PRFDAWT30-12DO-IV

PRFDAW Series Full Metal, Cylindrical, Long Sensing Distance, Spatter-Resistance, Cable Connector Type Features Long sensing distance High impact and wear resistance to friction with the work or metallic brush (sensing face/housing material: stainless steel) Reduced possibility of malfunction by aluminum scraps Prevent malfunction due to spatter with PTFE coating Excellent noise immunity with specialized sensor IC Built-in surge protection circuit and output short over current protection circuit Stability indicator (green LED) and operation indicator (red LED) : excellent visibility with the 360˚ ring type indicator (except for PRFDAWT08 model) Equipped with the oil resistant cable Protection structure: IP67 (IEC standard) Please read “Safety Considerations” in the instruction 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. Durability Test Highly resistant to the impact of removing welding sludge attached to the sensing face Continuous hitting test Test conditions Hitting object: 1.3kg of weight Hitting speed: 48 times per 1 min The number of hitting times: 300 thousand times Test model: PRFDAW18 Electromagnetic Resistance Test Metallic brush test Test conditions Testing object: stainless cup brush Rotation speed: 80RPM Testing time: 3 hours Test model: PRFDAW18 Large current from welding generates magnetic field which can affect the proximity sensor to malfunction due to noise. This product, however, can be used near strong noise without malfunctioning, thanks to excellent electromagnetic resistance. This test is conducted in the environment of welding. Test conditions Welding current: 13,000A Installation direction: front and side Test model: PRFDAW Series Diameter of Minimum sensing distance between sensing side weld and sensor Installation direction Front Side 8mm 80mm 80mm 12mm No effect from noise 50mm 18mm 30mm 50mm 30mm 120mm 110mm ※Minimum sensing distance can be different by welding environment.
