Spamel LK200 Limit Switch, 1NO 1NC, Plastic Housing, Roller Plunger

The Spamel LK200 is a high-quality limit switch engineered for reliable performance in industrial automation and control environments. This device features a versatile 1NO (normally open) and 1NC (normally closed) contact configuration, allowing for flexible integration into various electrical control circuits. Housed in a durable, impact-resistant plastic casing, the switch is designed to withstand the rigors of daily operation while maintaining precise switching accuracy. The integrated roller plunger actuator ensures smooth interaction with moving machine components, making it an essential component for monitoring position, travel limits, or the presence of objects in automated systems.

Advantages

The primary advantage of the Spamel LK200 lies in its robust construction and reliable contact mechanism, which ensures consistent performance even in demanding industrial settings. The use of a high-grade plastic housing provides excellent electrical insulation and protection against environmental factors, while the roller plunger design minimizes mechanical wear during contact with moving parts. Its compact design allows for easy installation in space-constrained areas, and the dual-contact configuration offers significant flexibility for complex control logic requirements.

Suitable for

• Monitoring the travel limits of automated doors and gates
• Detecting the position of machine components on assembly lines
• Integration into safety interlock systems for industrial machinery
• General-purpose presence detection in electrical control circuits

When it may not be suitable

This limit switch is not intended for use in environments with extreme temperatures, high levels of corrosive chemicals, or heavy exposure to direct moisture, as the plastic housing may degrade under such conditions. It is also not suitable for high-current power switching applications, as it is designed specifically for control circuit signaling.

Key specifications

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

How to use

Installation should be performed by a qualified technician in accordance with local electrical safety 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 control wires to the appropriate terminals according to the desired normally open or normally closed logic. After installation, perform a manual test to verify that the actuator triggers the switch correctly at the intended position before putting the system into full operation.

What to consider before purchase

• Verify that the mechanical travel distance of your machine matches the operating range of the roller plunger
• Ensure the electrical load of your control circuit does not exceed the rated capacity of the switch
• Check the mounting dimensions to ensure compatibility with your existing equipment

Usage recommendations

Regularly inspect the roller plunger for signs of mechanical wear and ensure that the mounting hardware remains tight to maintain precise detection accuracy over the long term.
