Installation Guide
Mount the GT2-H12K in downward, side, or upward position. Each orientation has a defined measuring force. Use the M8 connector to link the head to a GT2 amplifier. Keep the cable free from sharp bends. Confirm the mounting surface is stable. Tighten the fixture to reduce vibration. Check the LED indicator after power-up.
Setup and Maintenance
Setup is simple through the GT2 amplifier. No internal calibration is needed in the sensor head. Clean the contact area with a dry, soft cloth. Do not use solvents. Check the cable and connector for damage. Keep the unit within the stated temperature and humidity limits. The IP67 body supports washdown areas, but the connector must stay dry.
Compatibility
The GT2-H12K works with Keyence GT2 series amplifiers. It uses an M8 connector. It does not have built-in ports or protocols. All signal conversion happens in the amplifier. Use original Keyence cables and amplifier modules for best results.
Certifications and Compliance
The sensor head carries an IP67 (IEC) protection rating. Keyence confirms active production status. Last verified: 2026-09. For specific compliance documents, contact info@oiltechcontrols.com.
