Industrial Applications
Manufacturing Automation
Position detection in assembly lines, part presence verification, and machine guarding applications. The 1 kHz switching frequency enables high-speed production monitoring.
Material Handling
Object detection on conveyor systems, pallet positioning, and robotic arm end-effector sensing. IP67 rating ensures reliability in dusty warehouse environments.
Packaging Machinery
Product counting, fill level detection, and packaging material presence verification. The 3mm sensing distance provides precise detection without physical contact.
Automotive Industry
Component positioning in assembly processes, robotic welding cell safety, and quality control inspection stations. Chrome-plated housing resists automotive fluids and chemicals.
Installation Best Practices
Mounting Considerations: Ensure proper clearance around the sensor (typically 2x diameter) to prevent interference from adjacent metal objects. Use the included mounting hardware for secure installation.
Wiring Guidelines: Connect brown wire (+VDC), blue wire (0V/GND), and black wire (signal output) according to standard PNP wiring conventions. Always verify voltage polarity before powering.
