LP28 2-Pin 50A Waterproof Power Connector

LP28 2-Pin 50A Waterproof Power Connector – High-Current Field-Wired Connection with IP67 Sealing

Fifty amps through two pins. That's not a connector you buy by the dozen and hope for the best. The LP28 2-Pin 50A Waterproof Power Connector is built for that load — 10mm² cable, 500V, IP67 sealed, and screw terminals you tighten with a screwdriver on site. Two poles, one job: move serious current through a connection that gets wet and gets wired in the field.

LP28 2-Pin 50A Waterproof Power Connector – The Big-Cable Problem Fifty Amps Creates

Here's what fifty amps does. It forces 10mm² cable, which is stiff, hard to bend, and puts real torque on whatever coupling you thread it into. Most connectors at this current level either need crimped lugs or come with hardware that strips out after a few installs. The LP28 2-Pin 50A Waterproof Power Connector uses a metal coupling thread for exactly that reason — it takes the torque without giving up. Plastic everywhere else to keep the weight sane.

Screw terminals handle the termination. Strip the 10mm² cable, insert it, tighten. No crimping tool, no lug, no calibrated die. The cable gland anchors the wire separately from the contact points, so pull force never reaches the terminals. Cable entry takes 16.5 to 18.5mm outer diameter.

Built for Wet, Rough, Industrial Environments

IP67 sealing holds up to rain, washdown, and short-term immersion. Not IP68, and that's a deliberate spec — IP67 is what most field power applications actually need, and it keeps the cost where it belongs. The housing is metal on the coupling thread where the wear happens, plastic elsewhere.

We've seen these end up on industrial motors, generator hookups, welding equipment, EV charging gear, and marine shore power. Places where you've got fifty amps running through one connection and a wet floor underneath.

Technical Specifications at a Glance

Where This 50A Connector Actually Gets Used

High-current runs in wet environments. Industrial motor hookups. Generator output connections. Welding equipment leads. EV charging station wiring. Marine shore power. Construction site distribution. Anywhere you need fifty amps through a connection that gets wired on site and left alone — and that's where the LP28 2-Pin 50A Waterproof Power Connector ends up.

Every batch gets a dielectric test and a waterproof check. Screw terminals get torque-checked, not just eyeballed. It costs us time. It saves you callbacks.

Quality Control and Certifications

The LP28 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: Why IP67 instead of IP68?

A: IP67 covers rain, washdown, and short-term immersion — which is what most 50A field power applications actually see. IP68 would add cost for continuous submersion, and that's overkill here. If you need IP68 for a specific job, talk to us.

Q: What cable size does it take?

A: 10mm² with a 16.5 to 18.5mm outer diameter. That's the class of cable you need for fifty amps anyway.

Q: Why screw terminals instead of crimped lugs?

A: Field wiring. Crimped lugs need a calibrated tool and the right die. Screw terminals need a screwdriver. Same current rating, less gear to bring.

Q: Can I re-terminate in the field?

A: Yes. Loosen the screw, adjust, re-tighten. No wasted lugs, no wasted connector.
