The EKS Light from EUCHNER is a transponder-based access control system consisting of two components: an Electronic-Key with RFID transponder and an Electronic-Key adapter with integral read unit. The EKS Light was designed particularly for smaller, decentralized applications to permit reliable controlled access to individual machines or to entire installations there as well. The new FSA version of the EKS Light was specially developed to solve the widespread problem involving tampering of safety guards.
