Honeywell Technologies LS Series Plunger Limit Switch, SPDT, IP67, Die Cast Zinc Housing, 240V AC, 6A 3LS1-4C

Honeywell 3LS1-4C LS Series Plunger Limit Switch is a precise and reliable industrial limit switch designed for automation and control systems requiring robust position sensing and electrical switching.

The device is equipped with a plunger actuator for detecting mechanical movement. Its single-pole double-throw (SPDT) configuration with double break contact ensures reliable circuit changeover performance in both AC and DC applications.

Constructed with a die cast zinc housing, this limit switch offers excellent mechanical durability and protection. The IP67 rating certifies that the switch is dust-tight and protected against immersion in water, making it suitable for harsh and wet environments.

The switch supports switching currents of up to 6A at voltages up to 240V AC and 250V DC. Screw terminals provide secure and vibration-resistant electrical connections, essential for industrial operations.

It can be mounted on panels, facilitating easy and secure installation with consistent actuator alignment for reliable operation. With an operating temperature range from minus 29°C to plus 71°C, it maintains performance throughout temperature extremes encountered in industrial settings.

Typical applications include conveyor end-of-travel detection, machine guard interlocks in manufacturing plants, hydraulic press position sensing, and lift door position monitoring systems.

Other notable features include a 20 mm conduit entry for standard industrial cabling and an operating force of 40.1N to ensure consistent mechanical actuation response. This limit switch features a plunger actuator type for precise mechanical movement detection.

It provides a single-pole double-throw (SPDT) double-break contact arrangement. The die cast zinc housing ensures durable mechanical protection. Rated for switching current up to 6A and supports switching voltages of 240V AC and 250V DC.

Designed for panel mounting with screw terminal connections for secure wiring under vibration. IP67 ingress protection guarantees reliable operation in wet and dusty industrial environments. Works within an operating temperature range of -29°C to +71°C, maintaining performance over temperature extremes.

Suitable for automation conveyor end-of-travel detection and safety interlock systems in manufacturing plants. Conduit entry of 20 mm supports robust industrial cable installation. Operating force of 40.1N ensures consistent actuation response during mechanical switching.
