Since January 1, 2000, all PG cable gland sizes to DIN 40430 used so far are replaced by metric sizes to EN 60423 within the framework of European harmonisation. This switchover mainly affects bushings and sealing plugs, which are supplied as accessories with our enclosures. Cable glands with a metric thread comply with DIN EN 50262.

Accordingly, MENNEKES is switching all glands over to metric sizes. However some devices with PG cable glands may still be sold by dealers. Users have no obligation to retrofit the new units; therefore devices with PG cable glands may be installed and operated as before.

The following table offers information to facilitate conversion.

Metric thread	Typical sealing area	Typical capacity of terminal
M12	2.5 ? 6.5	3.0 ? 6.5
M16	2.5 ? 8.0	3.5 ? 8.0
M20	5.0 ? 12.0	6.0 ? 12.0
M25	9.0 ? 18.0	12.0 ? 18.0
M32	14.0 ? 25.0	17.0 ? 25.0
M40	18.0 ? 32.0	20.0 ? 32.0
M50	24.0 ? 38.0	26.0 ? 38.0
M63	30.0 ? 44.0	30.0 ? 44.0
