The Story Behind the Components

Position sensing and overtravel protection for machinery that moves.

A limit switch detects when a moving machine part reaches a set position and signals the next action: stop the motor, reverse the direction, or confirm a guard is in place. It is one of the simplest and most reliable sensing devices on a production floor.

PRODUCT SERIES

Each series answers a different set of operating conditions.

TZ-8 Miniature Vertical
Roughly one third the size of a standard vertical limit switch. The terminal section opens fully for fast, hassle-free wiring on tight production lines.
image-71
TSA Sealed Metal
Metal housing with stainless steel roller. Built for environments where the housing itself takes direct impact.
image-72
TLS Plastic Compact
Economical engineering plastic housing that shares the same internal mechanism as the TZ-8 series. Lightweight, cost-effective, and reliable.
image-73
WL Double-Circuit
Die-cast aluminum housing with double-circuit design. Built for heavy-duty environments requiring oil resistance, water resistance, and pressure resistance.
image-74
HL Overtravel
Large overtravel margin ensures smooth, forgiving operation. Ideal for printing machines, forming machines, and other light industrial equipment.
image-75
TZ-6 Aluminium Alloy Sealed
Aluminum alloy sealed housing. DC models feature magnetic blowout for arc suppression.
image-76
TZ-3 Triple-Sealed
Triple-sealed to IP67 rating. Built for outdoor and high-humidity environments where moisture and dust are a concern.

BUILT FOR THE LONG RUN

Precision engineering, from raw material to finished switch.

The housing and the operating head change across series. What stays constant is the attention to material, assembly, and testing.

The right switch starts with the right operating conditions.

We build every switch to the same standard. Matching it to your operating conditions is what makes it last.

WHERE LIMIT SWITCHES WORK

Industries where the right switch keeps equipment running.

Elevator Systems

Car position detection and landing accuracy depend on switches that hold calibration across millions of cycles.

CNC & Machine Tools

Coolant spray, metal chips, and vibration. Switches in machine tools read position through all of it.

Crane & Hoist

Boom limit and hook overtravel protection where a missed signal means more than downtime.

Injection Molding

Mold open and close confirmation, ejector position detection, and safety gate interlocking on high-cycle molding machines.
