Hall Effect Speed Sensors
DH & RH Series

aitek instrument hall effect speed sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect sensors for engine timing applications and has developed a line of durable products for industrial use.

With multiple standard variations we offer the widest range of standard catalog sensors to meet your various design needs. The design is flexible to easily meet all of your application requirements.

The Hall Effect sensor can sense each change in target movement, regardless of speed, from near zero to 15 kHz frequency range, generating a steady pulse train of frequency proportional to target speed. Typically, each time a gear tooth (or any ferrous discontinuity) passes in front of the sensor the output changes state. This type of sensor is known as a "P" type because it uses N-P-N transistor logic (as opposed to "N" type, which uses P-N-P transistor logic).

Key features to note are:

  • Reverse voltage protection, to prevent damage if mis-wired
  • Extended temperature range
  • Wide range of supply voltage
  • Two output options of Supply Tracking or TTL Compatible
  • Rugged design meeting IEC 77 Standards (European Railroad Applications)
