B-Series Safety Light Curtains
 

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.).

Explanation of Terminology
EN 61496 Type 4 Design
This is an international safety standard with particular requirements for equipment using active opto-electronic protective devices. It is the highest level of the most stringent standard in the world, acceptable and suitable for the most dangerous machines.
CE Certification
The CE mark is a European marking that indicates conformity with specific safety requirements of the European Union. CE certification means that a product has met these requirements.

Beam Blanking
Beam blanking allows selected areas of the sensing field to be disabled. This is useful in applications where fixed objects such as workpiece supports protrude through the light curtain and interrupt one or more beams.
Fixed Blanking
Specific beams are programmed to be obstructed and, consequently, disabled.
Floating blanking
An obstruction can move or ‘float’ within the detection zone without generating a stop signal.
