Product Introduction
Our SF4B-C Safety Light Curtain Type4 PLe SIL3 is a compact safety light curtain series designed for aluminum profile mounting. It adopts a structure that can be embedded into aluminum frames to maximize the use of opening space and reduce blind spots during installation. With IP65 protection rating, it is certified with CE, TÜV, JIS and OSHA/ANSI standards, suitable for machine safety guarding in industrial automation.
Key Benefits
▶Side mounting design: The light curtain will not extend beyond the opening, thin profile minimizes protrusion after installation.
▶Resin base & metal inner frame: Unique dual construction combines lightweight resin base and rigid metal inner frame.
▶Large status indicator: Central orange indicator shows working status and prevents accidental light masking (available for SF4B-□CA-J05).

FAQ
Q: What benefits come from its dual resin and metal inner frame construction?
A: The unique dual-layer design combines lightweight resin base and sturdy metal inner frame. It balances light weight and structural rigidity, delivering stable long-term performance in industrial workshop environments and improving the overall service life of the safety light curtain.
Q: What is the merit of the large central indicator lamp?
A: The large orange indicator installed at the center clearly shows the working status of the light curtain. It can effectively prevent accidental light masking, and supports multiple usage scenarios such as optical axis invalid indication and operation status display for convenient on-site checking.
Q: What advantages does its detection performance offer for automation production?
A: It supports detection distance ranging from 0.3m to 7m. Two optional pitch specifications are available: 20mm pitch for detecting Φ25mm opaque objects and 40mm pitch for Φ45mm opaque objects. Flexible response time adapts to different automation machine safety guarding demands.
