Home » Snap Disc Thermostat » SN-9 (N-9) Miniature Thermostat
|- Snap action disc
- High thermal sensitivity
- Compact, slim design
- Automatic, one shot modes available
- Variety of mounting brackets and terminals available
- Low cost
- Long contact life
The applications are divided in two categories:
Temperature control: Here the thermostat is used to control temperature of end product between two levels.
Thermal overload protection: Here the thermostat is used to protect end product from overheating caused by overloading, blocked ventilation, increased ambient temperature, etc.
Examples of applications:
N-9 is available in two single poles, single throw (SPST) switching action:
Automatic Reset: Can be built to either open or close its contacts on temperature rise.BR>
One shot thermostat: Available with contacts that open on temperature rise, and which never reclose till the ambient temperature drops below 0°C.
|The insulation base of N9 is made up of PPS (Polyphenylene sulphide). This is a high performance engineering plastic perfectly suitable for high temperature applications.|
N-9 is available in several mounting configurations.
M0 Mounting Bracket: This mounting bracket has no mounting holes. The Disc enclosure is available in Aluminum and Brass
M6 Surface Mount Bracket: The heat sensing bimetal disc is positioned firmly against the mounting surface so it senses the actual mounting surface temperature.
TS: N-9 is supplied crimp type terminals.
T 4.8: We also have 4.8mm x 0.5mm quick connect terminals.
These terminals are available in flat or vertical position in nickel plated brass or nickel plated steel.
|Temperature, Differentials and Tolerances|
The snap disc thermostat has a snap action opening and closing of contacts, which ensures no sparking or chattering.
N-9 is supplied to customer specified open and close temperature set points with a tolerance on both set points. Temperature difference between cut-off and cut-in temperature is called differential temperature.
- Cut-off Temperature range: for N-9 50 to 160°C
- Cut off Temperature Tolerance: ± 4%
- Differential Temperature: 10-40°C
