SANTEST's GYFRS is a probe that improves the vibration-proof and the impact-proof performance. Vibration-proof 10G and impact-proof 200G (2msec) have been achieved. The output signal is compatible with the GYcRS probe, and it is available by combining with GYDC-05 in the digital output and with GYHC, GYFC2 in the analog output for the controller. Moreover, it is possible to combine with digital output (GKS-01) with indicator. The flat head permits a miniaturized application and the flange makes the installation easier, compared with a conventional screw type.
