ABB Eva actuator with unique code

Why Choose the ABB Eva Unique Code Actuator?

The ABB Eva Unique Code is a compact non-contact safety sensor actuator designed for use with ABB Jokab Safety Adam DYN and Adam OSSD sensors in the Eden safety sensor system. Identified by ABB order code 2TLA020046R0900, Eva provides the coded target detected by the Adam sensor for safety interlocking of machine guards, doors and hatches, as well as safe-position monitoring.

Unlike the interchangeable Eva General Code actuator, the Eva Unique Code uses a unique high-level code intended to provide increased protection against deliberate defeat or substitution of the safety device. When paired with a compatible Adam sensor, it forms a high-level coded non-contact safety sensor. ABB documentation identifies the unique-code version as suitable where increased coding protection is required in accordance with the principles of EN ISO 14119.

The actuator operates without mechanical contact with the Adam sensor, eliminating contact wear during normal operation. With a typical operating distance of 15 mm, compact 60 × 30 × 12 mm dimensions and IP67/IP69K protection, the Eva Unique Code is well suited to demanding industrial machine-safety applications. Four DA 2B spacer rings are supplied with the actuator to assist installation.

High-Level Coded Non-Contact Machine Safety

The ABB Eden system consists of an Adam sensor and an Eva actuator. Eva is normally mounted to the movable machine guard while Adam is mounted to the fixed structure. When the guard closes and the uniquely coded Eva enters Adam's sensing area, the sensor recognises the actuator without requiring physical contact between the two components.

The key difference between this actuator and the Eva General Code is the coding level. Eva General Code actuators are interchangeable and provide low-level coding, while the Eva Unique Code provides high-level coding intended to reduce the possibility of defeating the interlocking system using another readily available actuator. This makes the unique-code version particularly suitable where a machine risk assessment identifies increased protection against manipulation as necessary.

Typical Applications

• Industrial machine guard monitoring.
• Safety doors and access gates.
• Robot cell guarding.
• Machine access hatches and panels.
• Packaging and processing machinery.
• Assembly and automated production equipment.
• Safe-position monitoring applications.
• Applications requiring high-level coded guard interlocking.
