LP24 5-Pin Screw Lock Circular Connector

LP24 5-Pin Screw Lock Circular Connector – 20A Five-Pole Connection with IP68 Sealing

Five wires going into a wet, shaking piece of equipment. That's where the trouble usually starts. The LP24 5-Pin Screw Lock Circular Connector is built for that setup — 20A per contact at 400V, screw terminals you tighten on site, and IP68 sealing that handles water. Five poles for three-phase plus N and PE, or four circuits plus a return. One job: get all five lines in and out without a mix-up.

LP24 5-Pin Screw Lock Circular Connector – The Wiring Problem Five-Pole Equipment Runs Into

More wires means more chances to get it wrong. Five-pole gear — three-phase plus N and PE, or four DC circuits with a shared return — usually gets wired on site, by whoever's available, with whatever tools are in the van. The LP24 5-Pin Screw Lock Circular Connector keeps that from turning into a service call. Screw terminals, not crimped. Strip the wire, push it in, tighten. The clamp holds 2.5mm² (14 AWG) cable tight, and the cable gland takes the pull so the contact points don't have to.

A five-pole cable is thicker and stiffer than a three-pole. That puts more torque on the coupling when someone overtightens it. The metal thread on this connector handles that load. Plastic everywhere else to keep the weight down.

Where Five-Pole Equipment Gets Wet

Five-wire gear tends to live outdoors or in washdown areas — small three-phase pump controls, outdoor HVAC units, multi-circuit irrigation panels. These are the places water finds a way in. The LP24 5-Pin Screw Lock Circular Connector runs IP68 at 2 meters for 24 hours. Cable entry takes 2.5mm² (14 AWG) wire with a 14mm outer diameter.

Nothing fancy here. Just a seal that holds and a housing that doesn't crack when the temperature swings between -40℃ and +85℃.

Technical Specifications at a Glance

Where This 5-Pin Connector Actually Gets Used

Small three-phase pump controls with neutral and ground. Multi-circuit DC panels. Outdoor HVAC control boxes. Agricultural irrigation controllers. Marine power distribution. Construction site distribution units. Anywhere you've got five lines running into equipment that gets wet — and that's where the LP24 5-Pin Screw Lock Circular Connector ends up.

Each production batch goes through a phase-to-phase insulation test, plus the usual dielectric and waterproof checks. Five poles means more paths for a fault to hide, so the testing takes longer on this one than on our 2-pin and 3-pin versions. Worth it.

Quality Control and Certifications

The LP24 series carries TUV, CE, and RoHS. We run ISO9001:2015, so material sourcing is consistent and production records are traceable. And the quality system actually gets audited — not just claimed.

Quick Questions We Get Asked

Q: What's the 5th pin for?

A: Depends on the setup. Three-phase plus N and PE is the most common. Or four DC circuits with a shared return. Or three power lines and two control lines.

Q: How do I keep from miswiring five poles?

A: Label the wires before you start, and use the keyway on the housing to orient the connector the same way every time. Five poles is where mix-ups happen most.

Q: Why screw terminals instead of solder?

A: Field wiring. Not every job site has a soldering iron. Screw terminals let you terminate 2.5mm² cable with a screwdriver, and the clamp holds tight under vibration.

Q: Can it stay submerged?

A: Yes. IP68 covers continuous immersion. We test at 2 meters for 24 hours.
