Cable gland

Limited temperature range of the M20 × 1.5 plastic cable gland
for explosion protection variants.
The permissible ambient temperature range of the cable gland is
−20 to 80 °C (−4 to 176 °F). When using the cable gland, make
sure that the ambient temperature is within this range. The
cable gland must be installed in the housing with a tightening
torque of 3.8 Nm. When installing the connection of the cable
gland and cable, check for tightness to ensure that the required
IP rating is met.
