Tightening Torque; Threaded Sensors - Maximum Screw-In Length; Installation Of Cables - Rechner Sensors IAS Series Instruction Manual

Tightening torque

Threaded sensors are supplied with 2 nuts. 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. For sensors without
thread the range of accessories provides suitable mounting blocks.

Threaded 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. Depending on that the length of the threaded
block for screwing in 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 sensors should be routed separately or screened from heavy conductor lines, as
in extreme cases inductive peak voltages can destroy the sensors despite the integrated pro-
tective circuit. Screened cable or twisted lines are recommended, especially 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 local field power, 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 operated
close to the sensors or additional measures have to be taken in order to eliminate incorrect
operation.
