Fixed IR sensor for 3/4"-16 UNF2A ports

The Raytek RAYCI1A10L is a fixed-mount infrared temperature sensor designed for permanent installation in a 3/4 inch -16 UNF 2A threaded port. It provides non-contact temperature measurement across a 32 to 662 degree Fahrenheit range with a fixed emissivity of 0.95 and a 4:1 distance-to-spot ratio. The IP65 and NEMA 4 rated enclosure suits harsh industrial or automotive environments.

Check thread size emissivity and cable reach

Verify that the mounting port matches the 3/4 inch -16 UNF 2A thread specification before ordering. Confirm the target material emissivity is compatible with the fixed 0.95 setting, as the sensor does not offer adjustment. Ensure the 3.28 foot cable length reaches your data acquisition or control system, and note the 50 ohm output impedance for proper signal termination.

Replaces handheld probes or lower ratio sensors

This unit upgrades from handheld infrared thermometers when continuous automated monitoring is required at a fixed measurement point. The jump is worth it for processes needing permanent IP65 protected installation with a 4:1 optical resolution that handheld tools cannot maintain consistently. It does not suit applications requiring variable emissivity settings or a narrower spot size at distance.

Questions about this item

Does the Raytek RAYCI1A10L sensor include mounting hardware or a power supply, or must they be purchased separately?

The sensor is supplied with a 3.28 ft cable. The UNF2A 3/4"-16 thread allows direct mounting into a compatible port. A separate power source matched to the 50 ohm impedance is required.

The emissivity is fixed at 0.95 — how do I decide if this version suits my application?

Fixed 0.95 emissivity works well for most painted, oxidised or non-metallic surfaces between 32 and 662 °F. If you measure polished metal or materials with lower emissivity, an adjustable-emissivity model would be more appropriate.

What does the 4:1 distance-to-spot ratio mean for actual temperature readings on the production line?

At a 4 inch working distance the measurement spot is 1 inch in diameter. To capture the full target, keep the sensor close enough that the spot stays within the object you are measuring.
