LP20 5-Pin Circular Aviation Connector

LP20 5-Pin Circular Aviation Connector – Screw-Terminal Connection for Power and Signal

We've been building industrial connectors long enough to tell the difference between one that looks tough and one that actually makes it through a season on site. The LP20 5-Pin Circular Aviation Connector is the second kind. Screw-lock terminals instead of crimped contacts — so you can wire it in the field with a screwdriver, and it'll still take vibration, moisture, and repeated plugging without giving out. Five pins give you room to work — power on a few lines, signal on the rest, or whatever split your equipment calls for.

LP20 5-Pin Circular Aviation Connector – Built for Field Wiring Without the Toolbox

Here's a question we get from installers all the time: why do so many circular connectors still need a crimping tool and a trained hand? The LP20 5-Pin Circular Aviation Connector does away with all that. Strip the wire, push it in, tighten the screw — that's it. The clamp grips 1 to 1.5mm² cable tight, and the cable gland takes the pull so the contact doesn't have to.

Five pins work well when power and control share the same cable. Run 10A per contact at 250V on the power lines, and use the rest for signal or switching.Or split it however your system needs. The screw terminals stay put under vibration — we've tested them on motors and pumps, not just on a lab bench.

Why Screw-Lock Terminals Make Sense Outside the Factory

Crimped connections are great when you're at a bench with the right die and a calibrated tool. In the field, things are different. Someone forgets the crimper, the die wears out, or the tech hasn't been trained on that specific tool. Screw-lock terminals take that variable out of the equation. You're relying on your hand and a screwdriver — nothing else.
The housing mixes metal and plastic: metal where the threads take the wear, plastic to keep the weight down. Sealing is IP67, so rain, washdown, and wet factory floors aren't a problem. Cable entry is 12mm, which takes power cable with an 8 to 12mm outer diameter, or smaller signal cable from 5 to 6.5mm.

Technical Specifications at a Glance

Where This Aviation Connector Actually Gets Used

The LP20 5-pin shows up in applications where power and control travel together. Industrial control panels. Motor junction boxes. Outdoor lighting arrays. Pump stations. Agricultural equipment. Stage and event power distribution. Anywhere you need five lines running through a connection that gets wired on site and then left alone for years.

We test every batch for dielectric strength and waterproof performance. The screw terminals get torque-checked, not just eyeballed. It takes longer, but it keeps field failures off your desk.

Quality Control and Certifications

The LP20 series carries TUV, CE, and RoHS certifications, and we operate under ISO9001:2015. Consistent material sourcing, traceable production records, and a quality system that gets audited — not just claimed.

Quick Questions We Get Asked

Q: Can I run both power and signal on the same 5-pin connector?

A: Yes. The 5-pin layout handles 10A per contact at 250V, so you can run power on some pins and low-voltage signal on the others — or split it however your setup needs.

Q: What cable sizes does it accept?

A: 1 to 1.5mm² (18-16 AWG) for signal-class cable, or larger power cable with an outer diameter of 8 to 12mm.

Q: Do I need any special tools?

A: A screwdriver and a wire stripper — that's it. No crimping tool, no calibration, no training course.

Q: Is IP67 enough for outdoor use?

A: For most outdoor installations, yes. IP67 handles rain, splashing, and temporary immersion. For continuous submersion, our IP68-rated variants are available.
