l All variants of the SRM and especially of the SR are equipped
l The type SRM...E-... safety cable pull switches are optionally
Overview 1
The parameter 100, 175 and 300 in the product designation indicates the force of the springs used in the
cable pull switch. It should be noted that a grater actuating force is required for higher spring forces.

safety cable pull switches are available with the Quickfix
quick-connect system, which renders unnecessary cable
eye stiffeners, cable grips and turnbuckles that are other-
wise required for mounting the cable. Added to this, the
time required to install the cable is drastically reduced. Ver-
sions with a conventional eye are, of course, also available.
with an integrated emergency stop impact button that can be
actuated by pressing in hazardous situations. In the same way
as pulling the pull cable, the safety contacts are opened and
the switch is locked.
available with a remote indicator for monitoring the cable
tension. This option has an integrated sensor unit that mo-
nitors situations in which the cable tension may overshoot or
undershoot the permissible value or triggering of the safety

and of the contacts. Yellow in the inspection window indicates
that the safety cable pull switch is locked. Green in the inspec-
tion window indicates that the cable pull switch is ready for
operation and the cable assembly is monitored.
