T-Branch Waterproof Connectors FAQ
Product questions
Find answers about fit, wiring and product differences.
T-Branch Waterproof Connectors
01Does a T shape tell me which conductors connect?
No. The shape shows the cable routes. Check the terminal layout to see how each conductor connects between the three entries.
02Do all three ports accept the same cable size?
Do not assume so. Compare the cable sealing range for each port with the diameter of the cable that will enter it.
TXM20 Press-Terminal T-Connector
TXM20 Press-Terminal T-Connector
01Which TXM20 models use the press-type terminal?
The press-terminal range uses TXM20-06 through TXM20-09. The screw-terminal range has separate model numbers, TXM20-10 through TXM20-13.
02Which cable diameters fit this TXM20?
The seal options cover 5–8 or 9–12 mm. These are cable-jacket diameters, separate from the conductor cross-section.
TXM20 Screw-Terminal T-Connector
TXM20 Screw-Terminal T-Connector
01Which screw-terminal TXM20 fits a 3-contact, 9–12 mm cable connection?
TXM20-13 provides 3 contacts with the 9–12 mm cable seal. TXM20-12 uses the same contact count with a 5–8 mm seal.
02Which cable diameters fit this TXM20?
The seal options cover 5–8 or 9–12 mm. These are cable-jacket diameters, separate from the conductor cross-section.
TXM25 Screw-Terminal T-Connector
TXM25 Screw-Terminal T-Connector
01How does TXM25 differ from the screw-terminal TXM20?
TXM25 has a 0.5–2.5 mm² conductor range and includes a 10–14 mm cable-seal option. The screw-terminal TXM20 accepts 0.5–4 mm² conductors with 5–8 or 9–12 mm cable seals.
02Which cable diameters fit this TXM25?
The seal options cover 5–8, 9–12 or 10–14 mm. These are cable-jacket diameters, separate from the conductor cross-section.
03Can I order TXM25 by the model code alone?
No. Some TXM25 codes occur with more than one contact count or cable seal. Include the contact count and cable outside diameter with the code so the required configuration is unambiguous.
