Detector
The 65-2300RK-SO2 detector consists of the detector housing body, detector housing cap,
splashguard, cap gasket, and the plug-in sensor.

Toxic Detector Component Location
Detector Housing Body
The detector housing body protects the electronic components within the housing. Use the
mounting threads at the top of the housing to screw the toxic detector into a 3/4” NPT
hub. Two wires extend from the top of the detector housing body. Use these wires to
connect the toxic detector to a controller. One of the wires is black and one of the wires is
blue.
The housing body includes a 12 position connector at the bottom of the housing body. The
plug-in sensor mates to this connector. A pre-amplifier located between the connector and
the two interconnect wires conditions the sensor’s signal before the signal reaches the
controller.
Housing Cap, Cap Gasket, & Splashguard
The housing cap screws onto the detector housing. It retains the sensor and protects it
from damage. A removable splashguard is screwed onto the detector cap to protect the
sensor from impact damage, direct water spray, and splashing. Unscrew the detector cap
to access the sensor for maintenance or replacement. A cap gasket seals the interface
between the housing and cap.
Plug-in Sensor
The plug-in sensor is secured in the detector assembly by the housing cap. Through a
series of chemical and electrical reactions, the sensor produces an electrical output that
corresponds to the detection range of the sensor.
Conduit Seal
The conduit seal isolates the volumes of the 2 junction boxes.
