Discontinuation Notice: Replace HS1E Safety Interlock Switches with HS1L: Stronger with more contacts!
IDEC is discontinuing the HS1E series of Safety Interlock Switches effective immediately. Orders will continue to be accepted as long as we have remaining inventory. As a replacement to these we recommend upgrading to the HS1L series where alternate part numbers are relevant, our website has been updated with the proper cross reference.
While this series is similar to the HS1E interlock safety switches, HS1L has additional features including six contacts (HS1E only had 3-5) with easy-to-wire termination and increased locking strength of 3,000N (HS1E only had 1500N). That is twice the locking strength of standard competitor switches of this size.
HS1L is designed to work in applications with large machines that have heavy doors or gates and is equipped with a manual lock-release key and an LED indicator. The indicator is wired independently, for added flexibility. Screw terminals are also easy to wire. No barriers on the sides of the contact terminal enable wiring from the side. And unlike competitors' safety switches, HS1L has a significant height difference at contact terminals making it easier for crimp-terminal connections as well.
Note: HS1E and HS1L have the same dimensions and mounting orientation. However HS1E uses HS9Z-A1/A2/A3 actuators, while HS1L uses HS9Z-A1S/A2S/A3S actuators. Also, HS1E uses an M3.5 type terminal screw, while HS1L uses an M3 type.
