Safety Precautions
Refer to Warranty and Limitations of Liability on page F-2.
Precautions for Safe Use
Do not perform wiring work or touch any terminals with power
supplied. Doing so may result in electric shock.
Precautions for Correct Use
Do not use this product in atmospheres or environments that exceed
product ratings.
Sensor Installation
Vibration/
Inclination/
Other Sensors
• Wipe the mounting surface to remove all dirt and use a No. 17
wrench to secure the D7F in place.
Optimum tightening torque: 4.4 to 5.4 N·m
Mounting hole dimensions: M6 holes, Depth: 7 mm min.
• The D7F may not operate correctly if it is not secured with the
proper torque or the mounting surface is not cleaned properly prior
to installation.
• The quick-mounting magnet is provided to help locate the proper
detection position. Make sure the D7F is secured with screws for
long-term applications.
• The quick-mounting magnet will not hold the D7F if the magnet is
installed vertically or backwards.
Quick-mounting Magnet Dimensions
Handling the Sensor
• The Sensor Cable can be cut to any length, but it cannot be
extended.
• Do not disassemble the D7F. Otherwise, it may not operate
properly.
• Make sure all wiring is correct and be careful not to short wires
while wiring.
• Do not install the D7F in locations subject to oil. Otherwise, the
rubber seal will deteriorate, allowing liquids such as oil or water to
enter the D7F, which may cause it to fail.
• The D7F should be connected only to a specified Controller, such
as the D7F-C01 or D7F-C03.
Handling the Controller
• The Controller should be connected only to a specified Sensor,
such as the D7F-S01-@@ or D7F-S03-@@.
• Do not attempt to disassemble the Controller. Otherwise, it may not
operate properly.
• Do not install the Controller in a dusty location or one subject to
water or oil.
• Do not mount the Controller directly to any source of vibration.
