Technical data
2.5 Sensor data for non-ferrous (NF) material
The amount of eddy current generated and the corresponding energy absorption is directly related
to the electrical conductivity. High values of electrical conductivity and the corresponding strong
eddy currents reduce the controllable sheet thickness.
The eddy current principle is more forgiving with regard to air gaps than the electromagnetic
principle.However, for most reliable performance precaution should be taken to avoid air gaps
between sensor and sheet. The permissible air gaps between first and second sheet can be slightly
higher than for steel.

Sensor cables

Suitable cable type:
• Superflex (C)Y PURKOMBI 2 x 1,0 mm² + 4 x 2 x 0,25 mm²
• The cable is oil-proof and suitable for drag chains
- Bending radius flexible use min. 110 mm
Cable marking:
• for PW42AGS:
SCPWS-GG (straight receptacle at the sensor)
SCPWS-GW (right angle receptacle at the sensor)
The cable have quick disconnects at both ends. The plug at the control unit side is always straight.

Note The system reaction time for non-ferrous materials is constant at 85 ms.
This applies for measurements with 1 sensor as well as for measurements
with 2 sensors (in sequencer mode).

Note The sensor cable is an active component of the sensor technology. The
technical data of the sensors is valid only if the cable specification is met. A
shielded cable (2 x 1,0 mm² + 4 x 2 x 0,25 mm²) must be used. The cable
length can be to up to 50 m. Following the rule "the shorter the better"
generally leads to better measuring results.
