The Raytek® CM sensor provides the
advantages of infrared temperature
measurement in a powerful, compact,
integrated sensor. Designed for easy
integration, the CM sensor can easily
replace traditional contact probes with a
J-type or K-type thermocouple output, or
with a user scaleable 0-5 volt output, if
your application is susceptible to noise.

The CM sensor is designed to measure
target temperatures ranging from -20°C
to 500°C (-4°F to 932°F). The CM's
onboard electronics are protected by a
rugged IP 65 (NEMA-4) stainless steel
housing, allowing the sensor to function
in ambient temperatures to 70°C (160°F)
without cooling.

Although small in size, the CM is loaded
with advanced features. An RS232 digital
interface allows the user to configure all
programmable sensor variables with the
powerful DataTemp Multidrop software
included with each sensor. These include
a 24 volt DC alarm output triggered by
target temperature or head ambient
temperature, peak hold, valley hold or
variable averaging signal processing,
adjustable target emissivity settings and
adjustable window transmissivity setting.
The built-in sensor health LED provides
a convenient on-line indicator of the
sensor's operating status and aids in
troubleshooting initial sensor set up.

Compact. Powerful. Easy to install.
Affordable.

The Raytek CM sensor is the
ideal solution for both OEM and end-user
applications.

Nominal Optical Specifications

D:S is the optical resolution expressed as a ratio of the distance to the target

spot divided by the diameter of the spot.

Nominal spot size based on 90% energy.
