Power supply:
Please use a power supply unit with an output voltage of 8 – 36 VDC/ 100 mA.
Cable connection:
The cable gland M12x1,5 allows the use of cables with a diameter of 3 to 5 mm.
To prevent electrical and electromagnetic faults and variance of measuring values keep to the following
precautions:
Please install the measuring head and the electronic box in a distance as far as possible from any source,
which may cause electromagnetic interference (e.g. modules with electromotor-impulse).
If necessary, mount the head insulated to prevent ground loops.
CAUTION: Use shielded cables only. The sensor shield has to be grounded.
Preparation of the cable:
Remove the isolation from the cable (40 mm power supply, 50 mm signal outputs, 60 mm functional inputs).
Cut the shield down to approximately 5 mm and spread the strands out. Extract about 4 mm of the wire
isolation and tin the wire ends.
Installation of the cable:
Place the following components one after the other onto the prepared cable end:
The cap, the clamp ring, the rubber washer and one metal washer of the cable gland. Spread the strands and
fix the shield with the second metal washer. Insert the cable into the cable gland until the limit stop. Screw the
cap tight. Every single wire may be connected to the according screw clamps according to their colors.
Sensing head/ -head cable:
The standard delivery includes the connected cable of the sensing head to the electronic box. You may
shorten but never lengthen the cable. To shorten the cable may cause additional measuring errors of about
0,1 K/ m.
The head is exchangeable.
