Omron Electronics W2GJ Touch Sensors

Omron Electronics W2GJ Touch Sensors are designed for effortless integration and offer reliable touch detection without the hassle of circuit design or sensitivity calibration. Its ability to sense changes in capacitance ensures stable operation across various applications. Typical Omron Electronics W2GJ Touch Sensor applications include lighting systems, elevator panels, vending machines, and faucets.

Features

  • Suitable for embedding in equipment
  • Enables touch sensor configurations to be created that suit user applications
  • Touch electrodes and touch sensor electrodes can be fastened just using screws
  • Body-to-electrode static electricity transfers can easily be prevented using FG terminal models (W2GJ-L6)
  • Supports 5VDC to 15VDC, with open-collector output
  • No need to perform sensitivity adjustments or design circuits, and thus minimizes development man-hours
  • Achieves stable operation using a touch electrode that changes capacitance depending on the level of touch
