SHE

Technical Documentation

Today's molding processes require a thorough monitoring system for a fully automatic operation. Disruptions need to be automatically detected and transferred to the machine control.

The function of our shut-off nozzle is monitored by the type SHE sensor. The sensor is integrated in the hydraulic or pneumatic actuator and detects the end position of the piston. From both signals the shut-off condition “open” or “closed” can be derived and passed on to the machine control through the signal amplifier.

 

Criteria:
• compact design
• repeat-exact, non-contact detecting of piston position
• continuous trouble free operation up to 155°C
• Signal amplifier with switch display

Retrofit:
All Herzog shut-off nozzles can be retrofitted in minutes by replacing the actuator and extending with Hall sensors, signal amplifier and connection cables.
