Industrial Applications

1. High-Speed Label and Splice Detection

Utilizing its ultra-fine 0.05 mm MDO and fast 10 kHz switching frequency, the sensor detects virtually invisible splices or transparent label gaps on continuous fast-moving packaging and converting webs.

Problem Solved

Prevents label dispensing failures and web tension breakage by ensuring ultra-fast, high-resolution edge detection without being affected by high-speed line movements.

2. Miniature Component Verification in PCB Assembly

The precise laser beam checks for the presence and correct orientation of tiny electronic components, lead wires, or pins before placement or soldering processes in automated assembly machines.

Problem Solved

Eliminates assembly defects by reliably detecting micrometer-scale missing parts that standard photoelectric sensors would overlook due to beam divergence.

3. Rotary Indexing and Position Monitoring

Deployed alongside timing discs or slotted gears, the fork sensor acts as a precision optical limit switch to provide exact rotational position feedback or index pulses for servo-driven index tables.

Problem Solved

Reduces mechanical wear from physical limit switches while providing sub-millisecond precision due to a highly stable response time (± 20 µs) and minimal 40 µs jitter.
