Speed and Direction Sensors

Speed and direction sensor or Gear tooth sensor or magentic pickup to count gear teeth as well as direction of motion of gear wheel with incremental quadrature output. upto as high speed as 15K hz in Full Metal Casing or Automotive type Plastic casing

  • Speed and Direction sensor is based on magnetic Hall's effect Technology.
  • GTS-DO is Dual Output Magnetic Proximity sensor such that channel A lags or leads Channel B if used along with a gear wheel.
  • The signal of the channel goes high with leading edge of tooth and goes low on trailing edge of the gear GTS-DO is used to detect the direction as well as speed using a gear wheel. Hence we can consider that GTS-DO along with A gear wheel can simply replace a Optical encoder.
  • The main USP of the Product is it is IP67 protected with Extremely High speed functional capability upto 15kHz and upto zero speed on lower end .
