Steinheil KONTUR 408-2/D Optoelectronic Contour and Shaft Measurement System

High-precision Steinheil KONTUR 408-2/D optoelectronic contour and shaft measurement system with high-quality Jenoptik optics

The system is designed for non-contact, high-precision, and rapid measurement of rotationally symmetric components (e.g., shafts, camshafts, turned parts)

The device scans the measurement object non-contact using the shadow image principle. Rotational measurements are recorded with up to 1,440 measurement points on the circumference per measurement location. Evaluation and quality control are performed directly via integrated SPC (Statistical Process Control) software based on Windows NT, featuring clear tolerance bars and diagrams

The system is housed in a closed aluminum profile enclosure with a transparent protective cover and is safeguarded by professional safety light curtains


System Overview
Operating Principle: It scans workpieces non-contact using the shadow image principle.

Main Application: Fast and precise measurement of complete workpiece contours and shafts in industrial settings.

The Measuring Unit (KONTUR 408):

Vertical measuring setup with integrated IR LED illumination and sensor technology
Measuring range: Diameters from 4 to 85 mm, workpiece lengths up to 400 mm
Drive & scales: Brushless servo motors and high-precision Heidenhain scales
The device is housed in a sturdy aluminum profile frame with transparent protective panels and Sick safety light curtains.
The control& IT Infrastructure:

A rugged 19-inch control cabinet (Rittal) houses the VME bus process computer. A separate PC workstation controls data analysis and visualization (historically designed for Windows NT).
A wide range of standard interfaces on the rear panel (including RJ-45 network, serial COM ports, parallel LPT2 printer port, AUI interfaces, and BNC coaxial connectors)
