TH405 Kabelkupplung männlich 3 polig

The TH405 series is Techno's large circular connector — 38 mm outside diameter, rated for 17.5 A at 400 V AC with an impulse withstand voltage of 6 kV. Both halves sit on the cable; the panel-mount version of the same connection is our TH406.

Piercing termination

With piercing termination the clamping screw pierces the core insulation — the conductor does not need stripping. In field assembly that removes the step most likely to go wrong and makes the joint independent of how cleanly someone stripped the wire.

Bayonet locking

Locking is by bayonet rather than a screw coupling — a quarter turn that audibly engages. That makes the series attractive where connections are broken and remade in the field and no tool is at hand.

Which half goes where?

This version combines the cable socket with pin contacts (Ø 38 × 80 mm) and the cable plug with socket contacts (Ø 38 × 75.7 mm). Mated, the connection measures Ø 38 × 141.2 mm. We offer the mirrored arrangement as the reversed-contact version.

Pole counts and contact marking

2, 3, 5 and 6-pole versions are available. The protective earth counts as a pole: 2-pole is L-N, 3-pole L-N-E, 5-pole 1-2-L-N-E and 6-pole 1-2-3-L-N-E. Cable diameter is 7 to 13.5 mm.

Protection and materials

Protection rating is IP66 and IP68. The plastic parts are black, the sealing elements Techno green, the contacts brass. For the North American market the rating is 20 A at 400 V AC/DC.

The same series is also available with screw and crimp termination. We assemble other configurations to order. Get in touch.
