Product specifications 

Name 

: Screw-in heater 

For technical details see order confirmation. 

 

Note: 

Cable gland temperature range  

: -20°C (dynamic) to +100°C.  

 

  -40°C (static, briefly) 

 

The cable glands can be used at temperatures of between -20°C and -40°C only if static stress is 

present at the place of use. Static stress means that no other forces (impact, tension, pressure, etc.) 

may act on the correctly mounted cable gland and its correctly installed line. 

The screwing point, cable gland and inserted line must be in an idle position. A fixed cable gland must 

be used. Instead of considering the cable gland as just a stand-alone component, the user must take 

the sum total of the prevailing ambient conditions into account at the place of use. 

At temperatures below -40°C, the sealing ring material CR/NBR starts to harden significantly and the 

polyamide PA6 used tends to become brittle. 

 

 

Temperature recording 

The units must not be operated without appropriate temperature recording.  

Install a suitable temperature control and/or limit on site if this is not installed by the manufacturer. 

Refer to your order confirmation for the setting values.
