What panel thickness can be used?

Up to 7 mm. The mounting nut is included. The cut-out follows the M16 thread.

How do M16, M20 and M25 differ?

Only in panel size. Electrically all three are identical: 25 A at 630 V AC, 0.5 to 2.5 mm², IP66 and IP68. M16 needs the smallest cut-out.

Which counterpart fits the panel connector?

Within the TH389U series, the panel plug connector mates with the cable socket connector and the panel socket connector with the cable plug connector, in each case with the same pole count. Whether a combination with another Techno series is possible is something we are happy to clarify case by case.

Description

The panel-mounted versions of the TH389U series with M16 gland sit in the enclosure wall and accept the matching cable connector from outside. They are rated for 25 A at 630 V AC, with conductor cross-sections from 0.5 to 2.5 mm² — stranded or solid.

Versions

Available as panel plug connector and panel socket connector, each with 2+PE and 3+PE poles. Supplied with a mounting nut; maximum panel thickness is 7 mm. Connection is by screw terminal at 0.8 Nm; strip 6 mm of conductor and 25 mm of sheath.

M16 is the smallest of the three panel sizes. Where more room is available, or where a larger cut-out already exists, the M20 and M25 versions are worth considering — electrically all three are identical.

Protection and materials

Protection rating is IP66 and IP68, impact resistance IK08. The housing is glass-fibre reinforced PA66 to UL94 V0, the gland PA66 to UL94 V2, the contacts brass. The temperature range runs from −40 to +125 °C with a maximum operating temperature of +70 °C. Tested to EN 61535, with CE and UKCA marking. The seals are silicone.
