BERNSTEIN
SRM rope pull switch
The SRM (metal enclosure) safety rope pull switches are available with the Quickfix quick-connect system, which renders unnecessary cable eye stiffeners, cable grips and turnbuckles that are otherwise required for mounting the cable. Added to this, the time required to install the cable is drastically reduced. Versions with a conventional eye are, of course, also available.
All variants of the SRM are equipped 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.
The type SRM...E-... safety rope pull switches are optionally available with a remote indicator for monitoring the cable tension. This option has an integrated sensor unit that monitors situations in which the cable tension may overshoot or undershoot the permissible value, or triggering of the safety rope pull switch is imminent.
- 4 contacts, 2 NC+2 NO default, all options available
- Rope length capabilities between 1-75 metres
- Wire tension indicator, integrated inspection window
- Integrated emergency stop button
- Wire quick fix (QF versions)
