DESCRIPTION
• Miniature NTC thermistor body mounted on an insulated
flex foil and topped with an insulating epoxy glob top
• For flat surface temperature sensing with low thermal
mass and rapid response time
MOUNTING
• The stiff flat sensing area can be pressed against a flat
surface by means of insulating material (silicone foam), by
spring force or by taping it with a double sided
temperature resistant adhesive
• The sensor contacts can be connected to a PCB
counter-connector or wire-to-wire connector or soldered
to conductors, or crimped with FFC connectors and ZiF
connectors
• A mating connector can be for example a 0.5 mm pitch
7 poles connector for FPC, with top contacts, accepting
4 mm FPC width, ZIF or non-ZIF versions. The poles
(1 + 2) and (6 + 7) can be used for the electrical
connection. For example in SMT versions : TE 1734839-7,
Hirose FH34S-7S-0,5SH(50), Molex 054550-0771, Molex
052745-0797
• Consult Vishay for other screw sizes, lead length,
insulation, connector crimping or other features
Note
• FFC/FPC = Flexible Film Circuit/Flexible Printed Circuit
