The following switches are ”taut cable” style with positive break and positive transfer features which make them particularly competent for Emergency Stop applications as well as ordinary circuit control.
They are only offered in manual reset configuration with 2 NO + 2 NC gold plated contacts. The housing is made from high quality die-cast aluminum and painted with a yellow dry powder paint. Set-up position is easily attained without removal of the cover. Cable is stretched tightly until shaft end is flush with indicator hub end. Switch will trip and latch if the cable breaks, comes loose or is pulled. Blue booted reset button is pushed to reset contacts back to their normal operating configuration. These switches have been designed to reduce “nuisance tripping” from cable expansion and stretch often associated with taut cable switches.
The mounting pattern coincides with other standard REES cable switches. Additional mounting holes are provided to match competitive devices. Direction of pull is field convertible. Three 1/2" NPT conduit openings are provided. Maximum recommended cable length is 200 feet with a maximum interval support of 10 feet. The maximum mechanical life of these devices is 250,000 operations.
These switches are typically found on process applications such as conveyors, transfer machines or assembly lines within the automotive, machine tool, foundry and pharmaceutical industries. Switches are rated NEMA 12/13; IP 65. Their rugged construction and long term reliability make them well suited to function within various industrial environments.
