PNP 18mm inductive proximity sensor switch LJ4A3-1
Description:
Promixity switches also calle promixity sensors,sensor can devided into inductive type,capacitive
type,simulative type,hall type,magnetic type.Sensor can support using of PLC programmable
controller,SCM,Sr circuit,Electronic counters,solid-state relay,small relays and other products.
Advantage intruction:
1.Power supply reversal connecton protection;short-circuit protection,can directly connect with PLC
2.Used in common places with medium environment resistance
3.Red LED indicates that it’s available to detect the sensor operating state
4.Economic and simple operation
5.Widely used,can be substitution of min-type switch and limiting switch
6.IP67 Protection structure(IEC specification)
7.Read the “Matters need attention” of the product instruction before using.
