PART NUMBER IDENTIFICATION
ELECTRICAL PARAMETERS
Electrical connection DIN 43650 Table A without analog output
DIN 43651 (7 pin), with analog output
Power supply (polarity safe) 18 to 32V DC
Permissible residual ripple 10% (within 18 to 32V)
Current consumption <50 mA (plus load current)
SWITCHING OUTPUT
Switching mode Open collector PNP switched to supply
(suited for inductive load)
Output voltage Supply voltage minus 1.5V (approx)
Analog output O to l0V and 4 to 20mA
Contact rating I
max
= 1A (short-circuit proof)
Switching time < 5ms
Service life 100 million switching cycles
Switching logic Signal “on” with rising pressure, if SP* > RP**
Signal “on” with falling pressure, if SP < RP
* SP = Switching point **RP = Reset point
