Industrial Applications

1. Robotic Welding Cell Position Verification

In robotic arc or spot welding cells, the sensor detects the presence and correct positioning of metal workpieces or clamping fixtures before the welding cycle initiates.

Problem Solved

Standard sensors frequently fail due to hot welding spatter sticking to the face or high electrical noise causing false triggers. The PTFE-coated housing and noise-immune IC ensure continuous, reliable operation.

2. Stamping Press Die Detection

Mounted near the tooling of an automotive or metal stamping press to verify the full closure of the die or the ejection of the formed metal part.

Problem Solved

The demanding industrial environment generates electromagnetic interference and vibration that can cause standard sensors to fail. The specialized IC resists noise, and the flush M18 design fits securely into tight spaces without protruding.

3. Automated Assembly Line Fixture Indexing

Used to identify metallic pallets or fixtures as they index along heavy-duty assembly lines, signaling PLCs to stop the conveyor accurately at workstations.

Problem Solved

Reliable position confirmation is essential for high-throughput assembly. With a long 7 mm sensing distance and fast 250 Hz response time, it guarantees precise, repeatable stopping without the need for close-contact mechanical switches.
