The MGS1600C magnetic guide sensor from Roboteq Inc., Scottsdale, AZ, can detect and report the position of a magnetic field along its horizontal axis. Intended for line-following robotic applications, the 165 mm wide sensor measures its lateral distance from the magnetic tape track guide on the floor with position resolution of 1 mm. Primarily used to steer automatic guided vehicles (AGVs), the sensor has RS-232, USB, CANbus, analog, or PWM ports; can be interfaced to any of the company's motor controllers; and can be connected to any PLC. It can detect and manage up to 2-way forks and can be instructed to follow the left or right track using commands issued via its digital inputs.
