m&h infrared probes are touch trigger probes. When approaching a workpiece surface, the stylus deflects and a trigger signal is transmitted to the receiver by infrared light. Interference-free signal transmission between probe and receiver is absolutely vital for process-reliable measuring on machine tools. HDR (High Data Rate) technology avoids interference caused by ambient light from outside and inside the machining area. On the one hand we use the 75 Hz transmission frequency which is different from worldwide line frequencies of 50 Hz or 60 Hz, respectively. On the other hand, an extremely high data rate of 9600 light pulses/sec prevents interference from pulsing machine lamps. Adjustable transmitting power and large transmitting angles go without saying for m&h touch probes. Large receiving angles and microprocessor-controlled evaluation of receiving signals give an absolutely perfect infrared light transmission.
