Telaire T6613
Manufacturer-verified NDIR CO₂ sensor module.
Key Specifications
Product Positioning
Telaire T6613 is part of TELAIRE / AMPHENOL’s NDIR CO₂ sensing portfolio for OEM integration.
T6613 Range and Digital Integration
Choose the ordered range: The profile lists 2,000 ppm and 5,000 ppm configurations, not a guaranteed continuously switchable 2,000–5,000 ppm span on all delivered T6613 modules. Document the exact part number before choosing the display full scale or building a ventilation control loop.
Digital control integration: “Digital” is not a complete protocol specification. Check the Telaire interface guide for signal levels, start-up delay, command map and the handling of communication and out-of-range errors. Do not assume a protocol is shared with other Telaire generations.
Design validation: With no quantitative accuracy in this AirAlign card, leave the accuracy requirement open until the correct manufacturer datasheet is attached. Mounting airflow, dust ingress, humidity exposure and baseline recovery can influence system performance.
Alternative: T6615 is listed as dual-channel and up to 50,000 ppm; that is not evidence that it shares T6613’s mechanical footprint or interface.

Telaire T6613 — 12-pin NDIR CO₂ OEM module: OEM specifications and integration
The manufacturer publishes model- and range-specific measurement data; numerical test values, measurement accuracy and digital output envelope are not interchangeable.
| Specification | Official product data | Engineering consequence |
|---|---|---|
| CO₂ measurement | Factory calibrated 0–2,000 or 0–5,000 ppm variants | Select actual –5K suffix before specifying concentration ceiling. |
| Accuracy 400–1,250 ppm | ±30 ppm OR 3% reading, whichever is greater | This is not ±(30 ppm + 3%) additive formula in this band. |
| Accuracy 1,250–2,000 ppm | ±(30 ppm + 5% reading) | Stricter lower-band limits do not extend to the upper band. |
| Communications | UART 19,200 baud or I²C slave up to 100 kHz; optional 0–4 V analog | Do not assume RS485 Modbus directly from a TTL/UART header. |
| Power draw | 5 V regulated ±5%; 0.9 W peak and 0.165 W average | Board supply must accommodate optical source pulses. |
| Update / response | 4-second data update, T90 <2 min, operational <2 min, ~10 min full accuracy | Gas chamber diffusion, not register polling, limits response. |
| Assembly and operating conditions | ~57.15 × 34.67 × 15.24 mm; 12-pin male header footprint; 0–50 °C operating | Larger than T6713 and T6703; not mechanically drop-in. |
| Field handling | ABC Logic; flowthrough option 40–50 cc/min | Fresh-air baseline and flow assumptions important in process enclosures. |
Application, calibration and design details
T6613 is a dedicated OEM CO₂ sensor with significantly different package and connection from the T67xx miniature family. The 0–4 V output and 5 V input cannot be wired directly to a 4–20 mA loop without a configured transmitter stage. Calibration is factory performed, while ABC Logic assumes periodically low-CO₂ air; process cultivation or closed occupancies can violate that assumption. The source describes different formulas for accuracy below and above 1,250 ppm. Use the actual part/suffix and reference gas checks when building precise DCV threshold alarms.
