Safety interlock switch

IDEC Corporation's new HS1T interlock switch with solenoid delivers 5,000N of locking force, with many features included to maximize protection in machine and equipment guarding applications. IDEC's HS1T improves performance in a compact size due to a metal head integrating the locking and mounting functions. Also, to maximize 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 various mounting options, the HS1T can be installed virtually anywhere, providing flexibility for designers. IDEC has included three independent rotary cams. Two cams control the locking mechanism and one drives the door monitor contact. This 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. For additional integrity, the lock monitoring contact can never indicate closed if the door is not positively closed, thereby preventing the associated machine from being turned on with risks exposed. The HS1T provides multiple available cable entry ports, with fast and reliable wiring connections made possible by spring clamp terminals. These connections offer vibration resistance, prevent wires from loosening, and never need tightening. Spring lock or solenoid lock styles are available, with several options for contact configurations. These flexible installation options are complemented by an IP67 and Type 4X indoor use only rating. An energy-efficient solenoid consumes 200mA while actuated, reducing electricity costs and allowing controls to activate the device directly without a relay.
