Honeywell HDLS Series Limit Switch, 10A Switching Current, IP67 - LS3A3K-7AA


This limit switch is a Compact mechanical control device designed for position sensing and safety interlock duties in industrial environments. It operates via a roller lever actuator to detect movement or presence of components and provides a single-pole double-throw switching output for circuit control. The product is built for use where a sealed enclosure, moderate switching capacity and straightforward wiring are required.

Features and Benefits:


• Die-cast zinc housing for robust mechanical protection and durability
• IP67 ingress rating to permit use in wet or dusty conditions
• Snap-action SPDT contacts delivering quick, definitive switching response
• Screw terminals for secure, maintenance-friendly electrical connections
• 10A switching at 240V AC to handle common control loads
• Mechanical endurance rated to 50 million operations for long service life

Applications


• Suitable for end-of-travel detection on conveyor lines
• Ideal for actuator position sensing in fabrication machinery
• Used for interlock control on automated packaging equipment
• Can be used for limit detection on industrial doors and Gates
• Suitable for integration into control panels requiring sealed switches
