m&h Infrared Receiver IRR91.40


m&h IRR91.40 - with HDR technology, mounted directly in the headstock

The Infrared Receiver IRR 91.40 reliably transmits and receives measurement and temperature data. It can communicate with all m&h Infrared Probes, the Pick Up Tool Setter IRPT35.40 and Infrared Tool Setter IRT35.70. The receiver can communicate with two different probe systems on the same machine. All necessary components are integrated in the stainless steel housing, thus no additional interface is required in the electrical cabinet. It can be mounted without creating any obstructions in the machining area or directly in the headstock.
