Hafner ST 222 V24 is a solenoid coil connector plug for MA 22 Form B plug-in coils. Its interface is Form B (industry pattern) and its electrical range is 24 V ±10% with a 10 A maximum current. A red LED and varistor are included. Match the contact pattern, cable connection and mounting arrangement to the installed coil or terminal.

Key product details

  • Manufacturer: Hafner
  • Product code: ST 222 V24
  • Part type: solenoid coil connector plug
  • Interface: Form B (industry pattern)
  • Compatible equipment: MA 22 Form B plug-in coils
  • Operating voltage: 24 V ±10%

  • Assembled protection: IP65 for the assembled coil and connector with the supplied flat seal, screw and nut

Interface and indication

This Form B (industry pattern) plug mates with MA 22 Form B plug-in coils. Its red LED gives a local indication at the specified 24 V ±10% connector supply, while its varistor provides suppression of the switching transient. Match the coil supply and connector indication rating before use; the connector does not change the coil’s own voltage or power. The housing accepts M16 × 1.5 cable entry, 6–8 mm cable diameter; the cable is prepared and terminated during installation.

Selection and installation

Check the coil contact layout against Form B (industry pattern) and select its actual supply voltage before ordering ST 222 V24. The listed 24 V ±10% is the indicator rating, not permission to energise a coil outside its nameplate rating. The connector is rated up to 10 A; the connected load and wiring must remain within the ratings of the complete circuit. IP65 refers to the correctly assembled compatible coil and connector with the supplied seal and fasteners, not to the unplugged connector by itself.

Mate ST 222 V24 to the intended coil, fit the seal and secure the screw and nut as specified by Hafner. Route suitable field cable through the M16 × 1.5 cable entry, 6–8 mm cable diameter, terminate it to the installation wiring diagram and secure the cable entry. Commission the solenoid at its coil-rated supply and check that the valve changes state. The coil and valve are selected separately from this connector.
