C7772A-E
Wallplate Temperature Sensor
FEATURES
• Low profile when mounted on industry standard utility
conduit box.
• Rugged, brushed stainless steel wallplate.
• Integral foam pad isolates wallplate sensor from
conduit box.
• Insulated screw terminals ensure reliable field wiring
connection.
• Models available with a variety of resistive temperature

PRODUCT DATA
APPLICATION
The C7772 series of Wallplate Temperature Sensors are
designed to be used with the Excel 5000 family and other
Honeywell controllers. The C7772 sensors provide a resistive
output signal proportional to sensed room or space
temperature. The C7772 is well suited for low-profile wallmounted applications where durability and tamperproof
construction is desired, such as schools, prisons and
institutions.
