The manufacture of the solenoid coil is a DC coil as standard.
On request, it's possible to fit solenoid coils with an integrated reverse polarity protected diode for reducing the switch-off induction voltage, to protect against voltage surges.
Furthermore, solenoid coils for connection to alternating current have an integrated bridge rectifier. Therefore, for coils with a DIN connector to EN 175301-803, it's possible to supply a corresponding connecting socket (Part No. 394287) separately. So, as a general rule, the manufacture of the special coils can happen according to customer specification.
Please consult your sales partner. For the various connector electronics for coils, please see the relevant valve brochure.
