FEATURES
• Easy mounting
• Rugged construction
• Replaces the serie 2322 640 7....
• Compliant to RoHS directive 2002/95/EC and in
APPLICATIONS
Temperature measurement, sensing and control.
Suitable for many applications, especially when a good
electrical insulation and a good thermal contact with the
chassis is required.
DESCRIPTION
The thermistors are made of NTC ceramic material reflow
soldered between two solid tinned copper or nickel wires and
potted in the head of passivated aluminum srew size M4.
PACKAGING
The thermistors are packed in cardboard boxes; the smallest
packaging quantity is 100 units.
MARKING
The last 4 digits of the catalog number are printed on the stud
in accordance with the information in Electrical Data and
Ordering Information Table.
MOUNTING
By means of a washer and M4 nut supplied with the device
or in a threaded screw hole. Applied torque shall not exceed
1.2 Nm. Leads to be soldered or crimped.
DIMENSIONS in millimeters
accordance to WEEE 2002/96/EC
