Description:
KSD-01F 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. We use international TO220/Y220 standard
packingJUC-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.

Note:
1 , using the contact temperature installation should be charged
with the metal cover up snapping apparatus mounting surface , to
ensure that the temperature effect , should be coated with thermal
grease or other similar thermal properties of the medium in the
surface temperature .
2 , the installation can not cover up the top collapsed , loose or
deformed , so as not to affect performance.
3, can not allow the liquid to penetrate the internal temperature
may not make the shell cracks , are not free to change the shape of
the external terminals.
4 , the product is not greater than 5A current in the circuit ,
chose the copper cross-section 0 5-1 mm 2 wire connection ; . No
greater than 10A current in the circuit , chose the cross-section
of 0.75-1.5 mm 2 copper wire connection.
5, the product should be less than 90% relative humidity , ambient
temperature is below 40 °C ventilated, clean, dry , non-corrosive
gases stored in the warehouse .
KSD-01F classification , in accordance with the temperature to
points, can also be classified according to the material , you can
also follow the installation way points.
According to the nature of the action : the action can be divided
into normally open(H Type) and normally closed(D type).
