Review: Awesome product far better construction than the "Name Brand" units. - I have been using a similar product from a well known manufacturer for more than 20 years and paying almost 5x the price for a lower quality product. As part of my job (now retired) I needed to make instrumentation connections for temporary installations and used a brand name M12 4 pin connector with all the wonderful IEC ratings to do this. Work paid for them so I always got what I thought was the best. Over the years several of these (when I was scrapping out installations) found their way home and I used them for various inhome projects. Overall M12 connectors are awesome and very versatile. They are weather resistant (IP67) and the terminal screw style allow you to use them and reuse them for different applications. Add in the higher voltage rating -250V- allows them to be used on so many systems. (Note I would never use these at a voltage above 120V personally) So for years I used the brand name ones - work was paying - and I wanted that brand name to assure the ratings were legitimate IEC certs, etc. Note I had a number of issues with the brand name ones, the terminal set screws would often break when trying to tighten them down, the threads were course and would often not fully seat, and overall the cheap metal/plastic of the threaded connections were just not well made. So now retired I need a few replacements for around the home projects and did not want to pay for name brand units (heck these were minor house projects at low voltage). So I took a shot on buying these units. OMG these are so much better made than the brand name ones I have been using it is ridiculous. The threaded connectors are clean, heavy duty and thread fully together tightly assuring a great weather proof seal (the brand name ones almost never fully engaged properly). The screw terminals are at least twice as beefy and clearly better made. And the terminal labeling is clear and easy to read (some of the brand name ones you need a magnifying glass to even see them). Clearly these are much better made units. And a fraction of the cost. Note of caution though - I do not see in their listing any reference at all to any IEC or other certification. This is probably why they are so much lower cost - those certifications come at a cost. But for my application (no certification or liability involved) these are by far the best value - and will definitely be my go to for future projects. Thank you so much for making a product that far exceeded my expectations. Review: Well made - These are easy to use and solidly built. I used them for video in my van. They are larger than the typical aviation connector so you need to use them in pairs. ## Features - 【M12 Connector】M12 Field Wireable Connector,A Code,4Pin,Male+Female,Straight,For Cable,Screw-Joint,Unshield,IP67 Waterproof.Professional factory, support customization！Professional factory, support customization！ - 【High Quality 】M12 4-Pin Male+Female Circular Aviation Connector use professional high quality black rubber bakeute makes it Insulation and flame retardant.Thread locking mechanism,anti vibration locking design,12mm thread joint.Waterproof led connector use All-copper nickel-plated metal screw sleeve,pure copper gold-plated contacts,robust and corrosion-resistant,durable,while ensuring the stability and reliability of data and signals. - 【Easy to Use】12mm Aviation Wire Connector Plug:Easy quick connect and disconnect coupling;No tools required for installation and removal,M12 Cable Plug provide quick and easy connection between field devices and terminal connections,flexible and convenient plug-and-play.Suitable for DIY of single-ended aviation connector cables,allowing you to freely combine and match to complete the work efficiently and quickly.Even for non-technical personnel, can be easily installed and replaced. - 【Application】The 12mm Industrial Circular Connector widely used in signal electronic connector of aviation,computer, various kinds of instruments and industrial cameras,electric bicycles,factory automation,can be easily connected to proximity switches,photoelectric barriers, flow monitoring devices,sensor devices and ctuator devices and field bus components. - 【Package includes】4*Male+4*Female Waterproof 4 Pin Aviation Connector ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #366 in Audio & Video Connectors & Adapters | | Customer Reviews | 4.2 out of 5 stars 52 Reviews | ## Images ![M12 4 Pin Male & Female Socket Panel Aviation Wire Connector,12mm Industrial Circular Connector,Outdoor Waterproof IP67,4 Sets - Image 1](https://m.media-amazon.com/images/I/71nx4nNZz3L.jpg) ![M12 4 Pin Male & Female Socket Panel Aviation Wire Connector,12mm Industrial Circular Connector,Outdoor Waterproof IP67,4 Sets - Image 2](https://m.media-amazon.com/images/I/71O0W0Y-HyL.jpg) ![M12 4 Pin Male & Female Socket Panel Aviation Wire Connector,12mm Industrial Circular Connector,Outdoor Waterproof IP67,4 Sets - Image 3](https://m.media-amazon.com/images/I/71chiIY5adL.jpg) ![M12 4 Pin Male & Female Socket Panel Aviation Wire Connector,12mm Industrial Circular Connector,Outdoor Waterproof IP67,4 Sets - Image 4](https://m.media-amazon.com/images/I/71pNuf2eRrL.jpg) ![M12 4 Pin Male & Female Socket Panel Aviation Wire Connector,12mm Industrial Circular Connector,Outdoor Waterproof IP67,4 Sets - Image 5](https://m.media-amazon.com/images/I/71bQNCML6gL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Hello, do you have conector M12 4 pin Code D?** A: https://www.amazon.com/dp/B0C4NL4CF9?ref=myi_title_dp,Hello, this one is M12 connector 4 pin D code, and it is a newly upgraded all-alloy shell with better quality. **Q: What's the gauge size of the internal 4 wires ? Do you have one to support 24-28 AWG ?** A: Hello, I am sorry that there is currently no 24-28 AWG M12 connector on the market. The specification of the wire: the diameter of the wire cannot be greater than 8mm. **Q: What is the quality of the M12 connector,Can they be used in industry？** A: I started using these M12 4 Pin connectors in my home after retirement. But the quality of these is so much better than what I've been using in past work for the last 20 years from a well-known manufacturer, I can't even believe these are better quality for less. **Q: I need waterproof 4-pin connectors for plasma CNC control box (out to step motors). Using 22AWG shielded wire. Will these connectors be a good choice?** A: The shielding effect of this one may not be satisfactory to you. We recommend another M12 aviation connector for you: https://www.amazon.com/dp/B0C4NFPT3D?ref=myi_title_dp&th=1, it also has IP67 waterproof, And the shielding effect is better, and it is more resistant to corrosion and oxidation. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome product far better construction than the "Name Brand" units. *by E***H on December 22, 2022* I have been using a similar product from a well known manufacturer for more than 20 years and paying almost 5x the price for a lower quality product.

I used them for video in my van. They are larger than the typical aviation connector so you need to use them in pairs. ### ⭐⭐⭐ Not for frequent connect and disconnect *by J***T on May 13, 2026* Don’t use these if you intend to take them apart and put them together often. If you’re going to connect these and leave them permanently, then they should be fine. The pins are very weak and if you happen to insert the plugs in just the wrong way they bend. ## Frequently Bought Together - Lonlonty M12 4 Pin Male & Female Socket Panel Aviation Wire Connector,12mm Industrial Circular Connector,Outdoor Waterproof IP67,4 Sets - M12 4 Pin Male Aviation Panel Mount Connector,Lonlonty 12mm Waterproof Chassis Panel Back Mount Socket Sensor Connector 5PCS --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/478876026-m12-4-pin-male-and-female-socket-panel-aviation-wire](https://www.desertcart.hr/products/478876026-m12-4-pin-male-and-female-socket-panel-aviation-wire) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-04*
