Notes: For additional cable length, add required length (in inches) to end of the model number for an additional cost. For a phone plug, add  
“-PP” to the model number for an 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-960-44004-PP, flange-mount thermistor sensor with a resistance of 2252 Ω at 25°C and an interchangeability of 
±0.2°C, 300 mm (12") of cable and a phone plug connector. 
ON-960-44034-40-PP, flange-mount thermistor sensor with a resistance of 5000 Ω at 25°C and an interchangeability of ±0.1°C, 300 mm (12") 
of cable and a phone plug connector.
