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.
• The dimensions marked with asterisk are applied to the fitting diameter. Be sure to install the sensor so that it is
aligned with the inner or outer diameter of the guide. Otherwise, the detector may produce incorrect output.
• 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)".
• 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.
