Senses open and closed
valve position in a single-
piece compact housing
Epoxy encapsulated
Available in AC, DC, and
Namur configurations
4-pin Euro connector or
cable versions available
Easily mountable
Compact; approximately
one square inch mounting
footprint
The new NAMCO Valve Position
Proximity Sensor employs a single-piece
design to simplify installation. Two
inductive proximity sensors are in a
single housing. These sensors monitor
target disks on the valve actuator,
sensing up to four disk combinations
which correspond to valve positions. The
sensor is epoxy encapsulated and utilizes
surface mount electronics for reliable
operation under harsh industrial condi-
tions. Three models are available: one
with a standard 10-30 VDC output, one
with 80-250 VAC, and the other a Namur-
style for hazardous location use. 153
