Notes
1. Measured with AMP connectors in still air with solid copper wires
of 1 mm diameter.
2. The response time is the time necessary to change 63.2 % of the
total difference between the initial and the final body
temperature, when subjected to a step function change in
ambient temperature.
Step change:
a) initial temperature: air at 25 °C
b) final temperature: water at 100 °C
3. The temperature gradient is the difference per degree Celsius
between the true temperature of the liquid (water) and the
temperature measured by the sensor.
FEATURES
• High mechanical strength
• AMP connectors for easy connection
• Excellent accuracy over a wide temperature range
• Old part number was 2322 640 90042
• Component in accordance to RoHS 2002/95/EC and
WEEE 2002/96/EC
APPLICATIONS
• Sensors for water temperature control in, for example:
– washing machines
– dish washers
– heat pumps
– electric boilers.
These thermistors have a negative temperature coefficient.
The device consists of a ceramic material which is mounted
in a capsule of stainless steel and provided with two 6.3 mm
tinned bronze spade connectors.
The device is non-flammable and the housing is stainless
steel in accordance with “DIN 1.4301” (× 5 CrNi 18 9).
MOUNTING
Connect to two FASTONS 6.3 x 0.8 or equivalent.
PACKAGING
The thermistors are packed in cardboard boxes; the smallest
packaging quantity is 50 units.
