Tapeswitch B-Series Safety Light Curtains are full-featured, microprocessor-controlled units designed for optical guarding applications. These photoelectric barriers are suitable for high-risk automation and machine control applications. Special capabilities include beam blanking and a flexible interface that is compatible with common safety relay units, controllers, and fail-safe PLCs. A wide range of sizes and resolutions is available.

B-Series Safety Light Curtains include an emitter and receiver pair that, by themselves, constitute a complete light curtain system. They provide two redundant solid state PNP type outputs and qualify as a type 4 safety device in accordance with EN61496-1. These outputs can be interfaced directly into the machine control circuit, provided that the circuitry is compatible with PNP type outputs (i.e. safety relays, emergency stop relay packages, Fail-Safe PLC's, etc.).
