4.0 - Connections (Operation)
Bray offers three different connections to satisfy the customer’s
application requirements. Each sensor’s pin connection is
listed in its respective technical manual. Turn off all power and
lockout/tag out service panel before installing or modifying
any electrical wiring.
4.3 - Sensor
and Solenoid
(Independent)
Bray also offers sensors
with dedicated solenoid
outputs. In this set up the
sensor signal and solenoid
power are transmitted on
the main system side line.
The solenoid is activated
via power supplied from
the sensor through the
S-connector. S-connector
selection can be found
in the sensor technical
manual.
4.2 - Sensor and
Solenoid (Shared)
Y-connectors are used to
allow solenoid control on
sensors without dedicated
solenoid outputs. The
system side line carries
both the sensor and
solenoid power. The
system side line splits to
supply power and signal
to sensor and solenoid.
4.1 - Sensor Only
Sensor connection sup-
plies sensor power and
signal output.

4.4 - Cable Gland Connections
M20 cable gland connections are found on the following
sensors:
540032-71104533
540013-71104533
540015-71104533
540102-71104533 (
included in Kit PN 540102-126xx536)
In order to field-wire these models, follow these guidelines.
1. Take the sensor cover off. The cover should be kept on
hand for reference.
2. Wire the sensor as per the wiring diagram on the outside
of the sensor cover or technical specification sheet.
3. Close the cover and securely tighten cover screws
Range of wire size gauge acceptable
(single conductor per terminal)
General: 16 to 28AWG
Industrial: 14 to 22AWG
Hazardous: 14 to 22AWG
NOTICE
Cable glands used must be certified in accordance
with the application. The temperature range of cable
glands must be selected according to application. The
degree of ingress protection must not be reduced by
cable glands.
The cable gland connections must be properly sealed
to maintain the Ingress Protection rating of the S54
sensor. Use a seal that meet the requirements of the
application.
If the sensor is mounted on a vertical pipe, it is
recommended that the sensor be positioned with the
cable glands on the bottom to prevent condensation
from entering the sensor through its conduits.
In all cases, the conduit should be positioned to prevent
drainage into the sensor
Ensure adequate drainage of wiring conduit to prevent
water contamination inside sensor
