2TLA020051R5701 ABB Adam C OSSD-Info M12-8 Sensor

Why Choose the ABB 2TLA020051R5701 Adam C OSSD-Info M12-8 Sensor?

The ABB 2TLA020051R5701, designated Adam C OSSD-Info M12-8, is a coded non-contact safety sensor unit from the ABB Eden family. Classified within the Sensors/Switches product group, it provides dual OSSD safety outputs together with an information output for monitoring movable guards, doors, hatches and machine positions when paired with a compatible Eva actuator.

This M12-8 version is designed for single and series applications and uses an 8-pole male M12 connector. The information function is available through pins 5 and 8, while the OSSD architecture enables connection to compatible safety relays and safety controllers. The sensor operates from a nominal 24 V DC supply.

The C version incorporates a coated PCBA for additional protection in harsh environments. With IP67/IP69K ingress protection, an operating temperature range of -40 to +70 °C and a compact 75.2 × 30 × 12 mm housing, Adam C OSSD-Info M12-8 provides a robust non-contact solution for demanding industrial guard-monitoring applications. The Eva actuator is ordered separately.

OSSD Guard Monitoring with Series-Connection Capability

An ABB Eden safety sensor consists of an Adam sensor and an Eva coded actuator. When the guard is closed and Eva is correctly positioned within Adam's sensing zone, the sensor provides its OSSD safety signals. Moving Eva outside the sensing range causes the OSSD outputs to switch to their safe state so that the connected safety system can initiate the required machine response.

A key distinction of the M12-8 OSSD-Info version is its support for series connection, making it suitable for installations where multiple Eden sensors need to be incorporated into the safety architecture. Information functionality on pins 5 and 8 provides additional status signalling, while the coated PCBA of this C variant improves environmental resistance. Compatible Eva General Code and Eva Unique Code actuators are available separately to suit the required coding level.

Typical Applications

• Non-contact monitoring of machine safety doors and gates.
• Guard, hatch and access-panel interlocking.
• Series-connected machine-guard monitoring systems.
• Packaging, processing and material-handling machinery.
• Food and beverage equipment requiring robust ingress protection.
• Automated production and assembly systems using OSSD-compatible safety controllers.
