Using the XMR unit, separate key transfer between an (isolation) key switch and key exchange unit is no longer needed, safeguarding potentially dangerous machines and areas with multiple access doors.
By turning the first key of the XMR the safety contacts are broken, isolating the machine power. This key is then trapped and the other access keys can then be used to open the door locks allowing access to the safeguarded areas. Only when all keys are returned to the XMR can the machine be restarted.
The XMR is available in different switch currents and switch contacts.
Besides the standard back of board version an enclosed version (IP67) is available.
The XMR and other Fortress
products are suitable for use in high risk SIL3, PLe and Cat. 4 applications.
