Tightening Torque; Installation Of Cables - Rechner Sensors 80 Série Notice D'utilisation

Tightening torque

In order to prevent damage to the threaded sleeves when mounting, the material and version-dependent
maximum torque should be taken into consideration. The values listed in the table are based on the
use of the nuts supplied with the sensors.

Maximum screw-in length
Due to the permitted thread tolerances specified in German standard DIN 13, the maximum screw-in
length for threaded sensors should be taken into consideration. on the length of the threaded block in to
which it is screwed, proximity sensors should not exceed the following dimensions. In the case of larger
threaded blocks we recommend drilling a blind hole in order to adhere to the maximum screw-in length.

Installation of cables

Wiring of the sensor should be routed separately or screened from heavy conductor
lines, as in extreme cases inductive peak voltages can destroy the sensors despite the
integrated protective circuit. Screened cable or twisted lines are recommended, espe-
cially for longer cable runs > 5 m. Direct control of electric light bulbs is to be avoided,
because during the switch-on moment cold current is many times the rated current and
can destroy the output stage of the sensor
Units with strong fields near by, e. g. high power walkie-talkies, or noise sources in the
lower frequency range, e. g. long, middle or short wave transmitters should not be oper-
ated close to the sensors or additional measures have to be taken in order to eliminate
incorrect operation.
