Abstract
A solenoid valve has an electromagnet with a coil, an RFID tag for identifying the solenoid valve, and an antenna for unidirectional or bidirectional communication with the RFID tag. The antenna is the coil of the electromagnet. Using the coil of an electromagnet for communication with an RFID tag permits inexpensive quality assurance when using solenoid valves, in particular in blow moulding machines.
