Unformatted text preview: re technology Series connection of proximity sensors using three-wire technology is possible, as shown in Fig. 10.3.4, whereby the following points must be observed: • The outputs of the individual series connected proximity sensors are loaded additionally: Added to the current consumed by the load is the current consumption of each individual proximity sensor connected in series. • In the switched through status, a voltage drop occurs with each proximity sensor (approximately 0.7 – 2.5 V per sensor). As a result of this, the supply voltage available for the load is reduced by the sum total of the individual voltage drops. • As in the case of series connected three-wire sensors, it is always the supply voltage of the proximity sensor connected downstream which is switched, the actual time delay before availability must be taken into account. If a "detection process" falls within the period of the time delay before availability, this can lead to malfunction. In the case of proximity sensors with operating status display (LED,...), correct indication of the oper...
