* When you connect more than one sensor, you can supply the electric power to any of them. However, the output current is different, depending on which sensor is supplied with the power.
When the power supply is for the center part, control output is 50 mA or less (F70 type: 70 mA or less); stability output is 20 mA or less
When the power supply is for either end, control output is 20 mA or less (F70 type: 40 mA or less); stability output is 20 mA or less
Detection can start when more than 0.5 seconds has passed after power-up. If the load and this sensor use different power sources, be sure to turn on the sensor first.
*1 Please use a connector cable dedicated for input-output connection which is sold separately.
