Notes: For additional cable length, add required length (in inches) to end of the model number for additional cost. For a phone plug, add “-PP”
to the model number for additional cost. For tighter interchangeability, substitute the thermistor part number from the table below and add the
price listed to the sensor price.

Ordering Examples: ON-909-44004-40-PP, surface thermistor sensor with a resistance of 2252 Ω at 25°C and an interchangeability of ±0.2°C,
1 m (40") of cable and a phone plug connector.

ON-909-44032-40-PP, surface thermistor sensor with a resistance of 30000 Ω at 25°C and an interchangeability of ±0.1°C, 1 m (40") of cable
and a phone plug connector.
