Key Features & Strengths:

Highest Safety Integrity (Type 4 / Category 4): This is a key feature. It meets the most stringent safety standards (IEC 61496-1 Type 4, ISO 13849-1 Category 4, PLe, SIL 3), making it suitable for safeguarding high-risk machinery where serious injury is possible.

Compact Profile & Through-Beam Design: The "T" in GRTE indicates a Through-Beam design, consisting of a separate Transmitter (Emitter) and Receiver unit. This provides the most reliable and stable detection over longer ranges, immune to environmental factors like dust or surface reflectivity.

High Resolution for Finger Protection: The model number indicates a 18mm resolution (the spacing between the individual beams). This fine resolution is designed specifically for finger and hand protection, preventing access to hazardous areas.

Protective Field Height: The suffix N1112 typically denotes a protective field height of 1112mm. This larger height is designed to protect access to entire hazardous zones, such as the front of a large press or robot cell.

Long Operating Range: The GRTE series typically offers a long operating range (e.g., up to 9 meters or more between transmitter and receiver), allowing for flexible installation around larger machines.

Advanced Safety Functions: Supports advanced safety functions like BlankING (allowing the masking of one or more beams to accommodate for fixed obstructions within the protective field without compromising safety) and Muting (temporary, safe suspension of the safety field for automated material flow).

Robust Metal Housing: Housed in a robust anodized aluminum profile with a high IP65 protection rating (or higher), ensuring durability and reliable operation in harsh industrial environments resistant to dust, moisture, and oils.

Clear Status Indication: Features multi-segment LED indicators on both units for clear visual feedback on alignment, power, status, and diagnostics.
