GT2-100N Large Display Amplifier Unit

Product Introduction

The GT2-100N from Keyence is a high-accuracy amplifier unit built for GT2 series digital contact sensor heads. As a panel-mount main unit with a large display and NPN output, it suits control panels where readings must be visible from a distance.

Specifically, this amplifier delivers outstanding precision with a display resolution of 0.1 μm and a display range from -199.999.9 to 199.999.9. Its oversized digits let operators read values at a glance, which reduces eye strain on busy production floors.

Technical Specifications

Measurement Performance

The GT2-100N achieves high measurement accuracy for demanding industrial tasks. Its display resolution of 0.1 μm enables detection of microscopic displacement changes. Meanwhile, the display range spans -199.999.9 to 199.999.9, giving ample headroom for many measurement duties.

Response time is selectable across six levels: hsp(3)/5/10/100/500/1,000 ms. When paired with GT2-Pxxx series sensor heads, the response options shift to hsp(12)/20/40/400/2,000/4,000 ms to match different head characteristics.

Output and Control

This amplifier unit provides control outputs for versatile system integration. The control outputs include HH/HI/GO/LO/LL NPN open collector type, rated for 40 V / 50 mA maximum with residual voltage of 1 V or less.

Furthermore, the comparator output supports five judgement levels, which helps sorting and pass/fail inspection tasks. Each level can be configured independently through the front panel keys.

Input Capabilities

Control inputs on the GT2-100N accept no-voltage signals for timing, preset, reset, and bank functions. Timing input requires a minimum input time of 2 ms, while preset, reset, and bank inputs need 20 ms or more.

Power Requirements

The unit operates on 10 to 30 VDC with 10% ripple (p-p) included, Class 2 rated. Power consumption is 4,500 mW max, which equals 150.0 mA or less at 30 V. This higher draw reflects the larger display, so plan the supply budget accordingly.

Mechanical and Environmental Parameters

Physical Characteristics

The GT2-100N uses a panel-mount body that houses a large-format display. Total weight is approximately 380 g, which is heavier than the standard GT2 amplifier units. The bigger enclosure also needs a larger panel cutout, so check the drawing before installation.

Environmental Resistance

Operating temperature ranges from -10 to +50 °C with no freezing permitted. Relative humidity tolerance is 35 to 85% RH without condensation. Therefore, the unit fits most indoor industrial environments.

Installation Guide

Panel Mounting

The GT2-100N installs into a panel cutout using the supplied mounting hardware. First, cut the panel opening according to the drawing. Next, insert the unit from the front and secure it from behind.

Wiring Connections

The power cable carries supply voltage and control output lines. Brown and blue conductors handle power, while the remaining wires serve the NPN outputs and input signals. Besides, shielded cable is recommended near inverters and servo drives.

Expansion Considerations

The GT2 series supports up to 15 total units, meaning one main unit plus 14 expansion units. When connecting 2 to 8 units, control output current must stay at 20 mA or less. For systems with 9 to 15 units, the current limit drops to 10 mA or less.
