PRDAT/PRDAWT Series
Long distance inductive proximity sensor (spatter resistance type)
Features

● Long sensing distance (1.5 to 2 times longer sensing
distance guaranteed compared to existing models)
● Coated with the material against thermal
resistance(prevention of malfunction due to spatter)
● Improved the noise resistance with dedicated IC
● Built-in surge protection, reverse polarity protection,
overcurrent protection circuit
● red LED operation indication
● Protection structure IP67(IEC standards)
● Available as spatter-resistance limit switch
Please read “Caution for your safety” 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 teflon against thermal resistance. Also, the protection cover
sold optionally has the same function.

※1: The response frequency is the average value. The standard sensing target is used and the width is set as 2 times of the standard sensing target,
1/2 of the sensing distance for the distance.
※2: The weight with packaging and the weight in parentheses is only unit weight. ※ Environment resistance is rated at no freezing or condensation.
