QUADRATURE ENCODER

 

For positioning or bi-directional applications, the advanced Quadrature Sensor II gives you both motor shaft speed and direction. The Quadrature Sensor II provides two pulse-trains which are 90 degrees out of phase from each other. This phase difference provides direction information to a CONTREX controller. The Quadrature Sensor II technology is more rugged, reliable, and easier to mount than typical optical encoders.

 

• Sense speed and direction of ferrous geartooth targets (see Ring Kits)

• Wide operating temperature rating -40 to +125 degree Celsius

• Zero speed to 10,000 RPM shaft speed capability (100 kHz max frequency)

• Automatic gain adjustment to handle variable gaps when installed without Ring Kit

2X HALL EFFECT

 

For near zero speed applications, the 2X Hall Effect Sensor improves your ability to sense motor shaft speed at very low speeds. Unlike a magnetic pickup, the 2X Hall Effect Sensor is capable of sensing true zero speed while being tolerant of wider gaps. Additionally, the 2X Hall Effect Sensor improves the sensing resolution by 2 times, thus producing a 120 pulse-per-revolution signal when sensing a 60 tooth gear. This additional resolution improves motor speed control a low speeds.

 

• Sense speed of ferrous geartooth targets (see Ring Kits)

• 2 times the resolution of the geartooth target for better low speed control

• Zero speed to 10,000 RPM shaft speed capability (100 kHz max frequency)

• Automatic gain adjustment to handle variable gaps when installed without Ring Kit
