RAYTEK

RAYTEK, a brand established in 1963 and now part of Fluke Process Instruments, is a manufacturer of non-contact infrared temperature sensors and accessories. The product line includes fixed-mount infrared temperature sensors, right-angle mirrors, air purge collars, and mounting brackets. These devices are used for non-contact temperature measurement in industrial processes where contact sensors are impractical due to moving targets, high temperatures, or hazardous environments. Key specifications across the range include IP65-rated housings for dust and water ingress protection, adjustable emissivity settings (typically 0.10 to 1.10) to accommodate different surface materials, and distance-to-spot ratios such as 4:1 and 13:1, which define the measurement area relative to distance. Sensors operate on 24V DC and are available with cable lengths of 3.2 ft or 10 ft. Thread sizes are standardized at 3/4"-16 UNF for mounting compatibility. Compliance with CE and ISO 9001 standards is indicated on several models. Accessories like the right-angle mirror (for the CM Series) and air purge collar (for the CI Series) extend the application range by enabling angled viewing or keeping optics clean in dusty environments. 3G Electric stocks multiple RAYTEK SKUs, including sensors and accessories, and provides datasheets and logistics support for global procurement. The product range supports applications in industrial heating, manufacturing, and process control where precise, non-contact temperature monitoring is required.

Common Applications

  • Industrial heating — RAYTEK fixed-mount sensors (e.g., RAYCMLTJ) monitor temperature in furnaces and ovens for process control.
  • Manufacturing — RAYTEK CI Series sensors with air purge collars measure temperature on moving conveyor belts in dusty environments.
  • HVAC — RAYTEK sensors with 13:1 distance-to-spot ratio (e.g., RAYCMLTV) check duct temperatures from a distance.
  • Food processing — RAYTEK right-angle mirror (CM Series) enables temperature measurement in tight spaces on packaging lines.
  • Plastic molding — RAYTEK fixed-mount sensors (e.g., RAYCI1B10L) monitor mold temperatures without contact.
  • Metalworking — RAYTEK sensors with adjustable emissivity measure surface temperatures of hot metals during forging or rolling.

Frequently asked questions

Common questions about RAYTEK from 3G Electric.

What is the typical IP rating for RAYTEK fixed-mount infrared temperature sensors?

RAYTEK fixed-mount infrared temperature sensors, such as models RAYCMLTJ, RAYCMLTK, RAYCI1B10L, and RAYCMLTV, are rated IP65. This means they are dust-tight and protected against water jets from any direction, making them suitable for use in industrial environments with exposure to dust, moisture, or washdown conditions.

What distance-to-spot ratios are available for RAYTEK sensors?

RAYTEK fixed-mount sensors are available with distance-to-spot ratios of 4:1 (e.g., model RAYCI1B10L) and 13:1 (e.g., models RAYCMLTJ, RAYCMLTK, RAYCMLTV, RAYCMLTV3, RAYCMLTK3). A 13:1 ratio means that at a distance of 13 inches, the sensor measures the temperature of a 1-inch diameter spot, allowing for accurate readings from a greater distance.

What is the purpose of the RAYTEK right-angle mirror accessory for the CM Series?

The RAYTEK right-angle mirror (part number XXXCMACRA) is an accessory designed for the CM Series infrared temperature sensors. It allows the sensor to measure temperature at a 90-degree angle, which is useful in confined spaces or when the target is not directly accessible. The mirror adapter redirects the sensor's line of sight without moving the sensor body.

What is the function of the RAYTEK air purge collar for the CI Series?

The RAYTEK air purge collar (part number XXXCIAP) is an accessory for the CI Series infrared temperature sensors. It connects to a compressed air supply to create a continuous flow of air across the sensor's lens, preventing dust, smoke, or other particulates from accumulating on the optics. This maintains measurement accuracy in dirty or high-particulate environments.

What thread size and type do RAYTEK fixed-mount sensors use for installation?

RAYTEK fixed-mount infrared temperature sensors, including models RAYCMLTJ, RAYCMLTK, RAYCI1B10L, RAYCMLTV3, RAYCMLTV, and RAYCMLTK3, use a 3/4"-16 UNF thread. This standardized thread size allows for mounting into compatible brackets, stands, or custom fixtures using standard hardware.

What standards do RAYTEK sensors comply with?

RAYTEK sensors are manufactured under ISO 9001 quality management systems and comply with CE directives, including EC Directive 2004/108/EC (electromagnetic compatibility) and EC Directive 2004 (likely referring to the Low Voltage Directive or EMC). These certifications indicate that the sensors meet European safety and performance requirements.
