Cable-Operated Switches
3SE7 1.0 / 3SE7 310
Molded plastic / metal enclosure
Application
Cable-operated switches are
used for monitoring or for EMERGENCY-STOP facilities on particularly endangered system
sections. They are available with
metal enclosures.
Principle of operation
The switch contacts of the cableoperated switches and the conveyor belt unbalance protection
devices are positive opening.
As the effective range of a cableoperated switch is limited by the
length of the pull-wire, large systems can also be protected.
Cable-operated switches (requiring pulling at both ends) and
conveyor belt unbalance trackers are used primarily for
monitoring very long belt systems.
Specifications
Switches with latching for implementation in EMERGENCYSTOP equipment correspond to
the EN 418 standard.
Cable-operated switches with
one-side operation are held in
free position by the pre-tension
force on the turnbuckle.
• In the 3SE7 140, -150 and -160
cable-operated switches, both
switching contacts are available for cable-break/cable pull
signaling. The NO contact is
used, for example, for signaling purposes.
For switches with latching, with a
pretensioned cable, the locking
must be deactivated beforehand
in order to return the switch to its
free position.

Application: Conveyor belt monitoring
Rope Pull Switches might be
used as Emergency-STOP
devices to cover a continuous
distance for immediate shut-off
instead of using common ESTOP pushbutton devices.
SIGUARD rope pull switches
with latching meet the
requirements according to
EN418 and provide NC contacts
with direct opening action.
Rope pull switches without
latching can only be used as
normal stop devices.
SIGUARD Rope Pull switches
• trip due to a pulled and a broken rope
• are equipped with a manual reset to close NC contacts after
retensing the rope
• can be mounted in any direction
• cover different rope lengths up
to 50m
• support a whole range of accessories and mounting equipment
• shall be used with the offered
steel rope with red plastic coating
