IP66 & Type 4X housing – Withstands hose-directed water, dust, and corrosive environments.
FAQ
Q1: What is the total standoff plus penetration length for this model?
A1: B (1.5”) + C (2.7”) = 4.2 inches (107 mm), which requires no additional sleeve support.
Q2: Can I use this PROXPAC XL without any conduit fittings?
A2: Yes, DD=00 supplies two plugs and washers to seal unused ports, perfect for flexible conduit or sealed wiring.
Q3: What is the recommended gap setting for this 8mm probe system?
A3: The recommended gap is 1.27 mm (50 mils), giving an output of approximately –10 Vdc.
Q4: Does this assembly require an extension cable between probe and Proximitor?
A4: No, the probe connects directly inside the housing to the built-in Proximitor sensor, eliminating extension cables.
Q5: What hazardous area approvals does AA=28 provide?
A5: Multiple approvals include cNRTLus (Class I, Zone 0/2, Div 1/2) and ATEX/IECEx (ia IIC, nA/ec IIC).
