Industrial Applications

1. AC Conveyor End-Stop Position Detection

Mounted at conveyor transfer points, the sensor detects ferrous stops, pallets, or machine flags without mechanical contact. Its 100-240 VAC AC 2-wire design allows direct integration into legacy conveyor control circuits that already use AC limit inputs.

Problem Solved

Replaces wear-prone mechanical limit switches in AC-powered material handling equipment while maintaining simple wiring and providing non-contact detection.

2. Metal Guard and Actuator Presence Sensing on Packaging Machines

The unshielded 15 mm sensing range and M30 body suit detection of steel brackets, guard tabs, and actuator plates on larger packaging equipment. IP67 sealing supports washdown splash and dusty production areas.

Problem Solved

Provides reliable metal target confirmation where mechanical switches fail from vibration, contamination, or repeated contact.

3. Retrofit Machine Home/Limit Detection in AC Control Panels

For older machine tools and auxiliary equipment using AC control voltages, this sensor can be installed as a home or travel limit detector without adding a separate DC sensor supply. The 20 Hz response is appropriate for moderate-speed position confirmation.

Problem Solved

Enables straightforward modernization of legacy AC machines by adding non-contact position sensing with minimal control cabinet redesign.
