GT2-H12 Digital Contact Sensor – Precision Measurement for Industrial Automation
The GT2-H12 is a high-precision digital contact sensor designed for demanding industrial environments. It combines a quartz glass scale with a CMOS image sensor and an absolute projection system. This design eliminates tracking errors and ensures reliable measurements.
With a 12 mm measurement range and 0.5 μm resolution, the sensor delivers accurate results for fine positioning and inspection tasks. The 1 ms sampling rate and 10 Hz mechanical response support fast production cycles.
The 2-color LED (red and green) gives clear visual status feedback. The IP67 enclosure rating protects against dust and water. This makes the sensor suitable for harsh factory conditions.

Expert Review / Manager’s Insight
Manager’s Insight: The GT2-H12 stands out for its absolute measurement system. No tracking error means less downtime and fewer recalibrations. The 0.5 μm resolution is rare in this price class. The IP67 rating and robust zinc die-cast body handle coolant, dust, and vibration. This sensor is a smart choice for automated assembly, quality control, and micro-positioning.
Installation Guide
- Mount the sensor in downward, side, or upward orientation. Note the measuring force changes: 1.0 N, 0.9 N, or 0.8 N.
- Connect the M8 connector to the optional sensor head cable.
- Ensure the contact tip aligns with the target surface.
- Do not exceed the 12 mm measuring range.
- Keep ambient temperature between -10 and +55 °C.
- Avoid condensation and freezing.
Debugging and Maintenance Convenience
- The 2-color LED gives instant pass/fail status.
- Absolute system needs no re-zeroing after power loss.

FAQ
Q: What makes this sensor different from standard contact sensors?
A: It uses an absolute quartz glass scale and CMOS image sensor. No tracking error means you never need to re-home after power loss.
Q: Can I use it in a wet environment?
A: Yes. The IP67 rating protects against dust and water splashes. Do not submerge it.
Q: How often should I calibrate?
A: The absolute system rarely needs calibration. For critical applications, verify once per year.
Q: What cable do I need?
A: An optional M8 connector cable. Order it separately. We recommend a shielded cable for noisy factories.
Q: Is the measuring force adjustable?
A: No. It depends on mounting orientation. Downward gives 1.0 N, side gives 0.9 N, upward gives 0.8 N.
Q: What is the sampling rate?
A: 1 ms. This means 1000 readings per second.
Q: How do I know if the sensor is working?
A: The 2-color LED shows red or green. Green usually means target within range.
Q: Can I use it with a PLC?
A: Yes, if your PLC accepts digital sensor input. You may need a GT2 series controller.
Q: What is the smallest object it can detect?
A: The resolution is 0.5 μm. So it can detect very small changes in position.
Q: Is the contact tip replaceable?
A: The contact is made of TYPE304 and 440C stainless steel. It is not user-replaceable. Handle with care.
Purchasing Guide
- Check your controller compatibility. GT2 series is required.
- Order the M8 cable if you do not have one.
- Choose mounting orientation based on needed measuring force.
- For high-vibration areas, use additional damping.
- Buy from authorized sellers to get the 12-month warranty.
- For urgent needs, ask about 12–24 hour dispatch and FedEx/UPS/DHL options.
