Choosing cable glands: M12–M63 and cable diameter

An IP67 enclosure with the wrong gland has no protection at all. Selection by IEC 60423 thread and cable diameter, with our full M12–M63 table and the blanking plugs for unused entries.

The cable gland is the gateway where the cable enters the enclosure: too large and it leaks, too small and it cannot grip, the wrong thread and it will not screw in. However high the IP rating, one wrong gland reduces it to nothing.

Select by cable diameter (our full M12–M63 range)

These are WISKA ESKV polyamide glands — weather resistant, suited to feeding industrial socket enclosures.

Unused entries must be closed too

Openings in combinations and enclosures that are not used must be closed with blanking plugs, or water gets in anyway:

M3213–21 mm990625 (IP67)
M4016–28 mm990627 (IP67)

Two easily overlooked points

  1. The thread standard must match: glands use metric thread to IEC 60423, and the M size must match the enclosure opening.
  2. Clamping ranges differ between manufacturers: the same M20 may take a different cable diameter range — select on the manufacturer's stated clamping range, do not guess from the thread size.

How to choose industrial plugs and sockets: 5 steps to the right model
Current, poles, IP rating, mounting and brand — follow these five steps and you pick the right industrial plug or socket the first time, without trial and error.
IP44 vs IP67: what the two numbers really mean
The difference is not just a bit more water resistance. What IEC 60529 actually specifies, and how to choose for outdoor and wet areas.
Reading MENNEKES model numbers: 32xx / 27xxx / 13xA
How MENNEKES numbers its industrial plugs, sockets and connectors, and how to recognise a model at a glance.
Reading the MENNEKES 93xx series: 9322 / 9342 / 9372 / 9382 compared
93xx is the MENNEKES wall-mounted IP67 industrial socket series. The last digit gives the voltage, the third digit the poles and current. The full 9300–9382 table and the four comparisons people ask about most.
Can MENNEKES sockets be interchanged with other CEE brands? Check the clock position first
Interchangeability is not about the brand but four things: current, poles, clock position and IP rating. With the clock positions we verified against our own stock (110V = 4h, 230V single-phase = 6h, 400V 3-pole = 9h, 400V 4/5-pole = 6h, 500V = 7h).
Counting poles on industrial plugs and sockets: 3P / 4P / 5P explained
One model is written 3P on one page and "3-pole" on another — it is the same number, and the earth is always counted. With a table checked against the manufacturer datasheets (voltage and clock position included).
What people call industrial sockets: add-on = panel-mounted = flush-mounted
The same product has several names: add-on socket, panel-mounted socket and flush-mounted socket are the same thing, while wall-mounted is a different one. A full glossary so you quote the right model.
16A / 32A / 63A / 125A: how to pick the rating in three steps
The rating follows the equipment current with at least 20% headroom: 16A ≈ 7.5kW, 32A ≈ 15kW, 63A ≈ 30kW, 125A ≈ 60kW (three-phase 380V). With the conversion formulas and the four commonest mistakes.
