CTS2 Contact Displacement Sensor – When Contact Measurement Is the Better Choice

Non-contact measurement is not always the best choice. When a workpiece provides a stable mechanical reference and the application requires repeatable dimensional, thickness, offset, flatness, or position measurement, contact measurement can offer a practical solution. The Huayifeng CTS2 Series uses CMOS grating measurement and optical absolute-value principles, with resolution options down to 0.2μm and a 12.7mm measurement range for precision industrial applications.

Huayifeng develops industrial sensing and measurement products for automation equipment, automotive, electronics, semiconductor, robotics, and precision manufacturing applications. CTS2 expands this portfolio with a contact-based measurement option for projects where direct probe measurement is appropriate.

When Should You Use Contact Measurement Instead of Non-Contact Measurement?

Contact displacement measurement is useful when the application allows the probe to touch the workpiece and requires a clear mechanical reference. It can be a practical choice for dimensional inspection, eccentricity, thickness, flatness, or stage-position verification. By contrast, non-contact sensors are normally preferred when the target cannot be touched, the surface is soft or easily damaged, or high-speed measurement without mechanical contact is required.

The CTS2 Series is designed for industrial applications that require:

  • High-resolution displacement measurement
  • Stable static and dynamic detection
  • Accurate dimensional inspection
  • Easy integration into automation equipment
  • Reliable communication through RS485 interface

Typical industries include automotive manufacturing, electrical and electronic production, semiconductor equipment, robotics, precision machinery, and new energy applications.

Why CTS2 Works for Precision Contact Measurement

The CTS2 Series combines absolute grating measurement, CMOS optical reading, industrial communication, and spring-type or pneumatic-type drive options to support different measurement setups.

Up to 0.2μm Resolution – Not 0.2μm Accuracy

The CTS2 Series provides resolution options down to 0.2μm, meaning the sensor can resolve very small displacement changes. Resolution should not be confused with full-range accuracy: accuracy varies by model and should be checked against the selected specification before publishing or quoting a precision claim.

Typical applications include:

  • Motor shaft eccentricity measurement
  • Automotive part dimensional inspection
  • X-Y stage position verification
  • Thickness and flatness detection
  • Precision component quality control

Spring-Type and Pneumatic-Type Models

To meet different application requirements, CTS2 provides two detection methods:

Feature Spring-Type CTS2 Pneumatic-Type CTS2
Measurement Range 0–12.7mm 0–12.7mm
Resolution 5μm to 0.2μm 5μm to 0.2μm
Detection Method Mechanical spring force Air-driven measurement
Measuring Force 1.1–1.2N 2.4–3.4N
Application General precision inspection Automated production systems

The spring-type model is suitable for standard measurement applications, while pneumatic models are ideal for automated lines requiring controlled measurement force.

Technical Specifications of CTS2 Series

The CTS2 Contact Displacement Sensor provides flexible integration options for industrial automation systems.

Key specifications include:

  • Measurement range: 12.7mm
  • Resolution: 0.2μm / 0.5μm / 1μm / 5μm options
  • Accuracy: ≤1.4μm depending on model
  • Response time: 50ms
  • Communication protocol: Modbus RTU via RS485
  • Power supply: 5–24VDC
  • Operating temperature: -10°C to +50°C
  • Protection rating: IP65
  • Housing material: Aluminum alloy

These specifications make CTS2 suitable for precision measurement applications, but final resolution, full-range accuracy, measuring force, and drive method must be confirmed according to the selected model.

How CTS2 Integrates Into an Automation System

CTS2 uses absolute grating technology with CMOS optical measurement to convert probe displacement into digital measurement data. RS485 communication with Modbus RTU enables integration with industrial controllers and automation equipment.

The typical measurement process includes:

  1. Install the CTS2 sensor on the measurement equipment.
  2. Select the suitable probe type according to the application.
  3. Connect the RS485 communication interface with the control system.
  4. Calibrate the sensor according to measurement requirements.
  5. Collect and analyze displacement data during production.

This workflow helps manufacturers improve inspection efficiency and reduce manual measurement errors.
