PRAWT12-2DC

PRAW Series Cylindrial, Spatter-Resistance, Cable Connector Type Features ● Prevent malfunction due to welding spatter with PTFE coating ● Improved the noise immunity with dedicated IC ● Built-in surge protection circuit ● Built-in output short over current protection circuit ● IP67 protection structure (IEC standard) ● Replaceable for spatter-resistance type limit switches Please read “Safety Considerations” in operation manual before using. The Characteristic of Spatter-Resistance Type The hot arc from arc welding machine is adhesive even with metals or plastics. Therefore, normal proximity sensor might have malfunction even though there are no sensing object if the arcs are put on the sensing surface. The arcs are not adhered on the sensing part of the spatter-resistance type proximity sensor as the part is coated with PTFE against thermal resistance. Also, the protection cover sold optionally has the same function. Specifications ※When the ● DC 2-wire type model name is X, it is non-polarity model.

The load can be connected to either wire. In case of the load current is small If the load current is under 5mA, please make sure the residual voltage is less than the return voltage of the load by connecting a bleeder resistor in parallel with the load as shown in the diagram. ● DC 2-wire type Brown Vs Vs2 (kΩ) P> (W) I R [I: Action current of load, R: Bleeder resistance, P: Permissible power] R≤ Load Bleeder resistor (R) Blue + - Vs Please make the current on proximity sensor smaller than the return current of load by connecting a bleeder resistor in parallel. ※W value of Bleeder resistor should be bigger for proper heat.
