Honeywell HDLS Series Rotary Head Limit Switch, SPDT, IP67, Die Cast Zinc Epoxy Coated Housing, 240V AC LS4A3K-1B

Honeywell LS4A3K-1B HDLS Series Rotary Head Limit Switch is engineered for precise rotary-actuated position detection within industrial automation and control systems. Housed in a robust die cast zinc epoxy coated enclosure with an IP67 ingress protection rating, this device offers excellent resistance against dust and temporary water immersion, making it suitable for harsh industrial environments.

Equipped with a SPDT snap-action contact, the switch delivers reliable single-pole switching performance with a switching current capacity of 10A at 240V AC, enabling it to handle standard mains electrical loads efficiently. It also supports switching at 24V DC for integration into low-voltage control circuits.

Designed for long-term durability, the mechanical life expectancy is rated to 50 million operations, ensuring minimal maintenance and downtime. The switch features an M20 terminal type for secure, glanded cable terminations, enhancing safety in wiring installations.

The rotary head actuator is mounted frontally for easy access and requires an operating force of 17.8 N to actuate the internal contact mechanism safely. This product operates effectively within a temperature range of -12°C to 121°C, allowing deployment in diverse climates and process environments.

It carries key electrical safety approvals, including CE, CSA, and UL certifications, making it compliant for use in multiple regulated markets. The compact size with precise dimensions (Length 106.7mm, Width 41.1mm, Depth 62mm) facilitates installation in constrained spaces such as conveyor ends, valve position monitoring setups, motor starter interlocks, and door or gate position sensing systems.
