The K4 Gear Tooth Sensor a non-contact, solid state ferrous detecting device with a switched output. Incorporating a unique design ensures this sensor provides a low cost solution for a wide range of speed sensing applications, especially those requiring true zero speed performance. The K4 Gear Tooth Sensor utilises 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 compensates for these changes. This specialised 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 K4 Gear Tooth Sensor Enquire Now
