Approvals and Markings

Function

MK11M: After the first key has been inserted at the top, the second key
must be removed before the actuator can subsequently be removed.
M11A and M11BM: After inserting the first key at the bottom, the second
key must be removed before the actuator can be removed.
With the M11A version, actuators can be inserted both laterally and from
above into the actuator module . The coding level of the associated actu-
ator according to EN ISO 14119:2013 is low.
The M11BM and MK11M versions offer increased stability of the actuator
module. It is also available in accordance with EN ISO14119:2013 with
actuators for low and medium coding levels. The second key can be used
as part of a key transfer system or as a personal key, i. e. be used as pro-
tection against confinement and unexpected restart. Multiple keys allow
the operation of several units in the system or the protection of several
people. For this purpose, the M11BM unit can also be extended above the
actuator module with additional key modules. The use of personal keys
normally eliminates the need for an escape release (ISO TS19837:2018).
The MK11M variant is particularly suitable for applications in which the
actuator must be mounted below the unit for ergonomic reasons or for
design reasons.
Optionally, this unit can be equipped with padlock modules, electrical
monitoring contacts or an electromechanical release.
