SA2C-SA2F-RTD

Supported Applications

The Omega SA2C and SA2F series are flexible, self-adhesive silicone molded RTD surface sensors designed for temperature measurement on irregular or curved surfaces. The product overview identifies these as "Flexible Molded RTD Surface Sensors" that mount to any shape using an adhesive back.

Operating Conditions & Performance

The series operates within a documented temperature range of -50 to 200°C. Measurement is performed using a precision 100 Ω, Class "A" DIN Platinum element in a standard 4-wire configuration. The sensor body dimensions are specified with a maximum thickness of 6.4 mm (0.25") and an overall height of 2", while the width measures 0.63".

Configuration Options

The series offers configurable cable lengths, electrical connection types, and optional connectors to accommodate specific installation needs.

• Cable Construction: Standard cables are #26 AWG stranded nickel-plated copper, PFA insulated and jacketed. The standard length is 1 m (40").
• Electrical Connections: Stripped leads are the standard configuration; connector options are available.
• Connector Options: A TA3F audio connector can be added by appending "-TA3F" to the model number. Miniature connectors are available with the addition of "-MTP" to the model number.
• Cable Lengths: Standard lengths include 1 m (40") and 2 m (80"). Longer cable lengths can be configured by changing the length suffix in the model number, priced per foot for additional cost. Available variants listed include configurations up to 3 m (120"), as well as metric designations such as "-1M", "-3M", and "-5M".

Key Product Differences

The series is divided into two primary model families: SA2C and SA2F. Both utilize the same 100 Ω, Class "A" DIN Platinum element and share identical dimensional specifications for the sensor body (height of 2", width of 0.63"). The documented distinction between these models in the provided data is limited to their model number prefixes; both are described as flexible sensors with adhesive backs.

Model numbers follow the format SA2C-RTD-3-100-A-<LENGTH> or SA2F-RTD-3-100-A-<LENGTH>, where <LENGTH> denotes the cable length in inches (e.g., 40, 80, 120) or meters. For example, SA2C-RTD-3-100-A-40 represents a 1 m (40") configuration.
