CABLE CONNECTORS

Apogee started offering cable connectors on some

bare-lead sensors in March 2018 to simplify the

process of removing sensors from weather stations

for calibration (the entire cable does not have to be

removed from the station and shipped with the

sensor).

The ruggedized M8 connectors are rated IP68,

made of corrosion-resistant marine-grade stainless-

steel, and designed for extended use in harsh

environmental conditions.

Instructions

Pins and Wiring Colors: All Apogee connectors

have six pins, but not all pins are used for every

sensor. There may also be unused wire colors

inside the cable. To simplify datalogger

connection, we remove the unused pigtail lead

colors at the datalogger end of the cable.

If a replacement cable is required, please contact

Apogee directly to ensure ordering the proper

pigtail configuration.

Alignment: When reconnecting a sensor, arrows

on the connector jacket and an aligning notch

ensure proper orientation.

Disconnection for extended periods: When

disconnecting the sensor for an extended period

of time from a station, protect the remaining half

of the connector still on the station from water

and dirt with electrical tape or other method.

Tightening: Connectors are designed to be firmly

finger-tightened only. There is an o-ring inside the

connector that can be overly compressed if a

wrench is used. Pay attention to thread alignment

to avoid cross-threading. When fully tightened, 1-2

threads may still be visible.

WARNING: Do not tighten the connector by

twisting the black cable or sensor head, only twist

the metal connector (yellow arrows).

Cable connectors are attached directly to the head.

A reference notch inside the connector ensures

proper alignment before tightening.

When sending sensors in for calibration, only send the

sensor head.
