Industrial Applications

1. Heavy-Duty Conveyor Jam Detection

Deploys alongside industrial conveyor systems to continuously monitor the movement of metallic pallets and components. The extended sensing distance ensures the sensor remains safely out of the direct path of moving objects.

Problem Solved

Prevents mechanical damage and system downtime by detecting metal objects from a safe 40mm standoff distance, avoiding accidental physical collisions while maintaining high detection reliability.

2. Automated Washdown Facility Position Sensing

Monitors the state and position of automated heavy gates and large valves within food processing or heavy equipment washdown stations where high-pressure hot water cleaning is routine.

Problem Solved

Eliminates premature sensor failure caused by aggressive water ingress, ensuring reliable target tracking without the need for constant maintenance or protective housings.

3. Agricultural Machinery Component Verification

Integrates into mobile and outdoor agricultural equipment to verify the proper deployment and positioning of stabilizing outriggers and mechanical booms in completely exposed environments.

Problem Solved

Provides consistent, non-contact structural metal detection despite severe temperature variations, shock, vibrations, and constant exposure to rain, mud, and dust.
