Dwyer DT - Manual

Series DT Detector position sensors consist of two basic components,
a hermetically sealed reed switch sensor assembly and a magnetic
actuator assembly. A change in state of the contacts in the sensor is
initiated by moving the actuator closer to or further away from the sensor
target area, either into or away from the reed switch magnetic sensing
range. This opens or closes the electrical circuit.
SENSORS
Detector sensors are 316 SS bolts with 5/8˝-18 UNF external threads
and a 1/2˝-14 NPT conduit entrance. The durable SPDT reed switch is
potted inside the sensor enclosure.
ACTUATORS
The actuator is a 316 SS bolt with a magnet embedded in the head. The
available actuators provide levels of sensitivity for either 0.1˝ or 0.5˝
sensing capability.
MECHANICAL INSTALLATIONS
1. The sensor(s) and actuator may be mounted in any position. Choose
orientation that best fits your needs.
2. Install sensors individually, side-by-side, facing the same direction, at
90° or facing each other at a minimum of 3˝ apart.
3. Determine desired operating point. Use actuator supplied with sensor,
keeping all magnetic materials away from the sensor assembly.
4. Locate sensor and actuator mounting assemblies to assure the
actuator will move within the switch sensing area.
5. Adjust setpoints by rotating either the sensor or actuator or both in
their respective threaded bracket assemblies. This will move them closer
together or farther apart for desired operation.

ELECTRICAL CONNECTIONS
Use a 18 AWG, 4-conductor, shielded cable or 1/2˝ NPT conduit
connectors. For correct wiring refer to the wiring diagram (Ground:
Green, NC: Red, NO: Black and Common: White). Long runs of cable or
conduit should be supported at the sensor to avoid pulling it out of
position. For installation in hazardous locations, check local electrical
codes. The Detector position sensors are designed to NEMA 4, 4X, 7 ,
9.
