Keyence GT2-H32L Sensor Head | 32mm 0.5µm

Keyence GT2-H32L Contact Sensor Head

Product Introduction

The Keyence GT2-H32L belongs to the GT2 series of high-accuracy digital contact sensors. This box-type sensor head provides a 32 mm measuring range with 0.5 µm resolution. Its indicated accuracy reaches 3 µm (p-p), ensuring reliable measurement for demanding industrial applications.

This model features a low measuring force design. Force varies by mounting orientation: 1.2 N downward, 0.9 N side, and 0.6 N upward. Consequently, the GT2-H32L suits delicate workpieces that cannot tolerate high contact pressure.

Technical Specifications

The sensor employs a Scale Shot System with an absolute detection method. Furthermore, this absolute design eliminates tracking errors and requires no reset after power loss. The 1 ms sampling cycle supports fast data acquisition.

Detection and Performance

• Detection System: Quartz glass scale, CMOS image sensor, absolute type

• Measuring Range: 32 mm

• Resolution: 0.5 µm

• Indicated Accuracy: 3 µm (p-p) at 20°C

• Sampling Cycle: 1 ms

• Indicator Material: Polyarylate

• Contact Material: SUS304, SUS440C stainless steel

• Weight: Approx. 270 g (excluding cable)

Installation Guide

Proper mounting ensures measurement accuracy. The sensor head connects to GT2 series amplifiers through an M8 connector. Notably, the GT2-H32L does not include a dust boot.

For upward-facing installation, always use the mounting holes on the side of the sensor head. If you use mounting bracket D in this orientation, the spindle may not fully extend. Additionally, the L-shaped M8 connector (GT2-CHL*M) is not compatible with this model.

When connecting the cable, insert the connector straight and tighten securely. The recommended tightening torque is 0.4 to 0.5 N·m. Finally, for high-accuracy measurements, use a dedicated mounting jig to avoid surface roughness effects.

Packaging List

• 1x Keyence GT2-H32L Sensor Head
