Safety Interlock Switches

Safety Interlock Switch Products

Class 9007 / Refer to Catalog 9007CT0201

XCS Safety Interlock Switches

XCS safety interlock switches ensure that the doors, gates, or guards are closed before a process which could be harmful to personnel can start up. The hazards to personnel can be mechanical, electrical, hydraulic, pneumatic, chemical, or thermal. The Various sizes and shapes of safety interlock switches are designed for a wide variety of applications. These mechanical devices have two components: a switch and an actuating key. When the gate or guard is closed, the actuating key attached to the gate or guard is inserted into the switch, closing the safety contacts, allowing the machine to be started. When the gate or guard is opened, the actuating key is removed from the switch, contacts open the safety switch.
XCS safety interlock switches are designed to meet demanding requirements in the US and Europe, as well as the rest of the world. The flexibility of the XCS line allows one XCS device to perform the same functions as several competitor’s devices. This means that fewer XCS devices may be required to cover your needs.
Specifically designed for the protection of machine operators, maintenance and other personnel, the XCS switches can be used in a wide range of applications where a gate, door or guard is a part of the safety system.
Wide variety of body styles, contact arrangement, and operators meet a variety of application requirements.
Switches are interchangeable between new and older devices, as well as with competitor’s devices.
Pre-wired devices and many connector options available to make wiring and installation easier.

XCSDM Non-Contact Safety Interlock Switches

XCSDM non-contact safety interlock switches are designed for the same functions as mechanical safety interlock switches. The difference is that the non-contact safety interlock switches are magnetically coded devices and require no contact between the switch and coded magnet. This is a benefit where door or guard mis-alignment is an issue, or where the machine designer does not want to use a mechanical device.
Food, beverage and pharmaceutical applications require that no contaminants be trapped in or around devices.
Non-contact devices have no inherent operating force and are well-suited for applications such as lightweight or plexiglass doors, where cracking or breakage is prevalent with standard mechanical safety interlock switches.
Wash down applications where a standard mechanical safety interlock switch would be more difficult to clean, especially in the actuating key receptacle.
Multiple coded-magnet approach directions allow for maximum flexibility of mounting options
Smallest size in the marketplace for Category 4 applications
0.63 x 2 x 0.28 in. (16 x 51 x 7 mm)
