GND:\r\nPower \u0026amp; Signal Ground (Isolate from digital noise sources) . OUT: Digital\r\nOutput Signal: Default: Low at idle, High when touched (Direct Mode)\r\nConfigurable via solder jumpers: AB=00: Momentary High TTL (No-lock) AB=01:\r\nLatching High TTL (Self-lock) AB=10: Momentary Low TTL (No-lock) AB=11:\r\nLatching Low TTL (Self-lock) . FAQ Q1: First Power-On Unresponsive? A: Wait\r\n0.5s stabilization period (post-power-on). Avoid touching during this phase .\r\nQ2: False Triggers or Inconsistent Response? A: ① Adjust sensitivity via\r\nexternal capacitor (0–50pF); ② Ensure no metal\/EMI interference near sensor .\r\nQ3: Output Signal Stuck High\/Low? A: Verify solder jumper configuration (AB\r\npads): Desired momentary action → Set AB=00 or AB=10. Desired latching action\r\n→ Set AB=01 or AB=11 . Q4: Can It Work Behind Walls? A: Yes! Mount behind\r\nplastic\/glass ≤5mm thickness.
