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.
This particular revision of the 1129 has a new sensing chip that recalibrates after 45 seconds of contact (as opposed to 60 seconds on the previous revision). Other than that, this sensor will function the same as the 1129_0.
Keeping in mind the various requirements of the customers, we are involved in offering best quality of Touch Sensor. These Touch Sensors are extensively used and in many other suitable applications. Touch Sensor is extensively used in many lamps and wall switches that have a metal exterior as well as on public computer.
