Honeywell HDLS Series Limit Switch, IP67, 10A Switching Current - LS4A3K-1B

This limit switch provides rotary-actuated position detection for industrial control systems. Housed in a die-cast zinc enclosure with ingress protection suitable for harsh environments, it performs discrete switching tasks where a compact, front-mounted actuator is required. The device is built for repetitive mechanical operation and is applicable where snap-action contact behaviour and a simple changeover output are preferred.

Features and Benefits:

• SPDT snap-action contact for clear single-pole switching performance
• Rated for 10A at 240V AC enabling standard mains switching loads
• Switching capability at 24V DC for low-voltage control circuits
• Mechanical life rated to 50 million operations for extended service
• IP67 enclosure resists dust and temporary water immersion
• M20 Terminal entry supports secure glanded cable connections

Applications

• Suitable for conveyor end-of-travel detection on manufacturing lines
• Ideal for valve position monitoring in process plants
• Used with motor starters for limit-based interlocks
• Can be used for door or gate position sensing in access systems

What mounting orientation is required for correct operation?

It is designed for front mounting so the actuator is accessed from the device face during installation.

What operating temperature range can be expected in service?

The unit is specified for use between -12 °C and 121 °C, allowing operation in moderately cold to elevated temperature environments.

How much actuation force is needed to operate the mechanism?

The rotary head requires an operating force of 17.8 N to trip the internal contact mechanism.

What approvals cover electrical safety and market acceptance?

The switch carries CE, CSA and UL approvals, supporting deployment in multiple regulated markets.
