Approvals and Markings
Function
Safety switch with forced key inserting and electromechanic blocking of
the key. Only when a signal is connected to the magnet, the key can be
inserted.
Mechanical guard locking with separate actuator and electromechanical
release and optionally removable second key
The first key can only be inserted when the magnet is activated. This
switches the monitoring contacts of the blocking mechanism. With the
introduction of the key the key contacts switch. The actuator and the
second key can then be removed.
TheYRX10B01M/K unit is available in accordance with EN ISO 14119:2013
with low and medium coding level actuators.
The second key can be used as part of a key transfer system or as a
personal key, d. h. as protection against confinement and unexpected
restart can be used. Multiple keys allow the operation of several units
in the system or the protection of several people. For this purpose, the
YRX10B01M/K unit can be extended also above the actuator module or
second key module with additional key modules. The use of personal keys
normally eliminates the need for an escape release (ISO TS19837:2017).
This unit can optionally be equipped with an auxiliary release. Padlock
modules can also be added. The designation of the interlocking modules
with mechanical release is YRH/K module. An emergency release can
consist of safety-related reasons not to be added to these units.
This unit is also available with integrated command functions.
