OPTISWITCH 3100 C • Relay (DPDT)
29953-EN-210702
Torque for NPT cable glands and Conduit tubes
Ʋ Plastic housing
max. 10 Nm (7.376 lbf ft)
Ʋ Aluminium/Stainless steel housing
max. 50 Nm (36.88 lbf ft)
Output variable
Output
Relay output (DPDT), 2 floating spdts
Switching voltage
max. 253 V AC/DC
With circuits > 150 V AC/DC, the relay contacts must be
in the same circuit.
Switching current
max. 3 A AC (cos phi > 0,9), 1 A DC
Breaking capacity
Ʋ Min.
50 mW
Ʋ Max.
750 VA AC, 40 W DC (at U < 40 V 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 or AgSnO2 each with 3 µm gold plating
Modes (switchable)
Ʋ A
Max. detection or overflow protection
Ʋ B
Min. detection or dry run protection
Switching delay
Ʋ When immersed
0.5 s
Ʋ When laid bare
1 s
Ambient conditions
