Description:
JUC-31F series Miniature Thermal Switch is a snap-action thermostat
with a bi-metal disc as the temeprature sensing element. Its main
working principle is to control the temperature by opening or
closing the bi-metal strip. It stays at normally closed/normally
open status, it opens/closes when temeprature rising and
closes/opens when temperature decreasing. It has the
characteristics of snap action,high accuracy, long life cycle, high
sensitivity, high reliability, small size, light weight, easy
installation. JUC-31F Miniature Thermal Switch has been granted
national patent, and has passed UL, TUV, CE, CQC, CB and ROHS. It
also has passed the 100,000 life test of UL laboratory. It is
widely used in printed circuit board equipment, power supply
equipment, audio amplifier, welding equipment, automation equipment
and instrumentation for temperature control and temperature
protection.
Applications:
● Printed circuit board equipment
● Power supply equipment
● Audio amplifier
● Welding equipment
● Automation equipment
● Instrument and apparatus
● Charger
