Inductive Distance Sensor

Installation and connection
5.1
Installation
For dimensions, see Fig. 4-1 on page 7.
NOTICE
Interference in function
Improper installation can compromise the function of the
sensor and result in damage.
► Ensure that no strong electrical or magnetic fields are
present in the direct vicinity of the sensor.
Any orientation is permitted.
► Install sensor flush (tightening torque: 25 Nm).
Fastenings (mounting clamps, brackets,
clamping frames, mounting brackets) are
available as accessories at www.balluff.com.

Shielding and cable routing
Defined ground!
The sensor and the control cabinet must be on
the same ground potential.
Magnetic fields
The sensor operates according to the eddy current
principle. Be sure to provide sufficient distance of the
sensor from strong external magnetic fields.
Cable routing
Do not route the cable between the sensor, controller, and
power supply near high voltage cables (inductive stray
noise is possible).
Inductive stray noise from AC harmonics (e.g. from phase
angle controls) are especially critical and the cable shield
offers very little protection against this.
Cable length
Cable length max. 20 m. Longer cables may be used if
their construction, shielding and routing prevent noise
interference.
