Choosing between two rugged CNLINKO IP67 connectors starts with a simple question: does your control cable need data or power? The Circular Ethernet Industrial Connector is a male RJ45 plug built for outdoor Ethernet runs and straightforward use. The 4 Pin Power Industrial Connector is a female M20 plug for power-focused control runs. Both are new, CNLINKO-branded, and carry UL, CE, and RoHS certifications, so the real difference is how you wire the system, not whether they can handle weather.
Quick Verdict
- For an RJ45 data run: go with the CNLINKO Ethernet RJ45 plug.
- For heavier wiring jobs: go with the CNLINKO power plug.
Comparison
| Product | Price | Price level | Connecting mode | Best for |
|---|---|---|---|---|
| CNLINKO Circular Ethernet RJ45 Male Plug | $9.49 | Plug/Unplug | Outdoor Ethernet runs | |
| CNLINKO 4 Pin Power Female Plug M20 | $13.62 | 1/4 Quick bayonet | Power-centric runs with 14-12 AWG |
Where Each Product Wins
RJ45 plug. The RJ45 plug is convenient for frequent disconnects, and the operating range of -40°C to 80°C suits exposed industrial locations. The body uses ABS and zinc rather than ABS on its own, giving it a different material profile from the power plug. For a pure RJ45 data connection, it is the direct fit.
Power plug. This connector carries a 20A rms current rating, and the gold-plated contacts are designed for corrosion resistance and stable conductivity. That makes it the stronger candidate once power is part of the cable run.
Product Notes
#### CNLINKO Circular Ethernet RJ45 Male Plug
The RJ45 male plug is the data-side option in this pair. Its body combines ABS and zinc, while the power plug uses ABS, so the material mix is different if that matters in your setup. You connect it with a simple plug/unplug action, which is convenient when cables are swapped often. The operating range of -40°C to 80°C makes it usable in cold outdoor cabinets. A concrete reason to choose it: if your control run is Ethernet/RJ45, this is the matching connector, and it is the lower-priced of the two at $9.49. The limitation to plan around is gender and type: it is a male RJ45 plug, so you need a female RJ45 port or jack rather than a bayonet power socket.
#### CNLINKO 4 Pin Power Female Plug M20
This M20 female plug brings four pins into one connector, so signal and power can share the same coupling. It accepts 14-12 AWG wire, supports AC/DC, and is rated for 20A rms. The 1/4 quick bayonet coupling locks the plug in place with a quarter turn, which is a different connection action from the RJ45 plug's push-pull motion. Gold-plated contacts also give the connector a corrosion-resistant contact surface. A concrete reason to choose it: the 20A rating makes it the one for power-carrying control cables in 14-12 AWG. The limitation to plan around is that this is a female bayonet connector in an M20 form, so it needs a matching male bayonet connector rather than an RJ45 jack.
Final Choice by Use Case
Use the CNLINKO Ethernet RJ45 plug for data runs.
Use the CNLINKO power plug for control cables that carry power and signal together.
The deciding point is the cable itself: an RJ45 data cable points to the Ethernet plug, while a multi-wire power/signal cable points to the power plug.
