Touch Sensor

MODEL: 1129_1B

SGD $ 17.00

In Bulk
(per piece)

Detect a touch through up to 1/2" of glass or plastic with this low-cost capacitive sensor.

 

Note: The 1129_1B is identical to the 1129_1, except that you have the option of which size of Phidget cable to include.

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:
