CABLE CONNECTORS

Apogee sensors offer cable connectors 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 connection to a measurement

device, the unused pigtail lead wire colors are

removed.

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 an installation, 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, one to two

threads may still be visible.

WARNING: Do not tighten the connector by twisting

the black cable, only twist the metal connector.

Inline cable connectors are installed 30 cm from the

sensor head (pyranometer pictured).

A reference notch inside the connector ensures

proper alignment before tightening.

When sending sensors back for recalibration, only send

the section of cable that is hard-wired to the sensor.

The section of cable with the pigtail is not required.

Finger-tighten firmly.
