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 GRTB 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 P2406 typically denotes a protective field height of 240mm. This height is designed to protect a specific danger zone effectively.

Long Operating Range (S07): The S07 suffix signifies a standard range of 0.5 to 7 meters between the transmitter and receiver. This allows for flexible installation around larger machines.

Muting Function (Capability): This variant is equipped for muting. This advanced function allows the temporary, safe suspension of the safety field (e.g., using additional sensors) to permit materials to pass through the light curtain without triggering a stop, while still protecting personnel. This is essential for automated production lines.

Blanking Function (Capability): Supports fixed and floating blanking, which allows one or more beams to be selectively ignored to accommodate for permanent obstructions (like machine pillars) within the protective field without compromising the overall safety integrity.

Robust Metal Housing: Housed in a robust anodized aluminum profile with a high IP65 protection rating, 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.
