|Output Rating||Voltage sourcing:0-10V dc, 10 mA max.
Current sourcing:4-20 mA, 1 to 500 ohm impedance
|Output Protection Circuitry||Protected against false pulse on power-up and continuous overload or short-circuit of outputs

|Adjustments||The following may be selected by a 4-position DIP switch located on top of the sensor, beneath a transparent o-ring sealed acrylic cover:
Switch 1:output slope positive or output slope negative
Switch 2:current output mode or voltage output mode
Switch 3:loss of echo min/max mode or loss of echo hold mode
Switch 4:loss of echo min/max default output value
|Indicators||5-segment moving dot LED indicates the position of the target within the sensing window
3 LED indicators:Green, Yellow and Red
Green ON steady:power to sensor is ON
Green flashing:current output fault detected (indicates that the 4-20mA current path to ground has been opened)
Yellow ON steady:target is sensed within the window limits (Yellow LED also indicates programming status during setup mode)
Red flashing:indicates relative signal strength of received echo
|Construction||Molded PBT thermoplastic polyester housing, o-ring sealed transparent acrylic top cover, and stainless-steel hardware. Q45U sensors are designed to withstand 1200 psi washdown. The base of cabled models has a 1/2 inch-14NPS internal conduit thread
|Environmental Rating||Leakproof design, rated IEC IP67; NEMA 6P
|Connections||5-conductor 2 m or 9 m shielded PVC-jacketed attached cable, or 5-pin Euro- or Mini-style quick-disconnect fitting. QD cables are ordered separately.
