In early 2011, Pepperl+Fuchs released its first Data Matrix positioning system, the PCV absolute positioning read head. This 2-D camera system uses multi-redundant Data Matrix code tape to provide position data with submillimeter resolution. Along with position, it provides information on the Y-offset (movement up or down) and speed. Since its debut, the PCV has become a sought-after solution for accurate and reliable positioning in a variety of applications.

Industries from automotive to pharmaceuticals share the goal of increasing workflow efficiency on factory floors and in distribution centers. Many are turning to industrial automated guided vehicles (AGVs) to better their intralogistics. With the help of sensor technology from specialists like Pepperl+Fuchs, AGV systems benefit manufacturers in the following ways:

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.

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.

This episode of Ask an Expert for industrial sensors examines and provides answers to interesting sensing questions we've received from customers just like you. We explore and answer these questions:

1. Can the inductive sensor NJ6-F-N operate at -40 °C?
2. How far can a target reflector move sideways before a photoelectric sensor can't read it anymore?
3. Do you have distance sensors compatible with EtherNet/IP and ControlLogix Safety PLC?
4. What sensors could sense plastics and metals through a plastic tray?

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.
