Permanent current Ia Current flowing during continuous operation. Residual current Ir Current which flows when output is switched off. Residual ripple Alternating current superimposed on direct current. The residual ripple from peak to peak must not exceed the operating voltage limits. Residual voltage Vr Voltage, which is measured via load when the proximity sensor is not actuated. Short-time current Ik Short-time current which flows for a specified period and frequency. Voltage drop Vd Voltage measured between the switch output and the supply voltage (pnp type) or between the switch output and ground (npn type) at maximum current load and when the proximity sensor is actuated. © Festo Didactic GmbH & Co.
