Honeywell HDLS Series Limit Switch, 20mm Conduit Entry, Die Cast Zinc Housing - LS4A3K-2B
This limit switch provides electromechanical position detection for industrial automation and control systems, using a roller-actuated lever to convert mechanical movement into an electrical change. It is designed for harsh environments where robust enclosure protection and reliable switching are required, fitting installations that need a compact, conduit-ready actuator with snap-action contact behaviour.
Features and Benefits:
• Die-cast zinc housing offering enhanced mechanical protection for installations
• IP67 ingress protection enabling operation in dusty or water-exposed locations
• SPDT snap-action contacts delivering fast state change and predictable switching
• Rated switching capacity of 10A at 240V AC for substantial load handling
• Mechanical endurance of 50 million operations reducing maintenance frequency
• Operating temperature range supporting use up to 121°C for high-temperature tasks
• IP67 ingress protection enabling operation in dusty or water-exposed locations
• SPDT snap-action contacts delivering fast state change and predictable switching
• Rated switching capacity of 10A at 240V AC for substantial load handling
• Mechanical endurance of 50 million operations reducing maintenance frequency
• Operating temperature range supporting use up to 121°C for high-temperature tasks
Applications
• Suitable for conveyor end-of-travel detection in manufacturing lines
• Used for limit sensing on industrial presses and machine tools
• Ideal for position feedback on robotic pick-and-place mechanisms
• Can be used for gate or hatch position monitoring in outdoor installations
• Used with control panels requiring a Compact switch with conduit entry
• Used for limit sensing on industrial presses and machine tools
• Ideal for position feedback on robotic pick-and-place mechanisms
• Can be used for gate or hatch position monitoring in outdoor installations
• Used with control panels requiring a Compact switch with conduit entry
What conduit size does it accept for cable entry?
It accepts an M20 conduit entry allowing standard industrial gland fittings.
How does the actuator type affect mounting versatility?
The adjustable roller lever enables alignment with various cam profiles and travel directions to suit differing mechanical linkages.
What electrical connection style is provided for wiring?
Termination is via a Terminal designated M20 for secure cable or gland attachment in control enclosures.
How Compact is the unit for constrained panel spaces?
The unit has a length of 106.7mm and width of 41.1mm, allowing fitting into confined assemblies without an excessive footprint.
