Product Features

Meeting the highest safety standards

Achieves safety levels up to PLe and SIL3, categorized as Type 4, aligning with international standards, and simultaneously equipped with UL certification and authoritative TÜV certification.

Blind-zone-free safety design

Edge-to-edge installation method, meeting the requirements for compact and narrow installation spaces.

Optical sync supported for diverse wiring setups

Free selection between line synchronization and optical synchronization, supporting flexible A/B light switching to prevent mutual interference.

Reliable safety design

Type 4 light curtain features a dual-CPU and dual-output self-test design to prevent safety hazards caused by the failure of a single circuit.

Compact size with high protection

With a cross-sectional area of only 29mm*38mm, it achieves a maximum protection rating of IP67.

Ultra-long detection distance with excellent angle control

Supports a detection distance of 0.2 to 10m, with high compatibility within a single model, and a maximum beam divergence angle of ±2.5°.
