5 Installing
The sensor detects the surface of the medium nearest to the sensor and outputs the distance.
The sensors can be installed in any alignment according to application requirements. The
sound wave is propagated vertically to the sonic transducer at an opening angle of 15°
(LUS211-40…) and 16° (LUS211-130…). The display of the unit can be rotated by 180°
(see parameter DiSr). The maximum tightening torque for fastening the sensor is 40 Nm.

„ When using more than one ultrasonic sensor in an application: Avoid the overlapping of
sonic cones. An overlap can occur if two sensors are mounted less than 200 mm
(LUS211-40…) or 450 mm (LUS211-130…) apart. If this minimum distance is not ensured,
synchronize the sensors via IO-Link.
„ Optional: Rotate the sensor head within the 340° range to align the connection to the I/O
level as well as to ensure optimum operability and readability.
