In stock. Usually ships within 4 to 5 days.
with induction blocking time (the default setting: 2.5S block time): sensor module, after each sensor output (high change Into a low level),you can set up a blockade followed by time period, in this time period the sensor does not accept any sensor signal. This feature can have a "sensor output time" and "blocking time" the interval between the work produced can be applied to detect the interval Products; also inhibit this function during load switching for a variety of interference. (This time the working voltage range: the default voltage DC4.5V-20V micro-power consumption: static current "50 microamps, especially for battery-powered automatic control products the output high level signals: types of circuits can be easily and docking
