Mounting of the Housing ZA
The sensor is mounted with peripheral clamping on the sensor rod, see
figure below.
MICRO-EPSILON recommends to use the mounting set MBS 12/8, which is
available as an accessory. At installation locations where there are no forces and vibrations the sensor can also be mounted by the sensor rod using
radial point clamping with set screws. Plastic set screws must be used so
that the sensor rod is not damaged or deformed.

Installation and Mounting
Centering and Mounting the Plunger
Screw the plunger to the target using the thread. The screw joint must
either be secured with a screw locking compound (e.g. Loctite) or counter-screwed with the locknut supplied. When mounting, please ensure that
the plunger remains freely movable in the sensor and that tilting is avoid.
Observe the measuring tube position at the zero point (= 4 mA output).

Power Supply and Display / Output Device
Power supply and signal output are effected through the 7-pin. connector
at the sensor’s electronic housing. The pin assignment is shown in drawing
and table stated below.
Avoid bending or shortening the plunger.
>> Loss of specified technical data
The minimum bending radius is 30 mm (1.2 “) once, repeated: 90 mm
(3.5 “) for the sensor cable C 703x.

Pin 2 is connected with pin 4 on the sensor electronics. The screen of the
C703 sensor cable is connected with the connector housing.
Connect the screen of the C703 sensor cable with the protective earth
conductor on power side.
The sensors are connected according to the pin assignment, see opposite
table and Figures “Signal monitoring“. Notice the different criteria:
The maximum load resistor RL is limited by the operating voltage UB.

A small load resistor increases the thermal load of the sensor electronics.
With a maximum operating temperature of 85 °C (+185 °F), the minimum

R L can be inserted as an option to adapt the power loss to high
ambient temperatures.
If the signal is monitored with a voltmeter, the load resistor R L is dimensioned in accordance with the desired output voltage U OUT.
Formula: U OUT = R L * I Signal
