The Simplest and Most Reliable Guiding Technique for AGVs
Roboteq’s Magnetic Guide Sensor is capable of detecting and reporting the position of a magnetic field along its horizontal axis. Our sensor is intended for applications in Automatic Guided Vehicles (AGVs), using inexpensive adhesive magnetic tape to form a guide on the floor.
Build an AGV with Only Two Components

A complete, Magnetic Guide following AGV can be built with just an MGS1600 sensor and one of the many dual channel motor controllers in our catalog.
We have prepared an Application Article, complete with descriptions, drawings and programming code to show you just how simple it is.

Superior to Other Guiding Techniques
Technique | Easy to lay | Easy to change | Passive | Dirt immune | Ιnvisible |
---|---|---|---|---|---|
Magnetic Guide | Yes | Yes | Yes | Yes | Yes |
Induction Wire | No | No | No | Yes | Yes |
Optical | Yes | Yes | Yes | No | No |
Compared to other guiding techniques, magnetic guides are totally passive and therefore easy to lay and modify. The tape creates an invisible field that is immune to dirt and unaffected by lighting conditions. The magnetic track can be totally hidden under any non-ferrous flooring material.
Precise, Sensitive, Fast

Effective Forks and Location Markers Management

Easy to Interface with Anything
The MGS can be interfaced directly with any of Roboteq’s motor controllers in order to create an effective AGV solution with just two components. The sensor can also be connected to any PLC, PC or single board computer using a choice of Analog, PWM, RS232, USB or CANbus interfaces.

Tough and Tougher


Chose between ABS plastic with 2m cable, or all-metal with a waterproof industrial M12 connector.
Built to last, both are equally IP64 water and dust resistants
See the Invisible, Run Virtually
The shape of the track's and marker's magnetic field under the sensor can be visualized in real-time in Roboteq's free PC utility. This unique capability takes the guessing out of troubleshooting.

Flexible and Durable Magnetic Tape
Tape is available in 25 and 50mm width. The wider tape offers a larger adhesive area and is very well suited for use in heavy traffic areas. The tape is easy to lay and can be bent to create virtualy any shape paths.
For heavily traveled areas Roboteq offers a 5x5mm square tape that can be inserted in a groove carved into the floor.
