Why Choose the ABB Orion3-4-M2C-120 Passive Safety Light Grid Unit?
The ABB Orion3-4-M2C-120, ordering code 2TLA022306R1400, is a robust passive safety light grid unit designed for body detection and access protection around hazardous industrial machinery. As part of the ABB Orion3 Base safety light grid series, it works with a compatible Orion3 active unit to provide reliable electro-sensitive machine guarding with reduced cabling requirements.
Unlike conventional safety light grids that require separate powered transmitter and receiver units, the Orion3 Base design incorporates the transmitter and receiver functions into the active unit while the beams are reflected by the passive unit. This means electrical power is required on only one side of the protected area, simplifying installation around machinery, doors, access points and production equipment.
The Orion3-4-M2C-120 is the four-beam passive unit for a 1200 mm protected height. When paired with the corresponding Orion3-4-K2C-120-B active unit, the system provides an operating distance of up to 8 m and supports high-level machine safety applications including Type 4, PL e, Category 4 and SIL 3 installations.
Key Advantages
- Passive unit for the ABB Orion3 Base safety light grid system.
- Four-beam configuration with 1200 mm protected height for body detection and access protection.

Reliable Access Protection for Industrial Machinery
Safety light grids are used to detect people entering hazardous areas around automated machinery and production equipment. The ABB Orion3 Base system is specifically designed for body detection applications, helping machine builders create reliable access protection without requiring electrical cabling on both sides of the guarded opening.
The Orion3-4-M2C-120 forms the passive side of the system and reflects the infrared safety beams back towards the corresponding active unit. This architecture helps reduce installation complexity while retaining the high functional safety performance required for demanding industrial machine guarding applications.
Typical Applications
- Industrial machine access protection.
- Robotic cells and automated production areas.
- Conveyor and material handling systems.
- Packaging and processing machinery.
- Palletising and manufacturing cells.
- Guarded entrances where electrical power is available on only one side.
