Cable Connectors

Apogee started offering in-line cable connectors on some

bare-lead sensors in March 2018 to simplify the process of

removing sensors from weather stations for calibration by

not requiring the full cable to be uninstalled back to the data

logger.

The ruggedized M8 connectors are rated IP67, made of

corrosion-resistant marine-grade stainless-steel, and

designed for extended use in harsh environmental

conditions.

Inline cable connectors are installed 30 cm from the head

(pyranometer pictured)

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 data

logger connection, we remove the unused pigtail lead colors

at the data logger end of the cable.

If you ever need a replacement cable, please contact us

directly to ensure ordering the proper pigtail configuration.

Alignment: When reconnecting your sensor, arrows on the

connector jacket and an aligning notch ensure proper

proper alignment before tightening.

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.

When sending sensors in for calibration, only send the short

end of the cable and half the connector.

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.
