Brass Flat Cable Gland
The Brass Flat Cable Gland is engineered for industrial applications requiring secure routing and sealing of flat cables (ribbon cables) into control panels, machinery, and electrical enclosures. Unlike round cable glands that distort rectangular profiles, this design utilizes a slotted internal seal and an integrated clamping insert. This configuration distributes uniform mechanical pressure across the flat cable perimeter, ensuring a reliable strain relief and a strict IP68 ingress seal without conductor crushing.

Key Features
Metallurgical Integrity: Precision-machined from solid brass bar stock (CuZn39Pb3 / CW614N / H58) with optional electroplated nickel finish to resist chemical exposure and saline corrosion in harsh industrial settings.
Specialized Flat Sealing Geometry: Custom-molded TPE/EPDM elastomeric inserts match distinct rectangular cross-sections, closing gaps that cause leaks in standard round conduit fittings.
Mechanical Strain Relief: Engineered claw design locks the outer jacket firmly, preventing axial pull-out forces from transmitting to internal terminal blocks.
Environmental Sealing: Maintains continuous IP68 (up to 5 bar) and IP69K protection when paired with matched thread sealing rings.

Quality Control & Manufacturing Evidence
Raw Material Testing: Spectrometer material verification ensures incoming brass stock matches chemical composition limits per EN 12164.
Dimensional & Thread QA: 100% automated optical sorting combined with Go/No-Go thread gauge testing to ensure ISO 965-1 class 6g tolerances.
Sealing Performance Audits: Regular burst-pressure and hydrostatic immersion sample testing to verify IP68 performance thresholds.
Traceability: Laser-engraved production batch codes link finished components directly to mill test certificates (MTC available per EN 10204 3.1).
Frequently Asked Questions
Q: How do I calculate the correct gland size for a non-standard flat cable?
A: Measure the maximum width and thickness of your flat cable. Select a gland model whose internal sealing aperture range encompasses both dimensions to ensure perimeter compression without pinching the inner conductors.
Q: Will these glands withstand high-vibration industrial environments?
A: Yes. The internal clamping claw anchors the cable jacket mechanically, resisting loosening caused by continuous machinery vibration or mechanical shock.
Q: What thread tolerance standard is applied during manufacturing?
A: Metric threads are machined strictly to ISO 965-1 class 6g specifications, ensuring smooth and reliable engagement with tapped holes or matching locknuts.
Q: Are low-smoke, halogen-free (LSZH) seal inserts available?
A: Yes. EPDM and silicone elastomer inserts meeting specific fire safety and low-smoke emission standards can be supplied for transit and rail applications.
Q: What is the minimum order quantity (MOQ) for custom thread lengths or apertures?
A: Standard catalog items are available in flexible batch sizes. Custom non-standard machining requires an engineering review to determine economic production batch minimums.
Q: What quality documentation accompanies shipments?
A: Shipments include a Certificate of Conformity (CoC) as standard. Material Test Certificates (MTC 3.1) can be provided upon request prior to dispatch.
