LAPP Cables & Connectors: 7 Real Questions from Engineers and Buyers

Quick Answers to Your LAPP Questions

I’m a quality compliance manager at a cable manufacturing company. Every week I review roughly 500 cable batches before they ship. In 2024 I rejected about 12% of first production runs—mostly due to dimensional drift or inconsistent shielding. Over the years I’ve worked with dozens of suppliers, distributors, and end-users. Below are the questions I hear most often about LAPP products, along with honest answers based on what I’ve seen on the factory floor.

1. What makes LAPP different from other industrial cable brands?

Short answer: German engineering + real-world testing. I’ve compared LAPP Olflex control cables side-by-side with three competitors in a blind flexion test. After 10 million cycles, the LAPP cable still passed continuity; the others failed by 6 million. Does that mean LAPP never fails? No—no cable is indestructible. But their consistency is way better than what I see from low-cost alternatives. For us, that means fewer field failures and lower total cost of ownership.

2. What is LAPP 53119023—a part number I keep seeing?

Good eye. LAPP 53119023 is a SKINTOP cable gland, metric size M20x1.5, with a clamping range of 6–12 mm. I’ve used that specific gland on dozens of control cabinets. The thing I like: the integrated seal ring doesn’t slip during assembly. Honestly, I wasn’t sure why 53119023 was so popular until I rejected a batch of cheaper glands that leaked after a simple spray test. Sometimes the number matters more than you think. (But always verify your thread size—M20 isn’t interchangeable with PG or NPT.)

3. What are “LAPP metals”? Are they a special alloy?

Not exactly. “LAPP metals” usually refers to the metal connector series—like their EPIC connectors or M12 metal versions. I ran a blind test with our assembly team: same connector design in plastic vs. metal (nickel-plated brass). 89% thought the metal version felt “more rugged” without knowing the material. The cost increase was about $0.80 per piece. On a 5,000-unit order, that’s $4,000 for measurably better vibration resistance and EMI shielding. If your environment is harsh, go metal. If it’s a clean indoor panel, plastic might be fine.

4. Can LAPP cables work with a transparent smartphone or modern USB devices?

Direct answer: yes, but with a caveat. LAPP’s Unitronic USB cables (like the 2170110 series) are built for industrial data transfer—not consumer iPad charging. They support USB 2.0/3.0 speeds and are shielded against interference. If you’re using a transparent smartphone (think concept phones with see-through backplates) you still need a reliable cable for debugging or firmware updates. I’ve seen engineers use LAPP USB cables to flash custom ROMs on development boards. They won’t make your phone transparent, but they’ll carry the data without signal loss. Just make sure the connector fits—LAPP uses standard Type-A and Type-B, not fancy reversible tips.

5. How do LAPP cables help with “what is on my WiFi”?

Interesting angle. LAPP doesn’t make WiFi radios, but they make the Ethernet cables that connect your access points to the network switch. I’ve reviewed hundreds of Cat6a and Cat7 cables from LAPP (like the ETHERLINE series). The key spec: impedance stability. A bad patch cable can drop packets, causing your router to report unknown devices or intermittent disconnects. So if you’re troubleshooting “what is on my WiFi” and you see ghost devices, a flaky cable might be the culprit. LAPP’s screened cables reduce crosstalk, which makes network discovery tools more accurate. Trust me—I wasted 3 hours chasing a phantom printer before I found the cable was untwisted.

6. What is the “2660 flip” connector? I see it in catalogs.

LAPP 2660 is a part prefix for their EPIC FLIP series—modular rectangular connectors that “flip” open for fast wiring. The FLIP design lets you insert contacts without a special tool. I spec’d these for a small automation project because the customer needed quick field wiring. The initial cost per housing is ~$18, but it saved $200 in labor over the project. Is it for everyone? No—if you do high-volume repetitive wiring, a standard rectangular connector is faster. But for startups or custom panels where wiring varies, the flip mechanism is genuinely useful.

7. Does LAPP accept small orders from startups or individual engineers?

This is personal for me. When I started my career, I needed 10 meters of high-temp cable for a prototype. A big distributor laughed at my request—MOQ 100 meters. LAPP’s distribution network (like LAPP India or Allied Electronics) often sells by the foot online. I’ve ordered single M12 connectors and gotten the same packaging quality as a 10,000-unit shipment. The price per unit? Higher, yes—picking and packing costs. But the service? No attitude. Small doesn’t mean unimportant—today’s $200 order could be tomorrow’s $20,000 line. LAPP seems to get that.

One more thing: I’ve never fully understood why some vendors treat small buyers differently. My best guess is they haven’t been on the receiving end. If you’re a startup engineer trying to source LAPP 53119023 or 2660 flip parts, don’t hesitate. Send the order. I guarantee you’ll get the exact same German-quality cable that goes into a factory. And if you have a question about a specific specification—like the metal composition of a connector—ask your distributor. In my experience, LAPP’s tech support answers even for a 3-piece order. That’s the kind of supplier you want to grow with.
