Why Choose the ABB 2TLA020055R3100 OCB-2A Connection Box?
The ABB 2TLA020055R3100 is an OCB-2A sensor connection box designed to simplify the wiring of multiple voltage-free safety sensors in industrial machine-safety systems. It provides connections for up to four safety sensors, allowing their safety signals to be connected in series while retaining an individual information signal from each sensor.
The OCB-2A provides four M12 5-pole female sensor connections and a single M12 8-pole male connection towards the safety controller in the control cabinet. This arrangement can significantly reduce machine cabling because only one multi-core connection needs to run between the sensor connection box and the cabinet.
Designed for robust industrial installations, the 2TLA020055R3100 operates at 24 V DC, provides an IP67 degree of protection and operates across an ambient temperature range of -25 to +80 °C. Any unused sensor connector must be fitted with an ABB JST2 termination plug to complete the intended installation.
Key Advantages
- Connects up to four voltage-free safety sensors through one compact connection box.
- Safety signals from connected sensors are wired in series.
- Provides an individual information signal from each sensor.
- Reduces cabling between machine-mounted safety devices and the control cabinet.
- Four M12 5-pole female sensor connections simplify field installation.
- Single M12 8-pole male interface connects towards the safety controller.
- IP67 protection supports installation in demanding industrial environments.
- Wide -25 to +80 °C operating temperature range.

- IP67 degree of protection.
- Unused sensor ports require JST2 termination plugs.
- Compact black industrial housing.
Simplified Wiring for Multiple Safety Sensors
Installing several machine-safety devices individually can require numerous cables between the machinery and control cabinet. The ABB OCB-2A provides a decentralised connection point for up to four compatible voltage-free safety sensors, allowing their serial safety circuit and individual information signals to be consolidated into a single cabinet connection.
Each sensor connects through an M12 5-pole female interface, while the OCB-2A connects to the safety controller through an M12 8-pole male interface. This arrangement is particularly useful for machine guarding systems with several safety switches or emergency-stop devices located around the same machine area.
Typical Applications
- Serial connection of voltage-free safety sensors.
- Machine guarding and interlocking systems.
- Emergency-stop circuits with compatible voltage-free devices.
- Industrial production and assembly machinery.
- Automated manufacturing cells.
- Packaging and processing equipment.
- Material-handling and conveyor systems.
- Machine installations requiring reduced control-cabinet cabling.
