Overview

A high-quality safety light curtain consists of a transmitter and a receiver, capable of detecting opaque objects exceeding the detection precision entering the light curtain area. SUCH safety light curtain sensors offer selectable optical axis spacing of 10/14/20/25/30/40mm and a choice of 6-32 beams. The detection light source is an infrared LED, with a response time of less than 15ms. Safety light curtains feature short response time, strong anti-interference capabilities, excellent shock resistance, long protection length, high versatility, and convenient installation and debugging. Light curtains are suitable for potentially hazardous equipment and areas such as stamping, shearing, and injection molding processes.

Feature

Aluminum Alloy Housing: The safety light curtain features a recessed back design, allowing for flexible installation depending on the environment. The aluminum alloy housing is robust and durable.
Anti-interference Chip: Utilizing carefully selected SMT chips, it offers high sensitivity, anti-interference capabilities, false alarm prevention, and stable operation.
Shielded Data Cable: The safety light curtain sensor's data cable is waterproof, oil-proof, and shielded, maintaining operational stability even in harsh environments.

FAQ

Q1: What are some common issues with safety light curtains? ❯

Common issues with safety light curtains include dirty or obstructed lenses, misaligned beams, damaged cables, electromagnetic interference, vibration-causing movement, and self-diagnostic failures.

Q2: How does a light curtain compare to other safety devices? ❯

Unlike physical protective shields (which can obstruct passage) or emergency stop buttons (which require manual operation), light curtains offer contactless protection, rapid response, and flexible coverage. They are more convenient, detect faults in real time, and do not restrict the workspace.

Q3: How to inspect a safety light curtain? ❯

Inspect and clean the lens, confirm transmitter and receiver alignment, check wiring and mounting brackets, and perform a functional test by interrupting the beam to confirm the machine stops correctly.
