Screw-Terminal Inline Connectors
Inline plug-and-socket and splice connectors with screw terminals for joining two cables.
- Connection: Fixed splice or detachable plug-and-socket form
- Terminals: Pole count and conductor cross-section
- Cable seals: Outside diameter of both cables
Waterproof connector groups
Inline joints and branched cable connections.
Inline connectors join two cables. T, Y and multi-way connectors route branches, with screw, push-in or lever terminals across the range.

Screw-Terminal Inline Connectors FAQ
Product questions
Find answers about fit, wiring and product differences.
Screw-Terminal Inline Connectors
01Are all inline connectors detachable?
No. A splice connects conductors inside one body. A plug-and-socket design separates at a mating interface. Choose according to how the equipment will be serviced.
02Can the two cable ends have different diameters?
Only if each cable fits the seal range on its side. Check the two entry ranges separately, along with the terminal capacity for each conductor.
ZXM16 / ZXM20 Screw-Terminal In-Line Connectors
ZXM16 / ZXM20 Screw-Terminal In-Line Connectors
01How do ZXM16 and ZXM20 differ?
ZXM16 accepts 0.2–2.5 mm² conductors and has 2 or 3 contacts. ZXM20 accepts 0.5–4 mm² conductors and has 2, 3 or 4 contacts.
02Which cable diameters fit ZXM16 and ZXM20?
ZXM16 seal options cover 3–6.5, 5–8 or 7–10 mm cable outside diameter. ZXM20 seal options cover 5–8 or 9–12 mm.
03What tightening torque do ZXM16 and ZXM20 use?
The installation torque is 0.6–0.8 N·m for both sizes.
04How do I select a ZXM16 or ZXM20 order code?
Match the connector size, contact count and cable outside diameter to one row in the model table. Conductor cross-section and cable-jacket diameter are separate measurements.
ZXM25 Screw-Terminal In-Line Connector
ZXM25 Screw-Terminal In-Line Connector
01What distinguishes ZXM25 from the KCM25 lever connector?
ZXM25 uses screws and has a 0.5–6 mm² conductor range. KCM25 uses levers and has a 0.5–2.5 mm² range. Their terminals are different despite the similar cable-seal options.
02Which cable diameters fit this ZXM25?
The seal options cover 5–8, 9–12 or 10–14 mm. These are cable-jacket diameters, separate from the conductor cross-section.
ZXM25 Multi-Hole Cable Connector
ZXM25 Multi-Hole Cable Connector
01Is this ZXM25 product only a cable gland?
No. It includes an electrical screw-terminal connection as well as the cable-entry seal. A cable gland on its own does not join conductors.
02Can several small cables share one oversized sealing hole?
Each cable needs its own correctly sized sealing hole. A custom multi-hole insert is used to match the individual cable diameters.
