LineStrong2
LineStrong2 is a robust switch that can handle wires up to 80 meters on a single switch (100 meters on two
switches). When someone pulls the wire of LineStrong2 or if the wire is broken, the switch goes to a safe
state, e.g. the machine is emergency-stopped. After a emergency stop the LineStrong2 needs to be reset to
be able to run again and this is made with the local reset button. Additional features on the LineStrong2 are
a "normal" emergency stop that is fitted on the side of the grab wire safety switch and also a two coloured
LED for indication. LineStrong2 is equipped with an indication of how taut the wire is, which make the
installation and adjustment easy.
Depending on the environment where the switch will be used, different material can be chosen for the
LineStrong2. The basic version has a rugged yellow die cast housing with a rating of IP67. In severe
applications as for food processing and chemical industry there is a LineStrong2Z with a total rugged
stainless steel 316 body. This version has IP69K enclosure protection (maintained by a double seal lid gasket
and seals) and can be high pressure hosed with detergent at high temperature.
A positive forced connection provides a forced disconnect of the safety contacts when the wire is being
pulled or broken. The design of the LineStrong2 ensures that the contacts will not fail or be held in a
normally closed position, due to failure of the spring mechanism or that welding/sticking of the contacts
can occur. The LineStrong2 switch has 2NC and 2NO contacts.

We recommend installing the eye bolts across the whole length of the rope between the switches at min.
2.5 m to max. 3 m. If this cannot be achieved, please see "Distance between eyebolts".
