Supported Applications
The Omega ON-950 Series consists of bolt-mount thermistor sensors designed for mounting into #8-32 threaded holes, with a 4 mm thread option available. These surface temperature sensors feature small thermal mass to provide rapid response to temperature changes.
Operating Conditions & Performance
The series supports two primary performance envelopes based on the selected thermistor element:
- Standard Interchangeability: ±0.2°C over a 0 to 70°C range with a maximum working temperature of 100°C (212°F).
- Tighter Interchangeability Options: ±0.1°C over a 0 to 70°C range using specific thermistor part numbers, limited to a maximum working temperature of 75°C (165°F). Storage and working temperatures for best stability are -80 to 75°C (-110 to 165°F).
The housing is constructed from 300 Series stainless steel. The standard electrical connection utilizes a 28 AWG stranded PFA insulated and jacketed cable with stripped leads.
Configuration Options
The ON-950 series offers configurable dimensions, resistance values, mounting threads, and connector types to accommodate specific installation requirements. The model number follows the format: ON-950-<RESISTANCE_CODE>-<CABLE_LENGTH_CODE>-<CONNECTOR_CODE>.
Sensor Elements & Resistance
The series is available in five resistance values at 25°C:
- 2,252 Ω (Standard: ON-950-44004; Tighter Interchangeability: 44033)
- 3,000 Ω (Standard: ON-950-44005; Tighter Interchangeability: 44030)
- 5,000 Ω (Standard: ON-950-44007; Tighter Interchangeability: 44034)
- 10,000 Ω (Standard: ON-950-44006; Tighter Interchangeability: 44031)
- 30,000 Ω (Standard: ON-950-44008; Tighter Interchangeability: 44032)
Cable & Connector Options
- Length: Standard cable length is 300 mm (12"). Additional lengths are available by adding the required length in inches to the end of the model number.
- Termination: Stripped leads are standard. A phone plug connector is available as an option; add "-PP" to the model number.
Mounting & Housing Dimensions
- Housing Material: 300 Series stainless steel with a 6 mm (¼ in) hex head and 4.3 mm (0.170 in) body diameter.
- Overall Length: 25 mm (1 in).
- Thread Type: #8-32UNC-2A mounting thread is standard. A 4 mm mounting thread is available by adding "-M4" to the model number.
Key Product Differences
Variants within the ON-950 series differ primarily in thermistor interchangeability class, resistance value at 25°C, cable length, and connector type. Standard models (e.g., ON-950-44006) provide ±0.2°C accuracy up to 100°C (212°F). Models utilizing the optional tighter interchangeability thermistors (substituting part numbers such as 44031 for a standard element) offer ±0.1°C accuracy but are limited to a maximum working temperature of 75°C (165°F).
Physical variations include the addition of "-M4" for metric threading and suffixes indicating custom cable lengths or phone plug connectors (-PP). The series does not list specific output signal types, as these sensors function as resistance elements requiring external excitation.
