DESCRIPTION
The Capacitive Touch Sensor TTP223B outputs a LOW signal in the default state. When a finger touches the sensor, the sensor outputs a HIGH signal. If not touched for 12 seconds, the sensor automatically switches to low-power mode.
The maximum sensing distance can reach up to 4mm, which can be widely used in touch switch control of various acrylic panels, casings, and thin wood boards. The working voltage is 3V - 5.5V DC.
You can use this sensor behind surfaces such as plastic, glass, or non-metallic materials. As long as your finger comes close enough, not necessarily touching, the sensor will pick up and trigger output.
TECHNICAL DETAILS
- Input Voltage: 3V - 5.5V
- Detection Distance: Up to 4mm
- Dimensions: 24mm x 24mm x 7.2mm
