ETA pitch & yaw sensors models BCAV and BCAM measure tilt in 2 directions off the horizontal plane. We are calling these 2 axis B and C. When driving fasteners on angles off-vertical with ETA Smart-Arms, this sensor can be incorporated into the tool holder to provide position feedback on the tool angle. Combined with X and Y position feedback, any errors in location or axial alignment can be eliminated. BC sensors are all solid-state, MEMs devices designed to measure 2 axis tilt (+/- 85° ) in one small rugged sensor, while reporting the data within 0.3 degrees of accuracy in analog outputs of 0.5 – 9.5 V DC (BCAV) or 4 – 20mA (BCAM). The BC sensor features a miniature metal housing and is epoxy encapsulated for vibration, water and dust resistance. It has an environmental rating up to IP 69K. Working temperature range is -40 to 85° C with a maximum temperature drift of +/- 1°. The BC sensor is precisely calibrated to remove non-linearity in the sensing range. It comes with a short cable and a 12mm 4-pin female connector to match ETA analog encoders and Z-axis sensors by using the unassigned pin in those connectors.
