Power and data cable assembly for the TriSonica Mini LI-550P — 12-position circular plug, solder-terminated, 28 AWG. Carries both the sensor's 5–32 VDC supply and its serial data on a single run.

Fits the LI-550P only. The pole-mount LI-550P is the model with the 12-pin circular connector. The flat-base LI-550F terminates in four bare wires and does not accept these cables — if you have an F, wire it directly to your logger or power supply instead.

Which length?

• 5 m — sensor at the top of a short mast or tripod with the logger enclosure at its base.
• 10 m — taller masts, or a logger enclosure set away from the mast at ground level.

Measuring tip: run the tape from the sensor head down the full mast to where the cable actually enters your enclosure, then add slack for a drip loop and strain relief. Coming up short on a mast is a return trip.

Connecting to a telemetry gateway? See telemetry & remote monitoring — the sensor's RS-232 output reads directly into a serial logger input.
