Head with pusher and roller for end stop connector LK 200 LK\291-H

Limit switches – reliability and safety in every circuit

This limit switch, manufactured by Spamel, is a robust solution for precise position detection in various industrial and automation applications. Its design, based on a roller plunger, ensures smooth and reliable operation even in harsh conditions. This switch is particularly useful where overload and short-circuit protection are required, as well as precise process control.

Construction and application

The plunger and roller head for the LK 200 limit switch is an element designed for mounting on standard limit switches. Its task is to convert mechanical movement into an electrical signal that can be used to control various devices. The housing made of plastic provides resistance to mechanical damage and atmospheric factors (IP65 protection). The roller plunger enables smooth operation even with small movements, which is important in applications requiring precision. This switch finds application in:

• Industrial machines and equipment
• Transport and conveyor systems
• Building automation (e.g., gates, blinds)
• Agricultural equipment
• Safety applications – thanks to the possibility of use in safety circuits (For safety circuits: yes)

Key features and benefits

• Versatility: Can be used in a wide range of industrial and automation applications.
• Durability: The plastic housing provides resistance to mechanical damage and atmospheric factors. IP65 protection guarantees tightness against dust and water.
• Precision: The roller plunger ensures smooth operation and accurate position detection.
• Safety: The possibility of use in safety circuits increases the level of protection for machines and equipment.
• Electrical parameters: Rated operating current up to 5A for AC-15 and 5A for DC-13 allows controlling various loads. Snap-action contact ensures reliable switching.
• Wide operating temperature range: From -10°C to 70°C enables operation in various environmental conditions.
• Easy installation: Metric cable gland facilitates connection of electrical wires.
• Contact configuration: It has both normally open (NO) and normally closed (NC) contacts, providing flexibility in control circuit design.

Additionally, it is worth mentioning its compact dimensions (30.6 x 53 x 30 mm), which facilitate integration with existing systems. The design with a parallel roller plunger ensures stable operation and minimizes the risk of false signals.
