Infrared Associates HCR-120 Optical Detector

The HCR-120 from Infrared Associates, Inc. is likely an optical or infrared detector designed for specialized applications, possibly in industrial, scientific, or military contexts.

Key Features & Likely Applications:

1. Technology:

   • Infrared (IR) Detection: Designed to sense IR radiation, possibly for thermal imaging, motion sensing, or spectroscopy.

   • Optical Sensing: May include photodiodes or phototransistors for precise light/wavelength measurement (e.g., laser detection).

2. Applications:

   • Industrial: Process control, flame detection, or temperature monitoring.

   • Scientific: Laboratory instruments, environmental sensing.

   • Defense/Security: IR surveillance, target tracking.

3. Design:

   • Durable Housing: Likely ruggedized for harsh environments.

   • Wavelength Range: Specific to IR spectrum (e.g., 700nm–14µm); exact range would depend on the sensor type.
