Output variable
Output
Relay output (2 x SPDT), 2 floating spdts
Switching voltage
Ʋ Min. 10 mV
Ʋ Max. 253 V AC, 253 V DC
Switching current
Ʋ Min. 10 µA
Ʋ Max. 5 A AC, 1 A DC

If inductive loads or stronger currents are switched
through, the gold plating on the relay contact surface will
be permanently damaged. The contact is then no longer
suitable for switching low-level signal circuits.
Contact material (relay contacts) AgNi (Au plated) or AgSnO (Au plated)
Modes (switchable)
Ʋ Max. Max. detection or overflow/overfill protection
Ʋ Min. Min. detection or dry run protection
Accuracy (according to DIN EN 60770-1)
Reference conditions and actuating variables according to DIN EN 61298-1

Ʋ Product temperature +18 … +30 °C (+64 … +86 °F)
Ʋ Product density 1 g/cm³ (0.036 lbs/in³) (water)
Ʋ Product viscosity 1 mPa s
Ʋ Superimposed pressure 0 kPa
Ʋ Sensor installation Vertically from top
Ʋ Density selection switch > 0.7 g/cm³
