Key Features and Benefits
- High accuracy: 1 µm accuracy with 0.1 µm resolution.
- Absolute measurement: No tracking error, no homing needed.
- Fast sampling: 1 ms cycle for real-time feedback.
- Low measuring force: 0.2 N upward, ideal for delicate parts.
- Rugged design: IP67 rating for harsh environments.
- Easy integration: M8 connector to GT2 amplifiers.
Installation Guide
Mount the GT2-H12KF in downward, side, or upward orientation. Each orientation has a specific measuring force. Use the M8 connector to link to a GT2 amplifier. Keep the sensor within -10 to +55 °C. Avoid condensation and freezing. The IP67 rating allows use in dusty or wet areas. No external power is needed; the amplifier supplies power.
Setup and Maintenance
Setup is simple. Connect the sensor to a GT2 amplifier. The absolute system removes the need for zeroing. The 2-colour LED shows operation status. Green means normal. Red indicates a problem. Clean the contact point with a soft cloth. Do not use solvents. Regular checks of the M8 connector ensure reliable signals. No calibration is required under normal use.
Compatibility
The GT2-H12KF works only with GT2 series amplifiers. It does not have built-in ports or protocols. All communication goes through the amplifier. This sensor is a direct replacement for existing GT2 setups. It supports obsolete control systems when paired with the right amplifier.
Certifications and Standards
This sensor meets IEC IP67 protection. It follows Keyence quality standards. The product is active and in production. Last verified: 2026-09. No additional certifications are listed.
