With inductive couplers, energy and data are transmitted contactlessly via an air gap. This makes mechanical plug contacts superfluous. If our bidirectional coupling system with IO-Link is used, the data can also be transmitted in both directions. Function=IO-Link, signal form=bidirectional, transmission distance=0...10 mm, component=Base, interface=IO-Link 1.1, connection=plug connector, M12x1 connector, 4-pin, 2.00 m, PUR, rated operating voltage Ue=24 VDC, housing material=nickel-plated brass, dimensions=Ø 28 x 72.8 mm, ambient temperature=-5...55 °C, protection class=IP67, transmission rate=COM2 (38.4 kBaud), additive cycle time=device + 2.0 ms, process data IN=0.32 bytes, process data OUT=0.32 bytes, SIO mode=yes
