CNLINKO 4-Pin IP67 Female Plug vs Arlington 38AST Snap2 50-Pack: Which Connector Fits Your Job?

For control cable, connector, and I/O work, the CNLINKO 4-pin female plug offers IP67 protection at $13.62, while the Arlington 38AST Snap2 lot supplies tool-free MC/AC cable terminations at $52.26.

Last updated Aug 17, 2026

Choosing between the CNLINKO 4-pin connector and the Arlington 38AST Snap2 IT connector comes down to one question: are you making a water/dust-resistant power or signal connection, or are you terminating metal-clad cable at an electrical box? In the control cables, connectors, and I/O world, these two products take very different jobs. The CNLINKO is a single female plug with water/dust protection. The Arlington is a bulk conduit connector option for MC/AC cable runs.

Quick Verdict

Pick the CNLINKO female plug when you need one waterproof 4-pin connection. Pick the Arlington lot when you need a supply of tool-free snap-in connectors for metal-clad cable.

Where Each Product Wins

CNLINKO wins when you need a single, sealed, quick-disconnect connection. Its quick-disconnect design and dustproof cover make it practical where the connector will be coupled and uncoupled repeatedly.

Arlington wins when speed and quantity matter. The Snap2 IT design is made for speed: you snap the cable into the fitting and then snap it into the box. With a full lot in hand, it suits jobs with many boxes or many cable runs.

Product Notes

CNLINKO 4-Pin Power Industrial Connector Female Plug

CNLINKO 4 Pin Power Industrial Connector Female Plug Waterproof IP67 Signal M20

Choose this CNLINKO female plug when the connection needs to handle both power and environmental exposure. It carries a 20A rms current rating, accepts 14-12 AWG cable, and uses gold-plated contacts for corrosion resistance and conductivity. The quarter-turn bayonet coupling makes attachment and release quick, and the dustproof cover protects the connector while it is uncoupled. The connector carries UL, CE, and RoHS certifications, so it is suited to industrial use. One limitation: this is the female plug only, and the matching socket is the YM-20-C04SX-02-401, so you need the mating piece to complete a full connection.

Arlington Industries 38AST 3/8-inch Snap2 IT Connector Lot of 50

Arlington Industries 38AST 3/8" Snap2 IT Connector Lot of 50

If your project means terminating MC/HCF or AC/HCF cable at multiple boxes, this 50-piece lot of Arlington 38AST connectors is a practical bulk supply. The zinc die-cast body is built for snap-in installation: you push the cable into the fitting, snap it into the box, and loosen the top screw to release it. The accepted cable range is .405 to .612, which suits the 3/8-inch Snap2 IT conduit/cable size. At $52.26 for 50 connectors, the lot covers repeated terminations in one purchase. The trade-off is that this is not a sealed multi-pin plug; it is a cable-to-box connector for MC/AC installations.

Final Choice by Use Case

Use the CNLINKO female plug when you need a single, sealed, quick-coupling 4-pin connection. Use the Arlington lot when you are terminating metal-clad cable at multiple boxes and want a bulk supply of snap-in connectors on hand.
