HS1L series has increased locking strength of 3,000N and offer six contacts with easy-to-wire termination. HS1L is designed to work in applications with large machines that have heavy doors or gates and all models are equipped with a manual lock-release key and an LED indicator. The indicator is wired independently, for added flexibility and use. Screw terminals are also easy to wire. No barriers on the sides of the contact terminal enable wiring from the side making it easier for crimp-terminal connections as well.
