IDEC safety interlock switches perform the same functions as standard mechanical safety interlock switches, but are designed to be used in applications where no contact is desired between the switch and its actuating key, and space is at a premium.
The HS7A-DMP interlock safety switches have up to three contacts and provide a highquality, space-saving product at a competitive price. The auxiliary contacts enable PLCs to monitor the door status as operation signals can be read directly by controllers.
Category 4 and PLe compliant, the HS3A non-contact RF1D safety switches ensure detection of slow-moving, open, sliding and rattling doors. Multicode and unicode sensor heads are available, preventing tampering with the use of an unassigned spare actuator, and allowing installation in five directions. Designed for use in areas where a high level of tamper resistance and safety is required, HS3A is suitable for almost anywhere where safety and reliability is of the utmost concern.
