The 1129 is a capacitive touch sensor and can detect a touch through plastic, glass, or paper. We recommend a material thickness of up to 1/2”.
The sensor can work as a close proximity sensor, sensing objects at a distance of up to 1/2” from the board in all directions without direct contact.
On the bottom side of the Touch Sensor there is a small exposed metallic pad. A soldered connection can be made to the pad to increase the size and dimensions of the touchable area, such as attaching the sensor to a metallic object or some wire.
The 1129_1B has a sensing chip that recalibrates after 45 seconds of contact (as opposed to 60 seconds on the 1129_0). Other than that, this sensor will function the same as the 1129_0. Please refer to the table below to see the differences:
