Weld Field Immune Inductive Proximity Sensors
E2QW
Square 9-Way Configurable Weld Field
Immune DC 3-Wire & AC/DC 2-Wire
Proximity Sensors Resist Weld Slag
Build-up
• Weld field immunity and noise immunity ideal for automo-
tive welding environments
• Sensing in any of nine directions
• High-temperature abrasion-resistant coating on sensing
face repels weld slag
• Choose Euro, Micro or Mini connector versions
• DC 3-wire PNP-N.O. or AC/DC 2-wire shielded and un-
shielded models
• WFI rated to 20,000 Amps @ 1 inch
