When you are outfitting control cables, connectors, and I/O hardware, two very different automation parts can end up on the same shopping list. One is a Keyence control cable; the other is a Moxa I/O part for networked installations. They are not interchangeable, but they can compete for the same budget when a single purchase is on the table. The useful way to decide is to name the exact job: do you need a wire to carry a control signal, or do you need a network-connected I/O point?
Quick verdict
If the missing piece is a Keyence control cable and the part number has to match, buy the OP-87529. If the missing piece is an Ethernet remote I/O endpoint, choose the Moxa ioLogik E1242-T-it is the only part here that serves that role.
Listed-price comparison
| Product | Listed Price | Price Bar | Condition | What it does |
|---|---|---|---|---|
| Keyence OP-87529 Industrial Control Cable | $190.00 | New | Industrial control cable | |
| Moxa ioLogik E1242-T Ethernet Remote I/O Module | $110.00 | New - Open box | Ethernet remote I/O module, 12-36VDC |
Where each product wins
Where the Keyence cable wins
The OP-87529 wins when your part number has to be exact. The title names the brand, model, and cable type, so there is no guesswork about what you are ordering. It carries the higher listed price in this comparison, which is easier to accept when fit accuracy is the priority.
Where the Moxa module wins
The ioLogik E1242-T wins when the job is about adding I/O points across a network. It carries the lower listed price in this pairing and is the only part here that can serve as a network I/O endpoint.
Product notes
Keyence OP-87529 Industrial Control Cable
For a user hunting for a specific replacement cable, the OP-87529 has the advantage of being an explicit match: the title names the brand, model, and part type. The part is identified as made in Japan, which is helpful if you are keeping a Japanese-built control system consistent. The limitation is that it is only a cable. It sits at the top of the $110-to-$190 spread for this comparison, and it does not add remote I/O capacity. If your real need is expanding inputs and outputs over Ethernet, this cable alone will not give you an endpoint. Buy it when the job is literal: connect one control signal between devices using the exact Keyence part.
Moxa ioLogik E1242-T Ethernet Remote I/O Module
Keep the Moxa module in mind when the project already has a controller and the missing piece is remote I/O. Its title identifies it as an Ethernet remote I/O module powered by 12-36VDC, so it fits into a networked control setup rather than a point-to-point wiring job. It also sits at the lower end of the two-part price range. The limitation is its open-box condition: the unit is New - Open box, meaning the original box is gone even though the module is described as new and undamaged. That should not stop you if you are installing the part into a panel, but it does mean the packaging is not part of the deal. Choose it when the job calls for an I/O endpoint, not a cable.
Final choice by use case
- Pick the Keyence OP-87529 for a direct control-cable replacement. The title is explicit about brand, model, and part type, so it suits an application where the machine already expects that Keyence cable.
- Pick the Moxa ioLogik E1242-T for remote I/O expansion. It fits an installation that needs to add or replace I/O points rather than rewire a single signal.
- If you are only doing point-to-point wiring, the Moxa module will not help; if you are only adding network I/O, the Keyence cable will not help.
