Sealed emergency stop switch simplifies installation with M12 connectors

RAFI has expanded its RAMO series product offering to include emergency stop switches (E-Stop) for rugged applications, complementing the previously released RAMO pushbuttons and signal Indicators. The RAMO Series pushbutton control components feature fully enclosed mono-housings with ingress protections of IP65, IP67 and IP69K, and standard M12 plug and play connectors. This ensures that the necessary wiring effort is reduced to a minimum and that no extra enclosures with special sealing are required.

Emergency stop switches, or E-Stops, are critical system components that protect= the safety of both operators and machinery in a variety of emergency shut down situations. Depending on a customer's end product and market, E-Stops are regulated by a large range of international safety standards that cover both the performance specifications of the switch, and the need for an E-Stop on equipment and machinery.

"The largest cost driver for installing industrial controls into a typical application is not the cost of the switches and components, but rather the labor required to manually wire each component, and time preparing the custom enclosure. This was necessary in the past because control elements were designed for manual wiring and housing integration exclusively and all connections required extra protection from moisture and dirt — usually by means of expensive NEMA enclosing solutions," said Gary Mountford, VP of Components for RAFI-USA. "The RAMO series E-Stop switches simplify installation and save time via the M12 plug-and-play connection that eases assembly and is sealed above and below the mounting surface."

If there are very tight space restrictions, installers can use M12 connectors featuring right-angle cable exits. Rotated by 135°, the cable exits allow for a high packing density. The RAMO Series E-Stop switch has 2NC contact capable of switch 35V, and are available in both 22MM and 30MM versions, and meet applicable ISO and IEC standards.
