SPA1-Q Magnetic Induction Switch Product Overview: SPA1-Q, SPA1-S, and SPA1-N magnetic induction switches are long-distance magnetic switch products. This product uses giant magnetoresistance (GMR) magnetic sensing elements. The product mainly determines the output level based on the size and direction of the magnetic field measured by the GMR chip. The product is ready for use upon power on, with switch output, and can also be customized according to customer requirements. SPA1-Q Magnetic Induction Switch Principle Technical Parameters Measurement Distance:Φ 20 * 10mm rubidium iron boron magnetic steel induction distance can reach up to 20cm. Working voltage: 5~24V. Frequency response: C to 100kHz. Continuous working temperature: -40 ℃~105 ℃. SPA1-Q: Measure the size of the magnetic field (both N and S levels are acceptable). SPA1-S: Measure the size of the S-level magnetic field. SPA1-N: Measure the size of the N-level magnetic field. Product instructions: When the magnetic steel is far away, the level output and indicator light will turn off. When the magnetic steel approaches a certain distance, the level output and indicator light will light up. Wiring Definition: Red - Voltage Positive (Vcc); Black - Power ground (GN)- Output (Vout). 01 size and debugging: diameterΦ 12mm, length 30mm. The distance is not adjustable. Measure distanceΦ The induction distance of 20 * 10mm rubidium iron boron magnetic steel is 10cm. 02 size and debugging: diameterΦ 18mm, length 60mm. When debugging, use a non-magnetic screwdriver (non ferrous) to rotate the potentiometer (or test again when the ferrous screwdriver rotates and leaves a distance of more than 7cm). Potentiometer debugging: Rotate the potentiometer clockwise to increase the testing distance, and adjust it until the red indicator light at the end of the sensor lights up. At this point, the testing distance reaches infinity;. Rotate counterclockwise to reduce the testing distance. The output level is indicated by an indicator light, with the light off indicating the output level and the light on indicating the output level. 03 size and debugging: 70mm * 62mm * 28m square box with ears. When debugging, use a non-magnetic screwdriver (non ferrous) to rotate the potentiometer, or test again when the ferrous screwdriver is rotated and moved away from a distance of more than 7cm. Potentiometer debugging: Rotate the potentiometer clockwise to increase the testing distance, and adjust it until the red indicator light at the end of the sensor lights up. At this point, the testing distance reaches infinity. Rotate counterclockwise to reduce the testing distance. The output level is indicated by an indicator light, with the light off indicating the output level and the light on indicating the output level. Attention: Magnets (magnetic sources above 100mT) may cause measurement distance errors within 1cm. Please pay attention when debugging and installing. nine hundred
