Description
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.
Reversed contacts
This version is the mirror image: the pin contacts sit in the cable socket (Ø 38 × 75.7 mm), the female contacts in the cable plug (Ø 38 × 80 mm). Which side stays live in operation decides the choice — the touchable pins belong on the side that is dead once disconnected. Techno offers the other arrangement as the standard version.
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.
Pole counts and contact marking
2, 3, 5, 6 and 8-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, 6-pole 1-2-3-L-N-E and 8-pole 1-2-3-4-5-6-7-E.
Termination
Conductors clamp with M3 screws at 0.8 Nm; cross-section runs from 0.5 to 1.5 mm², with up to 4 mm² permissible within the stated electrical ratings. Cable diameter is 7 to 13.5 mm and the gland nut is tightened to 2.5 Nm.
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 as a piercing version and in the Industrial variant for cables up to 16.5 mm. We assemble other configurations to order. Get in touch.
