XCS-DM non-contact safety interlock switches perform the same functions as standard mechanical safety interlock switches, but are designed to be used where no contact is desired between the switch and its actuating key.

Non-contact safety interlocks are designed for use in applications where the stopping time of the hazardous area is shorter than the access time of the operator opening the guard and reaching in. These devices are recommended for applications with little or no shock or vibration, where there is minimal chance of the door or guard opening unintentionally.

There are several reasons for using a non-contact type of device:

• Food and beverage and pharmaceutical applications require that no contaminants be trapped in or around devices.
• Applications demanding zero operating force, such as lightweight or plexiglass doors, where cracking or breakage is possible with standard mechanical safety interlocks. Non-contact devices have no inherent operating force.
• When there are alignment issues with the switch and actuating keys of 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.
