Choosing between a ready-made control cable and a field-wireable connector can feel odd until you realize they solve different problems. The Keyence OP-87529 is a ready-made industrial control cable; the CNLINKO 4 Pin Power Industrial Connector is a female plug you wire yourself, intended for signal and power connections. One is a defined replacement part; the other is a building block for your own wiring. The right pick depends on whether you are swapping a known part or building a connection from parts.
Quick Verdict
If you need a ready-made Keyence cable, the OP-87529 is the direct pick. If you prefer to wire your own connection, the CNLINKO female plug is the more flexible route.

Where Each Product Wins
Keyence OP-87529 wins when you want a complete cable rather than a connector to assemble. A new Keyence part with model OP-87529 fits a parts list for a machine that already uses Keyence components. You are not choosing contacts, pin layout, or wire range; you are choosing a specific cable.
CNLINKO wins when you are building a connection yourself. The female plug adds gold-plated contacts and an AC/DC current type to your wiring bill of materials, leaving the job of cutting cable and choosing the right mating socket up to you.
Product Notes
Keyence OP-87529
If your control panel already uses Keyence hardware, the OP-87529 Industrial Control Cable is a very direct option. It carries the Keyence brand and model OP-87529, and Controller Platform: Automate makes its intended home clear. That level of specificity is exactly what you want when you are replacing a known cable on a machine: one part, one part number. The limitation is that this is not a general-purpose wiring component. Because it is defined around a single Keyence model, it is not the part to buy if you are still designing the wiring layout or sourcing connectors across multiple vendors. It solves a specific Keyence part-number problem better than it solves an open-ended connector-build problem.
CNLINKO 4 Pin Power Industrial Connector Female Plug
CNLINKO's female plug is the opposite kind of purchase: you get the connector, and you supply the wire and the rest of the connection. The part combines a 1/4 quick bayonet coupling, gold-plated contacts, a 20A rms rating, IP67 waterproof protection, and support for 14-12 AWG wire, which is a strong combination for signal and power lines in industrial enclosures. It also lists UL, CE, and RoHS certificates, so the part carries documented approvals. The practical limitation is scope: this connector covers the female plug only, and the matching socket is called out as a separate model number (YM-20-C04SX-02-401). You also need to confirm that the M20 thread and 4-pin count fit your cable and enclosure before buying.
Final Choice by Use Case
Choose the Keyence OP-87529 when you need a specific Keyence control cable and you want the part to arrive with the model number on it. Choose the CNLINKO 4-pin female plug when you are building a connection and need a connector you can wire yourself. If you are maintaining existing Keyence equipment, the cable is the safer call. If you are wiring a panel or machine connection, the connector gives you the most control over the finished assembly.
