GT-A10 Keyence Air Push Sensor Head IP67

Keyence GT-A10 Air Push Sensor Head

Product Introduction

The GT-A10 belongs to the Keyence GT series, a family of general-purpose digital contact sensors. Specifically, this model uses an air push mechanism that extends and retracts the contact element through dry air pressure. Furthermore, its 10 mm measuring range suits automated inspection stations and inline gauging tasks. Meanwhile, the sensor head contains no built-in amplifier, so it depends on a compatible GT series amplifier for power and signal conversion.

Technical Specifications

The GT-A10 sensor head achieves a repeatability of 3 µm at 23 °C with a 100 ms response setting. Additionally, the air push design delivers consistent contact force across different mounting orientations. Downward mounting produces 1.0 N, side mounting yields 0.9 N, and upward mounting results in 0.8 N. These values support stable contact on machined surfaces and castings.

Moreover, the pneumatic section tolerates a pressure resistance of 1.0 MPa. The applied pressure range spans 0.35 to 0.5 MPa, and the working fluid must be dry air. Besides, the 2-meter cable and approximately 135 g body weight keep installation straightforward. For operation, the GT-A10 connects to a GT series amplifier, which supplies excitation and processes the LVDT signal.

Mechanical and Environmental Parameters

The GT-A10 operates reliably in demanding factory conditions. Its ambient temperature rating spans 0 to +55 °C with no freezing permitted. Additionally, the relative humidity tolerance covers 35 to 85 % RH without condensation. Furthermore, the housing carries an IP67 protection rating, so dust and temporary water exposure pose little risk.

First, confirm that the air supply is clean and dry before connection. Next, regulate the pressure within the 0.35 to 0.5 MPa window for consistent actuation. Finally, verify that the mounting orientation matches your required contact force.

Installation Guide

Installing the GT-A10 requires both pneumatic and electrical connections. First, connect the 2-meter cable to the GT series amplifier input according to the amplifier manual. Next, attach the air tube to the push port and set the regulator within the specified range. Then, secure the sensor head using its mounting threads or bracket accessories.

Furthermore, calibrate the amplifier after the air pressure stabilizes. For instance, set the response time to 100 ms to achieve the rated 3 µm repeatability. Besides, keep the contact element and air line free from moisture and debris. In addition, check the air filter regularly to prevent contamination inside the pneumatic chamber.

FAQ

Q1: Does the GT-A10 work without an amplifier?
No. The GT-A10 is a sensor head only. It requires a compatible Keyence GT series amplifier for power supply and signal output.

Q2: What air pressure does the GT-A10 require?
The GT-A10 operates within an applied pressure range of 0.35 to 0.5 MPa. Always use dry air as the working fluid.

Q3: What is the difference between GT-A10 and GT-H22L?
The GT-A10 uses air push actuation with a 10 mm range and IP67 rating. The GT-H22L relies on spring contact with a 22 mm range and lower measuring force.

Q4: How do you ship this item?
We ship via Fedex, UPS, DHL with tracking. Delivery times vary by destination and selected service.

Q5: Is the GT-A10 protected against dust and water?
Yes. The GT-A10 carries an IP67 protection rating, covering dust ingress and temporary immersion.
