Key Features & Specifications:

Feature Specification
Product Type Type 4 Safety Light Curtain (Per IEC 61496-1/2)
Protective Height 180 mm (This is derived from the model number: GRTE18...)
Resolution (Beam Spacing) 14 mm (This is a key part of the typ number: ...-N1147. The "11" often indicates 14mm resolution in SICK coding). This resolution is suitable for finger and hand detection.
Number of Beams 16 beams (For a 180mm height with ~14mm spacing)
Safety Standards IEC 61496-1/2 (Type 4), EN ISO 13849-1 (Performance Level e, Category 4), ISO 13855. Complies with OSHA machinery guarding requirements.
Safety Integrity SIL 3 according to IEC 61508
Operating Range 0.5 m...7 m (The distance over which the transmitter and receiver can be effectively aligned).
Response Time ≤ 15 ms (Very fast response to ensure the machine stops before a hazard is reached).
Outputs 2 OSSD (Output Signal Switching Device) outputs. These are solid-state safety outputs (typically PNP) that switch off when the beam is broken. Note: The "-47" in the part number often specifies the output type and voltage. This model is typically a 24V DC device with PNP OSSDs.
Control & Muting Features an integrated Muting Lamp for visual status indication. It supports external muting and blanking functions (via separate interface modules) for allowing material to pass through the field without triggering a stop.
Housing Robust, industrial-grade aluminum profile with polycarbonate windows.
Connection M12 Connectors (Circular connectors), facilitating quick installation and replacement.
Application Point-of-Operation Guarding: Ideal for protecting press brakes, stamping presses, robotic cells, and other machinery where access to the hazard is required for feeding parts.
