V2 XGuard RC Back Plate Self Calibrating RPM Sensor with AGC (FUTABA)

Note: Now Compatible with OS-105, OS-91, YS-120, YS-96, YS-91, YS-60, OS-55 and OS-50.

The XGuard Self-Calibrating V2 Back Plate RPM Sensor with Static discharge protection and sensor power buffering is the most advanced Back Plate RPM Sensor to date.

This sensor instead of having a fixed trigger point that might work or not with your particular engine, it works by sensing the magnetic field variation of the first pulses and calibrates itself to the ideal magnetic field trigger point for that particular engine.

It measures the max and min magnetic field via an amplified hall-effect sensor and calculates the ideal trigger point for that particular range your engine presents to the sensor. This effectively self-calibrates the sensor to work optimally in your engine.

Because of this feature it even works on YS engines with their steel plates. Watch the video and you’ll see it working on a YS210 back plate. Not only that but it also works with side-installed configurations and senses the crankshaft counterweight passing but the side of the crankcase. Check the video to watch that in action.

Please pay attention to the correct positioning of the sensor below:
