LP20 2-Pin Screw Lock Waterproof Connector
2. Screw terminals — strip, insert, tighten. No crimping tool needed on site.
3. Hybrid metal-plastic shell. Metal thread for durability, plastic body to keep weight down.
4. IP67 sealed when mated. Rain, washdown, wet floors — no problem.
5. Takes 2.5–4mm² cable (14–12 AWG) with an 8–12mm outer diameter.
6. 2500V withstand voltage. Plenty of safety margin for industrial power.
7. Re-terminate in the field anytime. Loosen the screw, adjust the length, re-tighten — no wasted connector.

LP20 2-Pin Screw Lock Waterproof Connector – High-Current Power Connection with Tool-Free Wiring
We build industrial waterproof connectors for a living, so we know what electricians and field techs actually want. The LP20 2-Pin Screw Lock Waterproof Connector is made for equipment that draws serious current — think 20A at 500V — where you need a connection that won't loosen, won't leak, and won't require a crimping tool to install. The hybrid metal-plastic shell handles mechanical abuse, and the screw-lock terminals mean you can wire it on site with nothing more than a screwdriver.
LP20 2-Pin Screw Lock Waterproof Connector – Built for High-Current, Field-Wired Installations
Here's something installers ask us all the time: how do you hook up 12AWG cable in a waterproof connector without hauling a crimper out to the job site? The LP20 2-Pin Screw Lock Waterproof Connector handles it. Strip the wire, push it in, tighten the screw — that's it. The screw clamp holds 2.5 to 4mm² cable tight, and the built-in cable gland keeps pulling force off the electrical contact where it belongs.This is a 20A-rated connector with a 500V working voltage and 2500V withstand rating. That's enough headroom for motors, pumps, heaters, and industrial power distribution. The IP67/IP68 seal holds up in washdown areas, outdoor cabinets, and wet industrial floors.
Why Screw Lock Beats Crimp in the Field
Crimped connections are great — when you're in a factory with the right tool sitting on the bench. Out in the field? Not so much. Someone forgets the crimper, or the die is worn, or the guy doing the wiring hasn't been trained on that particular tool. That's exactly why the LP20 uses screw-lock terminals. Strip the wire, tighten the screw, done. The connection quality depends on your hand, not on whether someone remembered to pack the right gear.You torque it down, it stays down.
The hybrid shell — metal front, engineering plastic body — gives you a good balance. You get the impact resistance and thread durability of metal where the coupling happens, and you keep the weight and cost reasonable. The 12mm cable entry handles power-class cable diameters from 8 to 12mm.

Where This Connector Actually Gets Used
The LP20 2-pin shows up where high current meets wet or dirty conditions. Industrial motors and pumps. Outdoor HVAC units. Construction site power distribution. Electric vehicle charging equipment. Marine shore power connections. Anywhere you need to run 20 amps through a connection that gets installed in the field, not on a factory bench.
We test every batch for dielectric strength and waterproof performance. The screw terminals are torque-verified, not just visually checked. It takes extra time, but it keeps callbacks off your schedule.
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 re-terminate this connector in the field if I need to change cable length?
A: Yes. Loosen the screw, pull the wire, cut to length, re-insert, and re-tighten. No crimping tool, no wasted connector.
Q: What cable sizes does it accept?
A: 2.5 to 4mm² (14-12 AWG) with a cable outer diameter of 8-12mm. That covers most power-class installations.
Q: Is this suitable for outdoor use?
A: Yes, when mated it holds IP67/IP68. The threaded coupling resists vibration, and the seal keeps water out in rain, washdown, and temporary submersion.
Q: Does the screw lock loosen under vibration?
A: We've tested it on motors and pumps. The screw clamp holds torque well, and the threaded coupling keeps the housing locked. If you're running high-vibration equipment, this is a better choice than snap-lock.
