Why Choose the ABB Orion3-4-K2C-120-B Safety Light Grid?
The ABB Orion3-4-K2C-120-B is the active unit of an Orion3 Base Type 4 safety light grid designed for body detection and access protection around hazardous industrial machinery. Unlike conventional through-beam light grids, Orion3 Base incorporates both transmitting and receiving functions within the powered active unit and works with a separate passive mirror unit that reflects the optical beams.
This model provides 4 optical beams, a substantial 1200 mm protected height and an operating range of 0.5–8 m. Its approximately 419.8 mm device resolution is intended specifically for body detection, making the Orion3-4-K2C-120-B suitable for machine entrances, robot cells and other hazardous access points where personnel entry must be reliably detected.
The Orion3 Base architecture simplifies installation because electrical power and safety-system wiring are required only at the active side of the protected opening. With a fast 12 ms response time, PNP safety outputs, IP65 protection and functional safety performance up to PL e and SIL 3, the Orion3-4-K2C-120-B provides a robust solution for demanding industrial access-protection applications.

Reliable Access Protection with Simplified Wiring
The ABB Orion3 Base design combines both the transmitter and receiver within the powered active unit. A corresponding passive unit containing mirrors reflects the four optical beams back across the protected opening. Because the passive side requires no electrical connection, machine builders can reduce cabling and simplify installation compared with conventional systems that require powered devices on both sides.
When a person passes through the 4-beam protective field, interruption of the beams causes the safety outputs to change state so the connected machine safety system can stop or prevent hazardous movement. With its 1200 mm protected height, 8 m maximum operating range and 12 ms response time, the Orion3-4-K2C-120-B is particularly suited to reliable body detection at industrial machine access points.
Typical Applications
- Industrial machine access protection.
- Robot cell entrances and automated work areas.
- Hazardous-area perimeter access points.
- Automated production and assembly machinery.
- Conveyor and material handling systems.
- Packaging and processing machinery.
- Applications where wiring is preferred on only one side of the protected opening.
