GT-H22 Digital Contact Sensor Head by Keyence
GT-H22 is a standard digital contact sensor head from the Keyence GT series. It uses LVDT technology for stable displacement measurement. The 22 mm stroke suits many industrial gauging tasks. It connects to a GT series amplifier for power and signal output. The head has no built-in ports or protocols. This keeps the sensor compact and durable. The IP67 protection rating supports use in harsh factory environments. It works well for position checks, thickness measurement, and automated inspection.

Installation Guide
- Mount the GT-H22 on a rigid fixture. Avoid vibration and side load.
- Keep the stroke within 22 mm. Do not force the probe beyond its range.
- Check measuring force direction. Downward, side, and upward values differ.
- Connect the cable to a compatible GT series amplifier.
- Use the correct amplifier settings for response and output.
- Protect the cable from sharp edges and moving machine parts.
- Keep the sensor within -10 to +55 °C during operation.
Setup and Maintenance Convenience
The GT-H22 is easy to integrate. It has no internal communication settings. All setup happens on the GT amplifier. This saves time during commissioning. The IP67 body resists dust and water. Regular cleaning helps maintain repeatability. Check the probe tip for wear. Verify cable condition before each production run. Replace the head if impact damage occurs.
Compatibility Notes
The GT-H22 works only with Keyence GT series amplifiers. It does not include built-in ports or protocols. It does not need separate power wiring. The amplifier supplies power and reads the LVDT signal. Confirm amplifier model and cable length before purchase. This head is a direct replacement for standard GT series contact sensor applications.
Certification and Compliance
Official certification documents are available on request. The product page confirms active Keyence production status. IP67 rating supports protection against dust and water ingress. Please contact us for specific compliance needs. We can help verify documents for your project.
