When you're wiring control panels and I/O points, the cable often becomes an afterthought - until you need to pull long runs or make a tight repair. The decision comes down to scale and fit: do you need bulk cable for a new installation, a ready-made assembly for an existing machine, or one brief section to reconnect a sensor? The four options below cover that range, and their listed prices lay out the trade-off from $10.99 to $641.24.
Quick take: The Belden roll is the heavy-duty choice for continuous runs. The LAPP OLFLEX cable handles quick repairs at a low price. The Keyence OP-87529 suits Keyence-based automation, and the Klockner Bartelt 500081 6 is the ready-made cable assembly.
Listed-price comparison:
| Product | Listed Price | Price Bar | Format |
|---|---|---|---|
| LAPP OLFLEX H05VVC4V5-K 14AWG 600V 8 Ft | USD 10.99 | Used, 8-ft cable | |
| Klockner Bartelt 500081 6 Control Cable Assembly | USD 159.99 | Used cable assembly | |
| Keyence OP-87529 Industrial Control Cable | USD 190.00 | New, single cable | |
| Belden 2AS-1801POS-B-B/R Control Cable, 482 Ft Roll | USD 641.24 | New open-box, 482-ft roll |
How to decide: If you're starting a new panel or pulling cable across a machine, buy by the roll. If you're fixing one point, a single cable makes more sense. If you need a drop-in assembly, look for a pre-built part that matches your control equipment.
Decision matrix:
- New panel or long conduit run: Belden roll.
- One-for-one replacement in a Keyence-based system: Keyence OP-87529.
- Drop-in cable assembly for control equipment: Klockner Bartelt 500081 6.
- Quick repair or test connection: LAPP OLFLEX cable.
Klockner Bartelt 500081 6 Industrial Control Cable Assembly
If your project calls for a pre-built control cable rather than bulk wire, the Klockner Bartelt 500081 6 is the one to look at. It's described as a used cable assembly with part number 500081-6, so you're getting a defined part instead of cutting your own lengths from a spool. At $159.99, it sits between the low-cost LAPP cable and the large Belden roll. The practical trade-off is the used condition and the fact that it's an assembly, so it's not meant for pulling long custom runs. As a drop-in control cable assembly, it gives you a ready-made option.
Belden 2AS-1801POS-B-B/R Industrial Control Cable, 482 Ft Roll
The Belden cable is the heavy-duty bulk option in this group. It's a 482-ft roll of 18 AWG control cable rated 600V TC 150V NPLF 90C dry/wet, and it's described as new open-box. At $641.24, it's the most expensive item here, but it's also the only one that gives you enough cable to wire multiple control points from a single roll. The 18 AWG and 600V ratings point to industrial control use, and the dry/wet rating adds flexibility for different installation environments. The limitation is the price and the open-box condition - you're making a larger investment for a longer project, not picking up a quick repair cable.
Keyence OP-87529 Industrial Control Cable
The Keyence OP-87529 is the option to consider when you're working with Keyence automation equipment. It's described as new, made in Japan, with a controller platform of Automate, so it's tied to a specific part number rather than being generic bulk cable. At $190.00, it costs more than the LAPP cable and slightly more than the Klockner Bartelt assembly, but you're paying for a single dedicated cable rather than a roll. The main limitation is exactly that: it's a one-piece part, not a continuous spool, so it suits replacement or point-to-point wiring instead of long-run installation. If your control system uses Keyence components, this OP-87529 is the one that fits that environment.
LAPP OLFLEX Industrial Control Cable H05VVC4V5-K 14AWG 600V 8 Ft
At $10.99, this LAPP OLFLEX cable is the entry point for anyone who just needs a quick run. It gives you 8 ft of 14 AWG cable with a 600V rating, and it's small enough to keep on hand for quick repairs or test connections. The used condition explains the price, and the brief length means you're not going to wire a whole cabinet from it. But if your task is a simple sensor hookup, a small panel jump, or a diagnostic cable, the low cost makes it practical. It's the least expensive option here, which makes sense for these point-of-use jobs.
Final recommendation: For continuous-installation runs, buy the Belden roll. For a point repair, the LAPP OLFLEX is the practical pick. For a Keyence-specific replacement, choose the Keyence OP-87529. For a pre-built control cable assembly, the Klockner Bartelt 500081 6 is the ready-made option. Start by measuring the actual distance and the number of I/O points you need to connect - that will tell you whether you're buying a roll, an assembly, or one cable.
