GT2-A32 Keyence Digital Contact Sensor Head | Air Push, 32 mm Stroke
GT2-A32 is a high-accuracy digital contact sensor head from the Keyence GT2 series. It uses an air push type design. The stroke length is 32 mm. The sensor uses the Scale Shot System. This system is absolute type. It has no tracking error. It connects to a GT2 series amplifier. The M8 connector makes installation easy. This sensor suits inline measurement and position checking.
Core selling point: 0.5 µm resolution, 3.5 µm indicated accuracy, and 1 ms sampling cycle. These features give stable data for fast production lines.

Installation Guide
- Mount the GT2-A32 in downward, side, or upward position.
- Check measuring force for each position. Downward: 2.1 N. Side: 1.8 N. Upward: 1.5 N.
- Use dry air only. Keep pressure between 0.25 and 0.50 MPa.
- Do not exceed 1 MPa pressure resistance.
- Connect the M8 connector to a GT2 series amplifier.
- Keep the probe aligned with the target surface.
- Avoid strong vibration and sudden impact.
Setup and Maintenance
- Setup is simple. The absolute system needs no tracking adjustment.
- The 2-colour LED shows status clearly. Green and red states are easy to read.
- Clean the probe and air line at regular intervals.
- Use clean, dry air to prevent moisture and oil build-up.
- Check the M8 connector for tight fit and clean pins.
- Replace worn contact parts before accuracy drops.
Compatibility
- Works with Keyence GT2 series amplifiers.
- Uses an M8 connector for signal transfer.
- No built-in communication port or protocol.
- No communication expansion module.
