Honeywell Technologies HDLS Series Roller Lever Limit Switch SPDT 10A 240V AC IP67 Die Cast Zinc Epoxy Coated LS3A3K-7AA

Honeywell LS3A3K-7AA HDLS Series Roller Lever Limit Switch is an industrial-grade mechanical control device engineered for position sensing and safety interlock duties. The compact unit is equipped with a roller lever actuator and a snap-action SPDT contact system. The housing is die-cast zinc epoxy coated to ensure robust protection and durability in demanding environments.

Rated IP67, this limit switch is sealed against dust and water ingress, making it ideal for wet and dirty industrial settings. It supports a switching current of 10A at 240V AC and can handle 24V DC switching in low-voltage control circuits. The device withstands mechanical lifetimes of up to 50 million operations, improving reliability over long-term use.

The switch plugs into control panels via PG13.5 conduit entries accommodating standard conduit glands, and electrical connection is secured with screw terminals, simplifying installation and maintenance.

This limit switch is designed for numerous industrial applications including end-of-travel detection on conveyor systems, actuator position sensing in fabrication machinery, interlock control on automated packaging lines, and limit detection on industrial doors and gates. Its operational temperature range between -12°C and 121°C allows deployment in varied climatic conditions.
