Industrial Applications

1. Semiconductor Assembly Line Guarding

High-speed pick-and-place systems and wire bonding machinery are extremely compact. The 13.2mm ultra-slim thickness and dead-zoneless design of the safety light curtain allows it to be mounted directly adjacent to access windows without taking up precious robotic cell footprint.

Problem Solved

Eliminates mechanical safety gates that slow down production, while protecting technicians' fingers (ø14 mm minimum sensing capability) from mechanical pinch points during quick component adjustments.

2. Automated Packaging Conveyor Muting

Conveyor systems feeding components into a robotic shrink wrapper or cartooning area. The integrated muting function of the light curtain disables the safety output when products pass through but immediately trips if a human hand reaches in.

Problem Solved

Avoids false machine stoppages caused by products entering the hazard zone while ensuring continuous and strict 14mm-pitch safety guarding for operators.

3. High-Humidity Food & Beverage Secondary Packaging

Small-scale bottling or secondary packaging machinery operating in humid environments. The IP67 ingress protection rating of the polycarbonate alloy enclosure allows the device to withstand ambient moisture, occasional splashing, and mild washdowns.

Problem Solved

Standard safety sensors fail under moisture ingress and condensation, causing expensive downtime; the IP67-certified safety light curtain provides uninterrupted Type 4 safety performance.
