NOTE
• Use this sensor under 80°C.
• Handle these precision parts with special care. In particular, never apply external force to part S.
• The sensor consists of electric circuit. Therefore, keep away from dust, oil, and any other harmful things.
• Mount the sensor, pressing it against the spigot (dimension φA) on the machine (the height of the spigot on the
machine is 4.5 mm or less).
• T The gap between sensor and detecting ring is preadjusted. The output signal may not indicate the target value
due to a dimensional error of the mounting spigot. When installing a sensor, check the output signal. If the
specified value is not satisfied, loosen the screw(*1) and make a gap adjustment.
*1 The recommended tightening torque of the screw is 1.2 Nm (12 kgfcm) (10%. After tightening the screw, check,
with a gap gauge of 0.1 mm, that a gap of at least 0.1 mm is provided between the sensor and the sensor ring.
For the gap adjustment output signal level, refer to "II. INSTRUCTION" in "FANUC AC SPINDLE MOTOR αi
B
series DESCRIPTIONS (B-65292EN)".
• For installation, use screws of M4×20mm and M4×25mm.
• Fasten the cable at a proper location so that if the cable is pulled, no direct force is applied to the sensor.
• Connect the shield wire.
• For easy maintenance, mount the sensor at a position where it can be replaced easily.
• Sensor rings with the same specification number can be replaced with each other.
• Sensor rings with different specification numbers cannot be used in combination.
• Mating connectors are provided with the sensor.
