The solenoid coil is manufactured as a DC coil as standard. On request, solenoid coils can be fitted with an integrated reverse polarity protected diode for reducing the switch-off induction voltage, to protect against voltage surges.
Solenoid coils for connection to alternating current have an integrated bridge rectifier. For coils with a DIN connector to EN 175301-803 a corresponding connecting socket (Part No. 394287) can be supplied separately. As a general rule, special coils can be manufactured to customer specification. Please consult your sales partner. For the various connector electronics for coils, please see the relevant valve brochure.
