NTC Thermistors, Screw Threaded Sensors

Notes

• Insulated leads available upon request

FEATURES

• Easy mounting with screw

• Rugged construction

• Material categorization:



For definitions of compliance please see

www.vishay.com/doc?99912

APPLICATIONS

• Temperature measurement, sensing and control

• Suitable for surface temperature 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 12NC code 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.
