| Description |
The GS-Series Light Curtains are a full featured, cost effective microprocessor controlled light curtain set. The GS-Series Light Curtains are available in two versions. The GS120 series, for low risk applications, per EN61496-1 (type 2). The GS140 series for high risk applications per EN61496-1 (type 4). Both series have a flexible interface that is compatible with common safety relays units, controllers and fail safe PLC’s. A wide range of sizes and resolutions are available.
The GS series emitter and receiver pair, by themselves, constitutes a complete light curtain system, which provides two redundant solid state PNP outputs in accordance with EN61496-1. These outputs can be interfaced directly the machine control circuit, provided that the circuit 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. |
