK112 Limit Switch, 1NO 1NC, Metal/Plastic, Roller Plunger

The Spamel LK112 limit switch is a high-quality industrial component engineered for precise position detection and mechanical control. Featuring a 1NO 1NC contact configuration, this device provides versatile switching capabilities for various electrical circuits. The construction combines a robust metal and plastic housing, offering a balance between durability and lightweight design, while the roller plunger actuator ensures consistent and accurate triggering in demanding environments.

Advantages

This limit switch stands out due to its reliable mechanical performance and sturdy build quality. The integration of both normally open and normally closed contacts allows for flexible integration into complex control systems and safety interlocks. Its design is specifically optimized for longevity, ensuring that it maintains operational integrity even after repeated cycles in industrial settings. The roller plunger mechanism is particularly effective for applications requiring smooth contact with moving parts, reducing wear and tear on both the switch and the machinery.

Suitable for

• Automation systems and assembly lines
• Machinery position monitoring
• Safety interlock circuits
• Conveyor belt control systems
• Industrial equipment limit detection

When it may not be suitable

This switch is not intended for use in environments with extreme corrosive chemicals or high-pressure washdown conditions that exceed its ingress protection rating. It is also not suitable for high-current power switching applications, as it is designed primarily for control circuit signaling.

Key specifications

• Contact configuration: 1NO 1NC
• Actuator type: Roller plunger
• Housing material: Metal and plastic
• Application: Industrial control circuits

How to use

Installation should be performed by qualified personnel in accordance with local electrical standards. The switch should be mounted securely to a stable surface using the provided mounting points, ensuring that the roller plunger is correctly aligned with the moving object it is intended to detect. Once mounted, connect the electrical wires to the appropriate terminals according to the desired control logic. Periodically check the alignment and mechanical movement of the actuator to ensure continued accuracy.

What to consider before purchase

• Verify the physical dimensions to ensure compatibility with your existing mounting space.
• Confirm that the electrical load requirements fall within the rated capacity of the switch.
• Check the environmental conditions of the installation site to ensure the housing material is appropriate.

Usage recommendations

Regularly inspect the roller plunger for signs of mechanical wear and ensure that the switch housing remains free of debris to maintain optimal performance and safety.
