Why Choose the ABB Orion3-4-M1C-050 Passive Safety Light Grid Unit?
The ABB Orion3-4-M1C-050 (2TLA022306R1000) is the passive mirror unit for a two-beam Orion3 Base safety light grid used for body detection and access protection around hazardous industrial machinery. Although sometimes listed under the alternative designation Orion3-4-M2C-050-B, ABB identifies part number 2TLA022306R1000 as the Orion3-4-M1C-050 passive unit.
Designed for an Orion3 system with a 500 mm protected height, the passive unit works with two optical beams and supports a complete safeguarding system with an operating range of up to 8 m. Orion3 uses an innovative active/passive arrangement in which both the transmitter and receiver are incorporated into the powered active unit, while mirrors in the passive unit return the optical beams.
Because the passive side requires no electrical power or safety wiring, Orion3 can reduce cabling requirements compared with conventional transmitter-and-receiver light grids. Its sturdy profile, IP65 protection and compact construction make the Orion3-4-M1C-050 well suited to machine entrances, automated cells and industrial perimeter access points.

Simplified Active-Passive Access Safeguarding
ABB Orion3 differs from conventional light grids by incorporating both the optical transmitter and receiver into the active unit. The Orion3-4-M1C-050 is installed opposite that active unit and uses integrated mirrors to return the two optical beams. If a person interrupts the beam path, the active safety unit detects the interruption and allows the correctly designed machine safety system to initiate the required safe response.
This active/passive arrangement means that electrical power and safety wiring are required on only one side of the protected access point. The passive Orion3-4-M1C-050 therefore helps reduce cabling across machine entrances while providing a robust optical solution for body detection over distances up to 8 m. Both the appropriate active and passive units are required to form the complete Orion3 Base safeguarding system.
Typical Applications
- Body detection at hazardous machine access points.
- Perimeter safeguarding around automated machinery.
- Robotic manufacturing and assembly cells.
- Machine loading and unloading entrances.
- Material handling and conveyor installations.
- Packaging and processing machinery.
- Production areas where wiring is preferred on only one side.
- Industrial access points requiring two-beam optical protection.
