You are bidding on (1) NEW Elmwood 2450 Thermal Sensor, these are NORMALLY OPEN. The part number is 2450 87-265 F131. They close at roughly 55°C. We have been unable to find a data sheet for this particular sensor, but we do know it was used in the Hafler DH500, P500, and XL600 audio amplifiers as a thermal switch to increase the speed of a cooling fan when the amplifier temperature got hot enough; so it’s NORMALLY OPEN (we verified that it is) and then closes when it gets hot enough ( roug hly 55°C), in the Hafler case, increasing the fan speed by bypassing a resistor. Hopefully that gives a general idea of it’s temperature operation . In case it helps, this sensor goes by the Hafler part numbers SWH-119 or SF025; both are the same sensor. If anyone has any specific information on this Elmwood Sensor, or a data sheet, please drop us a note so we can add the information to the listing to help others find the part they need.
