General product information
The asterisks in the type designation HSK-M-Ex 1610.****.**, HSK-M-EMV-Ex 1616.****.**, HSK-M-EMV-D-Ex 1631.****.**, HSK-MZ-Ex 1611.****.**, HSK-MZ-EMV-Ex 1617.****.**, HSK-INOX-Ex 1612.****.**, HSK-INOX-EMV-Ex 1672.****.**, HSK-M-Multi-Ex 1687.****.**, HSK-M-FLAKA-Ex 1689.****.** of the cable entries will be replaced by digits to describe the colour, the thread dimensions and the accompanying diameter range of the cable.
The cable entries type are designed for the installation at electrical apparatus type of protection increased safety “e” and serve for the installation of fixed cables.
The types HSK-MZ-Ex and HSK-MZ-EMV-Ex may also be used for the installation of non fixed cables. The cable entries are suitable for the application in areas potentially hazardous by combustible gases and dusts.
Permitted temperature range -20 °C ≤ Ta ≤ +95 °C

Special condition for safe use
The cable entries type
HSK-M-Ex 1610.****.**
HSK-M-EMV-Ex 1616.****.**
HSK-M-EMV-D-Ex 1631.****.**
HSK-INOX-Ex 1612.****.**
HSK-INOX-EMV-Ex 1672.****.**
HSK-M-Multi-Ex 1687.****.**
HSK-M-FLAKA-Ex 1689.****.**
shall only be used for fixed installations.
The ambient temperature range of electrical apparatus is normally limited to -20 °C ≤ Ta ≤ +40 °C.
The ambient temperature range can be exceeded for the use of these cable entries as long as the permitted temperature range of -20 °C ≤ Ta ≤ +95 °C of the cable entries is taken into account.
