GT2-76N Keyence High Accuracy Amplifier Panel Mount Expansion Unit

GT2-76N Keyence Digital Contact Sensor Amplifier – High Accuracy, Panel Mount

The GT2-76N is a high-accuracy digital contact sensor amplifier from the Keyence GT2 series. It is built for panel mount and works as an expansion unit. The unit delivers a 0.1 µm display resolution. It is ideal for precise position and thickness measurement in automated lines. The NPN open collector output supports HH, HI, GO, LO, and LL judgments. This amplifier is a solid choice for engineers who need stable, repeatable measurement data.

The GT2-76N does not include built-in communication ports. You can add communication via optional GT2 series communication units. This keeps the design flexible for different control systems. The unit runs on 10 to 30 VDC and consumes 2,200 mW or less. It operates from -10 to +50 °C with 35 to 85 % RH. The package weighs about 140 g with the panel bracket, front cover, and power cable.

Measurement Range and Frequency Response

The GT2-76N covers a wide display range. It reads from -199.999.9 to 199.999.9. The 0.1 µm resolution helps detect small changes. Response time is selectable. You can choose from hsp(3) to 1,000 ms. With GT2-Pxxx heads, response time extends to hsp(4,000) ms. This makes the unit suitable for both fast sorting and slow, stable measurement.

Sensitivity, Linearity, and Anti-Interference

The amplifier uses a high-accuracy digital contact method. It provides stable sensitivity for repeated measurements. Linearity depends on the connected GT2 sensor head. The unit is designed for low noise in industrial settings. The NPN open collector output handles 40 V / 50 mA or less. Residual voltage stays at 1 V or less. This supports reliable signal transfer to PLCs and controllers.

Environmental Durability

The GT2-76N works in -10 to +50 °C areas. It tolerates 35 to 85 % RH without condensation. The unit is not rated for freezing conditions. It fits clean factory floors, inspection benches, and automated stations. For harsh environments, use a proper enclosure.

Installation Guide

The GT2-76N is a panel mount expansion unit. It installs next to other GT2 amplifiers. Use the included panel mounting bracket. Connect the power cable to a 10 to 30 VDC supply. Keep ripple within 10 % p-p. Wire the control inputs for timing, preset, reset, or bank selection. Use no-voltage contacts for these inputs. Connect the NPN output to your PLC or indicator. Make sure the load does not exceed 50 mA. Check polarity before power on.

Setup and Maintenance Convenience

The GT2-76N offers simple panel access. You can set response time and judgment levels from the front panel. The display shows readings clearly at 0.1 µm resolution. Maintenance is low. Keep the front cover clean. Check cable connections at regular intervals. Replace the power cable if damage appears. No special tools are needed for basic setup.

Compatibility Notes

The GT2-76N belongs to the Keyence GT2 series. It works with GT2 sensor heads. It also supports optional GT2 communication units. These add communication functions when needed. The unit has no built-in ports or protocols. For network or serial communication, add the correct GT2 communication unit. This modular design helps you upgrade existing GT2 systems.
