Industrial Limit Switch with Adjustable Lever and Roller
The ME-8108 limit switch provides automatic control for industrial equipment and automatic gates through reliable mechanical detection. With a 2NC + 2NO configuration and a capacity of 5A at 250V AC, it is the professional solution for workshops, machine tools, and automation systems that require precise switching when reaching the limit position.
What you get with this product
- Universal mounting on CNC machines, milling machines, lathes, and automatic gates via a standard 4mm threaded fixing system
- Easy adjustment of the activation point with an 11cm adjustable lever and a movable pivoting roller
- Dual function in a single device — 2 normally closed and 2 normally open contacts for complex control
- Robust construction from metal alloy and industrial plastic resistant to repeated mechanical wear
- Quick installation without major modifications — integrates into existing electrical circuits via standard connections
- Operational safety in industrial environments through 250V AC insulation and 5A switching capacity
How it works and how to install it
The switch is fixed to a rigid surface through the threaded mounting hole, then the lever's position is adjusted so that the roller is touched by the movable element (door, machine table, plate) at the desired position. Upon mechanical contact, the roller actuates the internal lever, which simultaneously switches the NC contacts (closes the circuit) and NO contacts (opens the circuit), generating the electrical signal for stopping or changing direction.
Electrical connections are made via the screw terminals on the bottom of the housing, according to the diagram inscribed on the product label. The lever can be oriented at several angles, and the 11cm length allows for fine adjustment of the trigger point.
Frequently asked questions
Can I use this switch for an automatic garage door?
Yes, it is perfectly suitable for detecting the limit position on garage doors or swing gates, ensuring the motor stops at full opening or closing.
What does the 2NC + 2NO configuration mean and how do I use it?
It means you have 2 contacts that are closed at rest and open upon activation (NC), plus 2 contacts that are open and close upon activation (NO). This allows you to control two different circuits simultaneously or provide redundancy.
Will it withstand wear if activated hundreds of times daily?
Yes, it is designed for industrial use with repetitive cycles. The roller and metal bearing reduce friction, and the contacts are dimensioned for a long lifespan under frequent switching conditions.
