    FAQ<\/h2>\n

    Q1: What is the function of the SL-73A1 sensor?<\/strong>
    \nA:<\/strong>\u00a0The SL-73A1 detects the position or status of a compatible elevator component through magnetic proximity sensing.<\/p>\n

    Q2: What does NO mean?<\/strong>
    \nA:<\/strong>\u00a0NO means Normally Open. The output contact remains open in the normal state and changes status when the sensor detects the corresponding magnetic target.<\/p>\n

    Q3: What is the operating voltage of this sensor?<\/strong>
    \nA:<\/strong>\u00a0The specified operating voltage is 24\u201348VDC. Please confirm that the elevator control system provides a compatible DC voltage before installation.<\/p>\n

    Q4: How can I confirm whether the SL-73A1 is suitable for my elevator?<\/strong>
    \nA:<\/strong>\u00a0Please compare the model number, output type, voltage, wiring, sensing distance, and mounting structure with your original sensor.<\/p>\n

    Q5: Can you help confirm the correct model if I am not sure?<\/strong>
    \nA:<\/strong>\u00a0Yes. Please send clear photos of the original sensor, product label, wiring, magnetic target, and installation position. Our technical team can help identify the correct model.<\/p>\n

    Q6: Do you supply other elevator sensors and spare parts?<\/strong>
    \nA:<\/strong>\u00a0Yes. We supply magnetic proximity sensors, photoelectric switches, load sensors, PCBs, buttons, and other elevator spare parts.<\/p>\n","protected":false},"excerpt":{"rendered":"
