SKF - Lincoln ultrasonic sensor

• Non-contact ultrasonic distance measurement (range 65–600 mm, blind zone 0–65 mm)
• Ultrasonic frequency approx. 400 kHz, internal temperature compensation
• 3 switch points: high-level, low-level and programmable pre-low-level
• Operating voltage 9–30 V DC, reverse-polarity protected
• 3 × PNP output (NO), short-circuit proof, Imax 3 × 200 mA
• Connection 5-pole M12 plug
• Protection class IP 67, operating temperature -40…+70 °C
• Mounting into reservoir lid (bore Ø 20 mm), tightening torque 1.5 Nm

Switch points (factory setting, model 664-85324-4 / BU):

• LS (sensor operating length) = 790 mm
• VS (pre-low-level) = 365 mm
• VLO (low-level) = 740 mm

The switch points are factory-set according to the reservoir height. The physical sensor (housing, ultrasonic transducer, M12 connection) is identical across all BU variants – only the switch points (LS / VS / VLO) differ by reservoir size. Please verify your reservoir dimensions when ordering.
