Deciding between two industrial waterproof connectors comes down to one question: what are you actually connecting? In the control cables, connectors, and I/O space, both of these look like rugged round plugs, but they belong to different electrical families. The CNLINKO is the data-side plug. The CHALITECK is the power-side plug. The price difference is substantial: $9.49 for the CNLINKO and $69.00 for the CHALITECK.
Quick verdict If your connection is a data cable - an outdoor IP camera, an industrial network drop, or a remote device - the CNLINKO male plug is the practical pick. If your connection is power - a machine or a heavy electrical circuit - the CHALITECK plug is the one that can handle it.
At a glance
| Connector | Use case | Key details | Price bar | Price |
|---|---|---|---|---|
| CNLINKO RJ45 Industrial Connector | Outdoor data | IP67, RJ45 male plug | USD 9.49 | |
| CHALITECK 4-Pin Power Connector | Power circuits | IP67, 63A, pin-style pair | USD 69.00 |
Where the CNLINKO wins
- It is the only data connector here, built for RJ45 data runs.
- The ABS and zinc body suits a rugged outdoor connector.
- It carries UL, CE, and RoHS certifications and operates from -40°C to 80°C.
- The lower price makes it the sensible choice for a single sealed data port.
Where the CHALITECK wins
- It carries 63A of current capacity, which puts it in a different class from the CNLINKO.
- It comes as a male and female pair, so both ends of a power run are covered.
- Its pin-style design is built for heavy industrial power.
- The higher price buys power capability and a matched set.
Product notes
CNLINKO RJ45 Industrial Connector

The CNLINKO comes into its own when the signal travels over twisted-pair wiring. It is a male plug built for outdoor data runs, with a body formed from ABS and zinc and a plug/unplug connecting mode that makes it easy to seat or release the connection. The wide operating range of -40°C to 80°C fits cold storage areas, rooftop cabinets, and factory floors, and the UL, CE, and RoHS certifications give it clear credentials. The concrete reason to choose it is its role as a sealed data-side connector. Its limitation is that it stops at the network port: it is not a power connector for the heavy circuits the CHALITECK is designed to serve.
CHALITECK 4-Pin Power Connector

The CHALITECK is the connector you choose when the current has to do work. It is designed for IEC60309 applications and uses a 4-pin pin-style layout, so it belongs on power cables rather than network cables. It arrives as a matching pair, which removes the guesswork of finding a compatible mating half. The concrete reason to choose it is that you get both sides of a high-current connection in one order, built around the 3-phase standard. Its limitation is the flip side of that focus: it is not an RJ45 connector, so it cannot terminate network cable or carry network signals. Leave it in the power path and it will do what it was made to do.
Final choice by use case Choose the CNLINKO when you need an outdoor data connection without paying for power features. Choose the CHALITECK when you need a high-current 3-phase connection and a complete male/female set. The two are not interchangeable, so match the plug to the cable type and the circuit ahead of you.
