(With being supplied to each of the sensors. For this reason, series 12Vdc relays, switching is not possible.) connection of proximity sensors is not recommended. However, if proximity sensors must be connected in series, a Operation at power ON  resistor of 10k must be provided in parallel to each of the After the power is turned ON, it takes 40ms or less until the sensors. However, note that the maximum leakage current in proximity sensor is ready for sensing. a series connection will be 3.5mA. When the load and the proximity sensor use different power Operation lag also will occur, resulting in increased voltage supplies, be sure to turn the proximity sensor ON before turning drop, and the operation indicator lamp will not light. the load ON. Operation lag = 40ms (number of series connections ~ 1) Voltage drop = voltage drop of single sensor number of Influence of leakage current  series connected sensors Minimal current flows as leakage current for operating the cir- cuits even when the proximity sensor is OFF. Take sufficient care when restoring connected loads. Minimum cord bending radius (R)  The minimum bending radius (R) of the cord is 3 times cord di- ameter, take care not to excessively bend the cord beyond this (2) Parallel connection (OR connection) radius. Also, do not excessively bend the cord within 30mm of • When connecting two or more proximity sensors in parallel, the cord lead-in port. leakage current increases as follows, and may result in faulty load restore. (Leakage current = Leakage current of single sensor number of series connected sensors) • When two or more sensors turn ON in a parallel connection, one (or some) of the sensors may not indicate operation. This is not an abnormality. RESTRICIONS ON USE This product has been designed, developed and manufactured for general-purpose application in machinery and equipment.
