SZMB-5, SM-16, Hal-12-110 Speed ​​Sensors
TO3 series sensors use the principle of electromagnetic induction to achieve the purpose of speed measurement, with large output signals, no amplification, good anti-interference performance, no external power supply, can be used in the harsh environment of smoke, oil and gas, water vapor, gas and so on.
Second, technical data:
 1, output voltage: When the gear module is 4, the tooth 60, the material g3, the clearance is lmm
 1000 rev / min >5V (RMS)
 2000 rev/min >10V (effective value)
 3000 rev / min >15V (RMS)
 2, DC resistance:  130 ohms to 140 ohms (if the customer needs to use other resistance data, indicate when ordering)
3ã€Insulation resistance: >50MΩ at 500V DC
 4, working temperature: -20 °C ~ l20 °C
 5, Weight: About 100 grams (not including tail leads)
Third, the working principle:
When using, install a gear (positive, helical or grooved disc) on the shaft to be measured and install the sensor on the bracket. Adjust the gap between the sensor and the gear top to about 1mm.
When the shaft rotates, it drives the gear to rotate. According to the principle of electromagnetic induction, a pulse signal is generated at both ends of the internal coil of the sensor. When the shaft rotates one rotation, it generates Z voltage pulse signals according to the following formula:
 F=(n/60)×Z
Where: F is the frequency Hz/second
 n is the rotational speed of the shaft under test
Z is the number of gear teeth
First, use
SM22 magnetoelectric speed sensor can convert the angular displacement into electrical signals for counter counting. As long as it is non-contact, it can measure all kinds of magnetic materials such as gears, impellers, and the speed and line of holes (or slots, screws). speed.
The sensor has the advantages of small size, strong and reliable, long life, no need of power supply and lubricating oil, and can be matched with general secondary instruments.
Second, the principle
The sensor is composed of iron core, magnetic steel and induction coil. When there is a rotating magnetic gear (slotted shaft or disc, etc.) near the end face of the core, it will be generated in the induction coil due to the change of magnetic resistance in the magnetic circuit. Induced electromotive force, output approximate sine wave electrical signal.
Third, the basic parameters
 1. Output waveform: Approximate sine wave (≥50r/min)
 2. Output signal amplitude: ≥ 300mV, 50r/min, sensor core and measured gear tip clearance δ = 0.5mm,
Number of teeth  Z = 60,
Measured gear module m = 2 ,
The material is electrical steel,
The magnitude of the signal amplitude is proportional to the rotational speed and is inversely proportional to the size of the core and tip clearance.
 3. Measuring range: 50～5000Hz
 4. Use time: continuous use
 5.Working Environment: Temperature -20～+60?C
 6. Output form: X12K4P four-pin plug
 7. Overall dimensions: outside diameter M22×1
The Hal-12-110 Hall speed sensor is a speed sensor that uses the Hall principle. Its sensing object is magnetic steel. When the magnetic steel is embedded on the object to be measured, the pulse signal related to the rotation frequency is output by the sensor when the object to be measured rotates, which achieves the purpose of speed detection or displacement detection. Due to the ease of installation and use, good versatility, it has been widely used in various fields.

Mounting thread: M16×1 (can have other options), the length of the shell is more than 50mm
output signal:
Waveform: Speed ​​Pulse Waveform
Amplitude: output Vo=Ut-2.7)V at high level and ≤0.07V at low level
Outlet: Provides two ways to connect the terminal and direct cable:
1. The metal shield in the sensor output line should be connected to the earth zero line.
 2. It is not allowed to use and place in a strong magnetic field environment with a temperature of 25°C or higher.
 3. Strong impacts should be avoided during installation and transportation.
 4. When the measured shaft fluctuates greatly, attention should be paid to properly amplifying the gap to avoid damage.
5. The sensor is designed to be used in harsh environments, so it is sealed after assembly and commissioning and cannot be repaired.
