How to Assemble a Linear Encoder Shield Housing for PosiTrack System

Posted by Gerry Paci on Fri, Sep 29, 2017

The PosiTrack Shield is an accessory upgrade for our PosiTrack absolute position linear encoder. You can use the PosiTrack read head for absolute positioning of conveyor vehicles, vertical lifts, or indoor cranes. By adding the PosiTrack Shield, applications in harsh outdoor environments like offshore installations (ships, ports, harbors) or outdoor cranes are no problem.

The Shield's IP69 rating also serves to shelter the read head in high-pressure washdown areas. With integrated heating, temperatures as low as -40 °C keep the read head operating efficiently. The Shield is also downward compatible with current PosiTrack installations.

Position Guided Vision for Automatic Guided Vehicle (AGV) Control

Posted by Gerry Paci on Fri, Mar 10, 2017

Automated guided vehicles (AGVs) are used to move product throughout the factory or warehouse floor. Speed and precision are key when moving materials— if you've seen AGVs zipping around in a warehouse, you want to ensure that they stay on track and that they go exactly where they need to, with materials and AGV intact.

The video below discusses the key features and general applications for our PGV absolute positioning system for automatic guided vehicles. The PGV follows Data Matrix codes or colored lines with sub-millimeter precision and is ideal for guidance of AGVs.

From control codes to initiate starts, stops, and turns, to the user-friendly software Vision Configurator, the PGV is packed with the tools you need for any AGV application.

Anti-Swing Software and Inductive Sensors Raise Your Mobile Equipment to a Higher Level

Posted by Patricia Stafford on Thu, Jul 07, 2016

Controlling the motion of cranes, hoists, and other mobile equipment while avoiding accidents is a vital part of ensuring their safe and efficient operation. Vertical lift applications can be trickier and pose greater risks than working with horizontal conveyor belts, which tend to be more steady and predictable.

Selecting the Components of a PCV Data Matrix Positioning System

Posted by Tracy Molnar on Tue, May 21, 2013

What is PCV?

PCV is an absolute linear positioning system.  A continuous band of Data Matrix codes is installed along the application’s travel path. A camera-based read head, typically mounted on the moving part, reads these codes.  Depending on the type of read head, position data is transmitted to the control system using RS485, SSI, or PROFIBUS DP communication.
