Technical specifications

Sun offers explosion proof coils for use in hazardous environments. Certification requires the explosion proof coil to be sold as a complete cartridge/coil assembly. Coil cannot be purchased separately. For ordering information, please see the coil option section on the applicable cartridge product page.

  • CSA certified (C and US)
  • NEC 505: Class I, Zone 1, AEx mb IIC T3
  • NEC 500: Class I, Division I, Groups A, B, C and D; Class II, Division I, Groups E, F, and G; Class III, Division I
  • CEC/CSA: Ex mb IIC T3
  • Certification requires the explosion proof coil to be sold as a complete cartridge/coil assembly. Coil cannot be purchased separately.
  • No arc suppression diodes in coil.
  • Coil windings utilize NEMA-MW-80, Class F (155 deg C) magnet wire.
  • For optimum proportional performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 80 - 250 Hz.
  • Ingression protection rating is IP67.
  • RoHS compliant. Restricted materials less than 0.1% total by weight.
  • The external steel shell is zinc plated with yellow dichromate. The coil nut is zinc plated with clear dichromate.
  • Non-resettable integral internal thermal and current fuse protected.
  • Coil must be installed on the cartridge with the proper orientation for proper performance. See drawing/instructions.

  • Coil/cartridge assembly can be mounted in any position, however, coil orientation on cartridge assembly is critical. Arrows on coil label must face towards coil nut.
  • Coil cannot be purchased separately and must be configured along with the cartridge valve. Please see the applicable cartridge product page for ordering information.
  • Sun's explosion proof coil requires more clearance than 770 series coil. Sun manifolds with more than one cavity may not allow enough clearance for explosion proof coils.
  • For proportional valve applications, the maximum current of 590mA has been established so a proportional valve can function optimally under a variety of ambient temperatures.
