Why Choose the ABB Orion3-4-K2C-120-E Safety Light Grid?
The ABB Orion3-4-K2C-120-E is the active unit of an Orion3 Extended Type 4 safety light grid designed for body detection and access protection around hazardous industrial machinery, particularly in applications requiring muting. Orion3 uses an active/passive optical architecture in which both transmitting and receiving functions are incorporated into the powered active unit, while a separately ordered passive unit contains mirrors that reflect the beams.
This model provides 4 optical beams, a substantial 1200 mm protected height and a 400 mm inter-axis distance. Its 419.75 mm device resolution is intended for body detection rather than fine hand or finger detection, while the 0.5–8 m operating range makes it suitable for machine entrances, robot cells, conveyors and automated material-transfer points.
As part of the Orion3 Extended family, the Orion3-4-K2C-120-E is specifically designed for access protection in muting applications. Its single-side powered architecture can simplify installation and reduce machine cabling, while a fast 12 ms response time, PNP safety outputs and high-level functional safety performance provide dependable integration into industrial machine safety systems.

Reliable Access Protection for Muting Applications
The ABB Orion3 Extended architecture incorporates both the transmitting and receiving optical functions into the powered active unit. The corresponding passive unit contains mirrors that reflect the four optical beams back across the protected opening. This means electrical power and safety-system wiring are required on only one side, helping simplify installation around conveyors, automated machinery and material-transfer areas.
When a person interrupts the 4-beam protective field, the safety outputs can signal the associated machine safety system so hazardous movement is stopped or prevented from starting. The Extended version is specifically designed for access protection in muting applications, allowing correctly designed systems to permit authorised material movement through the protected opening while maintaining personnel protection. The active and passive Orion3 components are ordered separately, and both are required for the complete protective system.
Typical Applications
- Industrial machine access protection.
- Conveyor systems requiring muting functionality.
- Automated material-transfer points.
- Robot cell entrances and automated work areas.
- Packaging and palletising machinery.
- Automated production and assembly systems.
- Applications where power and safety wiring are preferred on only one side of the protected opening.
