Fits compact multi-head IR sensing where you need Raytek MI3 Plug & Play heads on one communications box—LT ranges from −40 °C with optional high-temp heads to 1800 °C class.
Key advantages
- Multi-head — Up to 8 sensing heads per communications box with Plug & Play detection
- LT range — −40…600 °C standard LT; extended LT to 1000 °C; 1M/2M/G5 higher to 1800 °C class
- Accuracy class — ±1 °C (mA/V); ±1.5 °C (thermocouple output)
- Response — Head response down to ~10 ms (model dependent)
- Hot ambient — LTH heads to 180 °C ambient without cooling
Typical applications
- Web/roll temperature monitoring.
- Thermoforming / plastics lines.
- Multi-zone kiln or oven spots.
Selection guide
- Head spectral class — LT vs 1M/2M/G5
- Communications box — Head count and I/O
- Output — mA/V vs TC
- Ambient / cooling — Head ambient rating
Common mistakes
- Mixing incompatible head families on one box.
- Ignoring spot size vs distance.
- Running heads above ambient rating without cooling.
When to RFQ / what to tell us
- Head type/count, box, outputs.
- Process T, ambient, quantity, ship-to.
