Early Warning Output
Each shaft encoder is supplied with an early warning output, which
indicates the impending failure of the encoder signals. This warning
is triggered when the LED intensity is about 10% of its original value.
The encoder will still function for more than 1000 hours and the
encoder can therefore be changed at a scheduled maintenance
interval.
Cable
The connecting cable is a flexible 7-pin control cable ( 9-pin with
complementary/inverted outputs) with the following properties :
Core: stranded copper wire
Cross-section: 0.34 mm for power lines
0.14 mm for signal lines
Cable cross section:Circuit G05, G24: 6.3 mm
Circuit I05, I24: 8.3 mm
Shield: Tinned braided copper
Stranded filter wire for simple connection
Outer sheath: light-grey PVC, 0.6 mm
Bending radius:
6 - pin: single bending: min. 31.5 mm
repeated bending: min. 94.5 mm
9 - pin: single bending: min. 41.5 mm
repeated bending: min. 124.5 mm
Line resistance
for 0.14 mm² : max. 148 /km
0.34 mm² : max. 57 km
Operating capacity
Core/Core: 140 nF/km
Core shield: approx. 155 nF/km

Protection from Noise Interference:
We recommend for the effective fault clearance of the
complete system:
For the normal application sufficed putting the
protection of the encoder cable on earth potential, and
taking care that the complete system is grounded low-
impedancely merely (e.g. Braided copper) in a single
place from encoder and output electronics.
In every case the encoder cables seperate protectedly
and locally should be transfered by pieces of
equipment and components producing strength current
lines and disturbances.
Interference sources like engines, solenoid valves are
provided.
In definite applications and in dependence of the
earthing concept and the actually available
interference fields of the complete area it can be
necessary to take up further-reaching fault clearance
measures.
E.g. the capacitive cupling of the shield, the installation
of a HF lock in the encoder cable or the installation of
the transient protective diodes, is part of this.
If these or any other measures are necessary, please
contact us.
