      Self-generating passive magnetic speed sensor

      70085-1010-412

      Product Information:

      70085-1010-412 is a self-generating passive magnetic speed sensor for detecting the passage of ferrous gear teeth or similar targets. It produces an AC signal whose frequency follows target speed.

      The official selection guide lists a 5/8-18 threaded body, 6.0-inch threaded length, 7.25-inch overall sensor length, wire termination, 13.4 V peak-to-peak guaranteed output and a -65 to +95 °C temperature range.

      The published output guarantee is based on a 0.030-inch air gap at 500 inches per second. Confirm target material, tooth geometry, minimum speed, air gap, load impedance, wiring and signal-input requirements before installation.

      • Wire Termination
      • 13.4 V Peak-to-Peak Guarantee Point

      AI-Tek Instruments 70085-1010-412 is a passive variable-reluctance speed sensor that generates an AC signal as ferrous target teeth pass its magnetic pole piece. Signal frequency corresponds to rotational speed and signal amplitude depends on speed, air gap and target geometry.

      This configuration has a 5/8-18 thread, 6.0-inch threaded length, 7.25-inch overall length and wire termination. The official guaranteed output is 13.4 V peak-to-peak at a 0.030-inch air gap and 500 inches per second.

      The 70085-1010-412 Bently Nevada passive magnetic speed sensor may be supplied and supported by Moore Automated according to the stated OEM lifecycle and confirmed stock condition.

All prices are shown in USD.

      Output Characteristics:

      • Self-generating variable-reluctance operation
      • 13.4 V peak-to-peak guarantee point
      • 0.030 in published test gap
      • 500 in/s published test speed
      • Output frequency follows target speed

      Available output depends on surface speed, air gap, target size and the connected load impedance.

      Mechanical Configuration:

      • 5/8-18 mounting thread
      • 6.0 in threaded length
      • 7.25 in overall length
      • Wire termination
      • -65 to +95 °C rating

      Verify the mounting depth, target path and available clearance before installing the long-body sensor.

      Application Guidance:

      • Use a ferrous toothed target
      • Minimize the air gap without contact
      • Match pole-piece size to target pitch
      • Use a high-impedance signal input
      • Check output at minimum and maximum speed

      Commission the installation by checking waveform amplitude, frequency and clearance across the full operating-speed range.
