Fixed infrared sensor for industrial monitoring

The Raytek fixed infrared temperature sensor measures surface temperature without contact. It is suited for process control, preventive maintenance and quality checks where a probe cannot touch the target. The unit operates from 32 to 240 degrees Fahrenheit.

4:1 distance-to-spot ratio defines measurement area

At a 4:1 ratio the sensor spot diameter equals one quarter of the distance to the target. This ratio determines the smallest feature the sensor can resolve and must match the application geometry.

UNF 3/4"-16 thread mounts in standard ports

The sensor installs via a 3/4 inch UNF 2A thread into existing ports or brackets. Cable length is 10 feet for routing to a controller. IP65 and NEMA 4 ratings protect against dust and water jets; ensure the mounting face seals cleanly to maintain the rating.

Questions about this item

How does the 4:1 distance-to-spot ratio affect the measurement area when the sensor is mounted in a machine?

The 4:1 ratio means the measured spot diameter is one-quarter of the distance from the sensor to the target. At a 10 ft cable length the spot size scales directly with the working distance you choose.

What does the 3/4"-16 UNF 2A thread specification determine for installation?

The 3/4"-16 UNF 2A thread defines the mounting interface. It requires a matching tapped hole or nut with the same diameter, 16 threads per inch, and a class 2A external fit.

What are the physical mounting requirements for the IP65 and NEMA 4 rated housing?

The sensor body carries an IP65 and NEMA 4 enclosure rating, so the mounting location must provide a sealed fit for the 3/4"-16 UNF 2A threads and protect the 10 ft cable entry from dust and water jets.
