SND8S

Product catalog summary

Overview
The document describes the SND8-NS11 Weld Seam Detection system, designed for detecting weld seams in tin plate containers such as cans, pails, and drums. It operates using a magnetic principle, making it independent of surface decorations.

Specifications

Detects weld seams in ferrous materials with wall thicknesses up to 1.0 mm.
Operates with a minimum peripheral speed of 0.1 m/s, with no upper speed limit.
Relay output with a switching voltage of 250 V max and current of 8 A max.
Operating voltage: 230/115V AC, 50-60 Hz.
Ambient temperature range: 5° - 45° C.

Functionality
The system uses the NS11 sensor to detect magnetic field deformations caused by weld seams. The sensor is housed in a robust aluminum casing and requires a fixed distance from the container for accurate detection. The control unit processes the sensor data and provides a switch signal for machine controls.

Installation and Adjustment

Connect the control unit to the appropriate operating voltage.
Install the sensor with a specific fixture to maintain a 1-5 mm gap from the container.
Adjust the switching threshold by rotating the container and adjusting the sensitivity potentiometer until the signal LED lights up periodically.

Applications

Expanding machines for square cans.
Welding of ears for handle attachment.
Screen printing on drums.

Technical Data

Power consumption: approx. 25 VA.
Relay on delay: 110 ms, ±20%.
Relay outputs for weld seam and fault detection.

Order Information

During the production of various types of tin plate containers it can be necessary to detect and position the weld or lock seam. The Weld Seam Detector SND8 - NS11 was specifically developed for this purpose. It reacts to themagnetic properties of the weld seam and functions therefore completely independent of the lithographic decorations on the metal surface. Weld seams result in characteristic deformations of the magnetic field. These changes are captured by the NS11sensor, analyzed in the control unit, and processed resulting in a switch signal available for the machine controls. The sensor...
