LineStrong3
LineStrong3 is a quite robust switch that can handle long wires, up to 200 meters on a single switch. When
someone pulls the wire of LineStrong3 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 LineStrong3 needs to be reset to be able to run
again and this is made on the local reset button. Additional features on the LineStrong3 is a "normal"
emergency stop fitted on the top of the grab wire safety switch and also a two-coloured LED for indication.
LineStrong3 is equipped with an indication of how taut the wire is, which makes the installation and
adjustment easy.
Depending on the environment where the switch will be used, different materials can be chosen for the
LineStrong3. 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 LineStrong3Z 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 LineStrong3 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 LineStrong3 switch has 4NC and 2NO contacts.
Single wire - LineStrong3L/3R and LineStrong3LZ/3RZ
The Linestrong3L/3R are two different versions depending on installation.
L - "Left hand" - is the version of LineStrong3 where the placement of the grab wire switch is to the left in
the installation.
R - "Right hand" - is the version of LineStrong3 where the placement of the grab wire switch is to the right in
the installation.
LineStrong3L/3R have die-cast housings and are robust to manage severe indoor or outdoor use.
LineStrong3L/3R are designed to protect a length up to 100 meters on a single switch. If two switches are
used together, up to 125 meters.
LineStrong3LZ/3RZ are in stainless steel 316 housings and are designed specifically to withstand the tough
environments found in the food and pharmaceutical industries. LineStrong3LZ/3RZ are designed to protect
a length up to 100 meters on a single switch. If two switches are used together, the wire can go up to 125
meters.
