Technical specifications

This 740 Series Coil configuration uses a connector adapter kit to provide the required termination.

  • Model code 740828LD includes coil 740928LD and adapter cable 991717.
  • Coil windings utilize Class N, (392° F [200 °C] rated) magnet wire.
  • Power cable with mating connector is required and is not included with the coil.
  • The coil is magnetically symmetrical and can be mounted on the solenoid tube in either direction for best cable access without affecting performance.
  • Coil is fully RoHS compliant. Restricted materials less than 0.1% total by weight.
  • The external steel shell is zinc-nickel plated and provides 1000-hour salt fog protection.
  • Coil includes a transient voltage suppression (TVS) diode.
  • For optimum proportional performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 100 - 250 Hz.
  • Workmanship performed to IPC-A-620 Class 2
  • Stranded Black UL 3289CSA 18 Gauge Wire
