1. Response time in silicone oil MS 200/50. This is the time needed
for the sensor to reach 63.2% of the total temperature difference
when subjected to a temperature change from 25 °C in air to
85 °C in oil.
2. Wire length and wire type are optional on request. The products
can be provided with a connector on request.
3. Tighter tolerances on R₂₅ are available upon request.
These thermistors have a negative temperature coefficient.
The epoxy-coated type (2322 641 2....) consists of a chip
with UL wire and is lacquered and insulated with black
epoxy.
The sleeved type (2322 641 3....) and the brass-pipe type
(2322 641 4....) are suitable for application in various
environmental conditions.
MARKING
UL mark on wire, no mark on body.
PACKAGING
The thermistors are packed in cardboard boxes; each box
containing 500 pcs.
