Working principle of TL10-40A120F-GCAC220V temperature resistant, waterproof and oil proof proximity switch: The vibration coil behind the induction surface of the proximity switch generates an alternating electromagnetic field. Any conductive material entering this magnetic field will absorb the noise from the oscillation circuit and generate eddy currents. Then, the attenuation of the oscillator is converted into a switching signal in the output amplifier. Based on this functional principle, all metals can be detected, regardless of whether they are moving or not. The temperature sensing switch is not affected by the operating environment of the sensor due to the fact that the frequency magnetic field is not affected by temperature and the magnetic properties inside the detected object. Performance characteristics of temperature proximity switches: 1. To avoid damaging the proximity switch during installation, do not exceed the given tightening torque. Stainless steel thread m5=2nm m8=10nm m12=20nm m18=55nm m30=200nm
2. Induction zone/induction surface. The induction zone is located in the front of the induction surface. In the induction zone, the proximity switch reacts to the nearby metal components, changing the output state.
3. Rated sensing range (sn): The distance at which the switch output state changes when the metal component approaches the sensing surface of the switch is the rated sensing range. 4. Repeatability: The repeatability of two measurements under certain conditions. The difference in the measured values should be less than 10].
5. Output function: Closed contact (no): Object in sensing area - Switch output open contact (nc): Object in sensing area - Switch suppression
6. LED display device's ambient temperature reaches+130° When c, there will be an LED status When the LED light is no longer on, it indicates that the temperature has reached *. Through this process, the equipment can be protected from damage. 7. Start delay time: The time interval between the moment when the switch is turned on and when it is ready to output a normal signal (within ms milliseconds).
8. Correction factor: If a material different from steel (1.0037) is used, the correction factor specifies the change in detection distance. The correction factor depends on the type, characteristics (internal structure), size, and geometric shape of the material being detected. 9. Typical correction factor: st: 1 v2a: approximately 0.6 ms: approximately 0.3 ms: approximately 0.2 copper: approximately 0.15 steel sensor correction factor: v2a: 0.5 ms: approximately 0.1 aluminum, in order to establish an approximate induction range different from the ST37 material, bixu multiplies the induction range of ST37 by the corresponding correction factor. 10. Reverse polarity protection: If the connection terminals are reversed, a built-in protection can prevent damage to the proximity switch. 11. Short circuit protection: In case of current overload, there is a built-in protection to prevent damage to the proximity switch.
12. Switching point drift: Switching points change due to changes in the environment. Attention: 1. It is strictly prohibited to wire when the power is turned on, and the wiring should strictly follow the color markings on the wiring diagram.
2. The distance between the switch sensing surface and the measured body should be within 80% of the rated operating distance to ensure reliable operation of the switch. 3. Proximity switches are generally not suitable for series or parallel use. If necessary, it is recommended to use intermediate relays in series or parallel to drive the load. 4. The DC type switch bixu uses a DC stabilized power supply with a voltage ripple of less than 10] (vpp).
5. Binary switches (whether DC or AC) should be connected to the power supply after passing through the load, otherwise the switch will be damaged< br />6、 The working voltage of the temperature proximity switch is not allowed to exceed its specified value.
