XS12JK-3P/Y motor speed sensor speed probe

1、 Introduction:

Performance Characteristics

1. Non contact measurement, without contact with the tested rotating parts and without wear

2. Adopting the principle of magneto electric induction, no external working power supply is required, the output signal is large, no amplification is needed, and the anti-interference performance is good

3. Adopting an integrated design, the structure is simple and reliable, with high anti vibration and anti impact characteristics

4. Adapt to a wide temperature range in the working environment, suitable for harsh industrial environments such as smoke, oil and gas, and water and gas environments

XS12JK-3P/Y speed sensorIt is a cost-effective and versatile universal speed sensor used for measuring the speed of magnetic objects, using non-contact measurement methods. The sensor is composed of magnetic steel, soft magnetic armature, and coil inside. The basic measurement principle is that the magnetic field (magnetic lines) is emitted by a magnet and passes through the armature and coil. When a magnetic object approaches or moves away, the magnetic flux in the coil changes, and the coil induces a change in electromotive force. The speed measuring gear on the inner shaft of the coil induces a frequency signal proportional to the rotational speed; If it is an involute gear, the induced voltage is a sine wave. The amplitude of the signal is directly proportional to the rotational speed and inversely proportional to the gap between the probe end face and the tooth tip.

2、 Electrical indicators:

• DC resistance: 250 to 550 Ω (25 ℃)

• Working temperature: -30 to+100 ℃

3、 Physical indicators:

• Weight: Approximately 120g

• Anti vibration: 20g

• Thread specification: M16 × 1

• Installation gap: 0.5-1.0mm, recommended 0.8mm

• Material: 304 stainless steel

• Gear material: Gear materials should be made of metal materials with strong magnetic permeability.

• Tooth shape：Forming an involute tooth profile is the most suitable tooth profile. Using large modulus gears or other tooth profiles will result in significant waveform distortion, which will hinder accurate measurements. If the spindle has axial movement, it should be noted that the center of the magnetic pole should be at the center position of the gear.

Gear module: 2 to 4 tooth width b: greater than 5mm.
