IDEC HS1T safety interlock switch

IDEC Corporation has released its HS1T interlock switch with solenoid, which provides 5000 N of locking force, with many features included to maximise protection in machine and equipment guarding applications.

The high locking force of the HS1T is achieved in a compact size due to a metal head integrating the locking and mounting functions, an improvement over older designs where the head could break away from the mounting body. Also, to maximise installation options, the remaining actuator portion can be independently rotated from the high-strength head using only one screw. With a slim form factor and so many mounting options, the HS1T can be installed virtually anywhere, providing greater flexibility for designers.

IDEC has also included three independent rotary cams, instead of the single cam used by conventional devices. Two cams control the locking mechanism and one drives the door monitor contact. This arrangement provides redundancy, additional strength and ensures the monitoring function continues to work even if a locking cam is damaged.

The HS1T meets the requirements of ISO 14119:203 for Lock Monitoring and is marked as such. This means both the status of the position and the locking function of a protective door can be monitored through the lock monitoring contact.

There are also multiple cable entry ports, with faster and more reliable wiring connections made possible by spring clamp terminals. Designers can choose from spring lock or solenoid lock styles, with several options for contact configurations, as well as IP67 and Type 4X indoor-use-only ratings.
