8.2 kΩ safety contact strip: select smart, connect cleanly
Is your gate's closing edge acting up? With the right contact strip, K-rail, end cap and matching spiral cable, your gate will run reliably – without any guesswork.
Why this topic is worthwhile
The 8.2 kΩ safety contact strip stops or reverses your gate upon contact – mandatory for many systems and simply sensible. However, problems often arise from details: incorrect profile height, unsuitable K-rail , missing end cap , or the wrong coiled cable . Here, we show you briefly and concisely how to correctly combine, install, and test the parts – with direct product links that are truly relevant.

✅ Advantages & Benefits
The closing edge detects contact immediately – the gate stops reliably.
The contact strip, K-rail, end cap and cable can be combined modularly.
Pre-assembled sets and clear connection diagrams save time and hassle.
⚙️ Technical Background
The control unit monitors a defined resistance. When the bar is pressed, the signal changes – the system stops or reverses.
Rubber profile (contact strip), K-rail as support, end cap with termination/conductor, spiral cable & junction box for control.
For high-power drives (e.g., 230/400 V), standard-compliant protection is mandatory. Observe the manufacturer's instructions.
🧭 Selection & Configuration
- Profile height : 65 mm is standard – check the installation situation.
- Support : K-rail of suitable length (usually 1 m segments).
- Termination : Select end cap with 8.2 kΩ & cable.
- Cabling : Spiral cable/junction box suitable for the controller.

🔧 Application & Connection
- Position the K-rail without tension, clip the profile in flush.
- Polarize the end cap with 8.2 kΩ correctly and guide it without kinks.
- Connect the spiral cable to the gate leaf socket and check the strain relief.
- Test “Pressure on bar” → Stop/Reverse must occur immediately.
- Combine with a light barrier/light grid – for added safety.
- Note down error codes and file the documentation.
Only work on electrical controls if you are experienced in this area. Otherwise: just ask us – we'll tell you what's suitable.
💡 Practice, Acknowledgements & News
Industrial sectional door kept running → the cause was a pinched cable at the end cap. Rerouted and replaced the spiral cable → clean stop.
Thanks for your photos of the gate leaf and the K-rail. This allows us to match the SKL, end cap and cable in minutes – avoiding incorrect purchases.

🧰 Maintenance & Care
- Monthly visual inspection: profile, cable, strain relief.
- Document annual functional tests (stop/reverse).
- In case of damage: Replace profile/end cap immediately.

❓ FAQ
What profile height do I need?
65 mm is suitable for many applications. The crucial factor is the installation space at the closing edge – photos can help with the selection.
Do I also need a light barrier?
Yes, often useful – it protects the driving path. The SKL (safety edge guard) protects the edge, the light barrier/light grid the area in front of it.
How can I tell if an end cap is defective?
Faulty stopping mechanism, loose connection, or visible cable damage. Check, replace – done.
Can I assemble the parts myself?
Yes, with care. Only make electrical connections if you are sure – otherwise, please contact us with a quick question.
Finish closing edge – drive safely
Strip, K-rail, end cap and coiled cable: once you've chosen the right ones, it works. If you want, we can check your set with a photo in a few minutes.
