T6615-R12

Amphenol Advanced Sensors (Telaire)
Carbon Dioxide (CO2) Sensor 0 V ~ 4 V
Active

Overview

The T6615-R12 is a dual-channel CO2 sensor module designed for accurate carbon dioxide measurement in the 0 to 2,000 ppm range. It utilizes a Non-Dispersive Infrared (NDIR) optical system to ensure long-term stability and is factory calibrated for ease of integration. This module is particularly suited for environments where Automatic Background Calibration (ABC) logic cannot be implemented.

Why Choose This Part

The dual-channel optical system provides superior long-term stability by compensating for light source aging. It supports both UART and 0-4V analog outputs, offering flexible interfacing for various microcontroller and PLC systems. With a 10 percent accuracy rating and 5VDC operation, it is a robust solution for OEM air quality applications.

Applications

Demand-Controlled Ventilation
Used in HVAC systems to monitor indoor air quality and optimize fresh air intake based on occupancy levels.
Greenhouse Monitoring
Maintains optimal CO2 concentrations for plant growth where constant high CO2 levels prevent standard auto-calibration methods.
Industrial Safety
Provides reliable CO2 monitoring in confined spaces or industrial processes where dual-channel stability is required.

Key Specifications

Type Carbon Dioxide (CO2)
Output 0 V ~ 4 V
