Gear Tooth Sensors

The Series P5000 Hall Effect Gear Tooth speed sensor is a non-contact, solid state ferrous detecting device with a switched output. Its unique design provides a low-cost solution for a wide range of speed sensing applications, especially those requiring true zero speed performance. This device utilizes a Hall Effect sensor that is internally biased with a rare earth permanent magnet and detects the interaction from an external ferrous target. Unlike earlier Hall-based products, this device automatically detects changes in target position or symmetry and “self-adjusts” to compensate for these changes. This specialized feature eliminates the need to externally calibrate or mechanically adjust each sensor for optimum performance. In addition, electronic hysteresis built into the device eliminates false triggering due to mechanical backlash and vibration. Installation of this sensor is also easier than “dual element” versions, as this device operates correctly regardless of its rotational position or alignment relative to the motion of the target.
