Fixed cable glands force you to cut and re-terminate cables every time the panel changes. Modular cable entry doesn't. Here are five places that adds up to real hours.

The Quick Answer
Conta-Clip’s KDS-SR modular cable entry system carries the same IP66 protection rating as traditional cable glands but uses split inserts in a re-openable frame. That difference matters in five specific scenarios: late design changes, service retrofits, field modifications, pre-terminated cable installations, and panel variant builds. Each scenario eliminates a "cut and re-terminate" cycle that fixed glands force.
Cable glands have a reputation for being boring. They're a commodity. They seal a hole. They've been doing the same job the same way for decades.
The reputation is mostly fair — until the moment a panel changes. That's when the difference between fixed cable glands and modular cable entry shows up, and where the labor cost of fixed glands becomes visible.
KDS-SR is Conta-Clip's modular cable entry system. Same IP66 rating as traditional glands, same protection against dust and water, same compliance for harsh environments. The difference is what happens when you need to change something.
A traditional cable gland is a one-piece compression fitting. The cable passes through a sealing element, the gland is tightened, the seal forms. To change the cable, the gland comes off, the new cable goes in, the gland gets retightened. If the cable has a connector or other large termination, it usually has to be cut off first.
KDS-SR is a frame mounted into the panel cutout, with split inserts that snap closed around each cable. Each insert handles a specific cable diameter. Because the inserts are split, they open without disturbing the cable termination — cables with connectors already attached pass through, get cradled in the insert, and seal when the frame closes.
That construction difference unlocks five scenarios where rework time drops significantly.
The sensor gets swapped at the last minute. The new cable diameter doesn't match the existing gland. With a fixed gland, that means removing the gland, sourcing a new one in the right size, and (if the connector is already terminated) cutting the connector off, threading the cable through, and re-terminating.
With KDS-SR, the frame stays in place. You swap the affected insert for one in the new diameter, drop the cable through, close the insert. No re-termination, no waiting on a part, no cascading delay.
Time saved: Typically 30-60 minutes per affected cable, more if the connector type isn't held in stock for re-termination.
A panel comes back to the floor for an upgrade or repair. To pull a cable that needs replacement, traditional glands force the cable to be cut at the gland (since the connector won't pass through) and re-terminated after the new cable is run.
KDS-SR’s split inserts open in place. The old cable lifts out, the new cable drops in, the insert closes. The connector stays intact on both ends. For shops doing regular service work or building panels that will see retrofits in the field, this is the most consistent labor saving across the year.
A field tech needs to add a single I/O point on a deployed panel. With fixed glands, that often means a half-day job: pull the panel offline, find or drill a new gland location, source the right gland, run the cable, terminate it, restore power.
With KDS-SR, if the frame has spare insert slots (and they're typically spec'd with one or two), the tech opens an empty slot, runs the cable through with its connector intact, closes the insert. The job stays in the 20-30 minute range it should be.
This advantage compounds for OEMs whose panels live in the field for years and accumulate small modifications.
Many cable assemblies arrive pre-terminated — M12 cordsets, custom harnesses, factory-built sensor cables. With traditional glands, those terminations either have to come off and be re-attached after the cable passes through, or the gland has to be sized large enough for the connector to fit, often compromising the seal.
KDS-SR is built for pre-terminated cables. The split inserts close around the cable behind the connector, sealing without requiring the connector to pass through. For shops doing high volumes of M12 or custom-cordset installations, this eliminates an entire labor step per cable.
If you build the same base panel in multiple configurations — different I/O counts, optional sensor packages, regional variants — traditional glands force a different panel cutout pattern for each variant. That means more SKUs, more cutout templates, more chances for the wrong gland to land on the wrong panel.
KDS-SR uses a standard frame with interchangeable inserts. One frame size handles multiple variants by changing which inserts go in. Fewer SKUs to manage, simpler engineering documentation, easier last-minute variant swaps on the floor.
| Scenario | Traditional Cable Gland | KDS-SR Modular Entry |
|---|---|---|
| Cable diameter change | Replace entire gland | Swap insert only |
| Cable removal/replacement | Cut and re-terminate | Open insert, swap cable |
| Pre-terminated cables | Connector won’t fit through | Built for them |
| Adding a cable in the field | Drill new hole, add gland | Use spare insert slot |
| Multi-variant panels | Different cutouts per variant | One frame, swappable inserts |
| Protection rating | IP66 typical | IP66 |
KDS-SR isn't a universal replacement. Single-cable entries, deeply cost-sensitive panels with no expected modifications, and applications with extremely specialized environmental requirements (chemical immersion, explosive atmospheres requiring specific certifications) may still favor traditional glands or specialized fittings.
The case for KDS-SR is strongest when the panel will see multiple cable entries, any kind of change-frequency — design or field — and a workflow where pre-terminated cables are common.

Modular cable entry is a panel cable entry system that uses a fixed frame with split, interchangeable inserts instead of individual one-piece glands. Each insert seals around a specific cable diameter, and inserts can be opened, swapped, or replaced without removing the frame from the panel. KDS-SR is Conta-Clip’s implementation of modular cable entry.
KDS-SR carries an IP66 protection rating — the same rating as most industrial-grade traditional cable glands. IP66 protects against dust ingress and powerful water jets, which makes it suitable for indoor industrial environments and most outdoor applications.

Yes. The split-insert design closes around the cable behind the connector, allowing pre-terminated cables (M12 cordsets, custom harnesses, factory-built sensor cables) to pass through and seal without removing the termination. This is one of the primary use cases for modular cable entry over traditional glands.
On a per-cable upfront cost basis, modular cable entry is typically slightly more expensive than equivalent traditional glands. The total cost picture changes when you factor in labor savings on changes, retrofits, and field modifications — especially for panels that will see any modification activity over their service life. ElectroShield can quote both options on the same BOM for direct comparison.
Traditional glands are usually still the right call for single-cable entries, panels with no expected modifications over their service life, deeply cost-constrained projects, and specialized environmental applications requiring certifications beyond standard IP66 (such as ATEX or chemical-immersion ratings). For most industrial control panels with multiple cable entries, modular entry typically wins on total cost of ownership.
