SA1-TH-44000

Supported Applications

The Omega SA1-TH Series consists of self-adhesive polyimide fast response thermistor surface sensors designed for "stick-on" or "cement-on" mounting to target devices. The series supports installation on both flat and curved surfaces, with a design that allows the sensor to be removed and re-applied.

Operating Conditions & Performance

The SA1-TH Series operates across two primary temperature envelopes depending on the selected thermistor element:

• Standard models (e.g., 44004–44008): Storage and working range of -80 to 120°C (-110 to 250°F) for best stability, with a maximum working temperature of 150°C.
• Optional tighter interchangeability models (e.g., 44030–44034): Storage and working range of -80 to 75°C (-110 to 165°F), with a maximum working temperature of 75°C.

Interchangeability is specified as ±0.2°C at 0 to 70°C for standard models and ±0.1°C at 0 to 70°C for optional tighter interchangeability thermistors. The sensors feature a polyimide construction with overall dimensions of 19 mm (0.75") x 25 mm (1").

Electrical Characteristics by Model

The series offers multiple resistance values at 25°C, selected via the model number:

• Standard Interchangeability (±0.2°C): Available in 2252 Ω, 3000 Ω, 5000 Ω, 10000 Ω, and 30000 Ω.
• Tighter Interchangeability (±0.1°C): Available in 2252 Ω, 3000 Ω, 5000 Ω, 10,000 Ω, and 30,000 Ω.

Configuration Options

The SA1-TH Series is configurable for specific installation needs through model number modifiers. Standard electrical connection includes 1 m (40") of 26 AWG stranded PFA insulated and jacketed cable with stripped leads.

• Connector Options: A phone plug connector is available by adding "-PP" to the model number.
• Cable Lengths: Additional cable length can be specified by appending the required length (in meters or feet) to the end of the model number for additional cost. Example: SA1-TH-44034-80-T indicates 2 m (80") of cable.
• Protection: Optional over braiding is available by adding "-SB" to the end of the model number, priced per meter or foot for additional cost.

Ordering Configuration Examples

The series uses a structured naming convention: SA1-TH-<RESISTANCE>-<LENGTH>-T. Specific configurations include:

• SA1-TH-44004-40-T-PP: Surface mount thermistor sensor with 2252 Ω resistance at 25°C, ±0.2°C interchangeability, 1 m (40") of PFA insulated and jacketed cable, and a phone plug connector.
• SA1-TH-44034-80-T-PP: Surface mount thermistor sensor with 5000 Ω resistance at 25°C, ±0.1°C interchangeability, 2 m (80") of PFA insulated and jacketed cable, and a phone plug connector.

Key Product Differences

Variants within the SA1-TH Series are distinguished primarily by thermistor resistance value at 25°C, interchangeability tolerance, maximum working temperature limits, and optional physical configurations. Standard models (44004–44008) provide a higher maximum working temperature of 150°C with ±0.2°C interchangeability. Optional tighter interchangeability models (44030–44034) offer ±0.1°C accuracy but are limited to a maximum working temperature of 75°C.

Physical variations include the standard stripped lead configuration versus the optional phone plug connector, and the availability of extended cable lengths or protective over braiding as specified in the model number suffixes.
