GT2-H12F Keyence Digital Contact Sensor Head
GT2-H12F is a high-accuracy digital contact sensor head from the Keyence GT2 series. It uses the Scale Shot System. This absolute design removes tracking error. The 12 mm stroke suits precise position and thickness checks.
The box-type body fits tight fixtures. A low-stress contact tip protects soft or delicate parts. The sensor head connects to a GT2 series amplifier through an M8 connector. It has no built-in communication port. All signal processing happens in the amplifier.
Core value: 0.5 µm resolution, 1 ms sampling, IP67 protection, and stable readings in industrial cells.

Installation Guide
- Mount the GT2-H12F on a rigid bracket. Keep the stroke path free from side load.
- Use the correct measuring force for the mounting direction. Downward mode gives 0.4 N. Side mode gives 0.3 N. Upward mode gives 0.2 N.
- Connect the M8 plug to a compatible GT2 series amplifier. Hand-tighten the connector.
- Keep the cable away from drives, relays, and high-current lines. This reduces electrical noise.
- Protect the contact tip from impact. A soft target may need a lower force setting.
Setup and Maintenance
- Zero the amplifier after mounting. Then check the full 12 mm stroke.
- Use the 2-colour LED for quick status checks. Green means normal. Red means attention.
- Clean the spindle and contact tip with a dry, lint-free cloth.
- Do not push the spindle past the mechanical end. This can damage the scale.
- Check the M8 connection each service cycle. Loose plugs cause unstable readings.
Compatibility
The GT2-H12F works with Keyence GT2 series amplifiers. It uses an M8 connector. It has no direct PLC, IO-Link, or fieldbus output. The amplifier provides power, display, and output signals. This head is a direct replacement for GT2 systems that use the same 12 mm box-type head.
Certification and Packaging
- Protection: IP67 according to IEC.
- Quality check: Tested before shipment.
- Packaging: 1 x GT2-H12F sensor head. Cable and amplifier are not included unless stated.
- Warranty: 12-month warranty.
- Shipping: FedEx, UPS, and DHL.
Typical Applications
- Thickness measurement on soft parts.
- Height and step checks in small assemblies.
- Position feedback on fixtures and stages.
- Wear and gap checks on production tooling.
- In-line inspection where 0.5 µm resolution is needed.
Diagnostic Capability
The absolute Scale Shot System reports position without tracking error. The 2-colour LED shows basic status. The connected amplifier handles detailed diagnostics. It can show signal level, tolerance limits, and error states. The 1 ms sampling cycle helps catch fast events. IP67 body protection supports use in wet or dusty areas.
