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.
