Schmersal SLB miniature safety light barriers

The SLB series of safety light barriers from Schmersal are claimed to be the smallest safety light barriers. With small dimensions and built-in analysis, the range includes SLB 240 (Type 2), SLB 440 (Type 4) and SLB 450 (Type 4).

Standard features include an integrated safety monitoring module, automatic start or restart interlock, Safe OSSD outputs, integrated visual indication, four-stage optical coding for multiple units in close proximity, prewired or M12 connectors and IP67. Range is up to 15 m with the SLB 240/440 and up to 75 m for the SLB 450.

An optional electric heater is available on the SLB 450 to offer frost-free operation in low-temperature applications down to -30°C, making it suitable for applications that require protection of equipment within cool rooms, freezers and outdoor applications.

The range can be used on all equipment where a narrow protective height is required or the equipment length is long. Example industries include paper and printing, timber processing, mining, packaging and warehousing.
