Autonics PRAW Series Catalog Page
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.

Weight
※
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: Before using non-polarity type, check the condition of connected divice because residual voltage is 5V.
※
3: The weight includes packaging. The weight in parenthesis in for unit only.
