The DMH series are high-speed optical data transmission devices that enable parallel I/O data to be transmitted quickly and reliably over short distances.  Typical applications include automated guided vehicles (AGV), rail-guided vehicles (RGV), overhead hoist transfer (OHT) systems and skillet conveyors where a wireless link is provided between the vehicle and a fixed docking station.  Through FSK modulation, these transceivers can send 16-bit signals from active to passive sides within 15ms or less.
