IP67 limit switch w/side roller plunger

Honeywell Series LS Limit Switch, 6A Switching Current, IP67 - 3LS1-4C

This limit switch is a compact, actuator-equipped device designed to detect mechanical movement and provide discrete electrical switching in industrial control systems. It is built for panel mounting and suited to environments where a robust plunger-operated sensor is required for position or safety interlock functions.

Features and Benefits:

• SPDT double-break contact for reliable circuit changeover performance
  IP67 environmental sealing enabling use in wet or dusty conditions
  Die-cast zinc housing offering Durable mechanical protection
  Screw terminals for secure electrical connections under vibration
  Switching capability at 6A for AC loads up to 240V
  Operating force 40.1N to ensure consistent actuation response

Applications

• Suitable for conveyor end-of-travel detection in automation lines
  Ideal for machine guard interlocks in manufacturing plants
  Used with hydraulic presses for position sensing and control
  Can be used for lift door position monitoring systems

What conduit options exist for wiring the device?

It accepts a 0.5–14 NPT conduit entry allowing standard threaded conduit connections for routed cabling.

How does the switch perform across temperature extremes?

It operates across a range from −29°C to 71°C, maintaining contact and sealing performance within those limits.

What Terminal and contact voltages are supported for DC applications?

The screw terminals accommodate switching of DC circuits up to 250V with the double-break contact arrangement.

What mounting orientation is required during installation?

It is intended for panel mounting to provide secure attachment and correct plunger alignment with actuating mechanisms.
