The Thermal Protector 01-SMD from Thermik Corporation is a normally closed temperature controller designed for surface mount technology (SMT) assembly. It features automatic resetting and provides overheat protection by utilizing a bimetallic disc that reacts to ambient temperature changes. The device operates within a nominal switching temperature range of 70 ¬8C to 150 ¬8C, with a tolerance of ¬±2.5 K or ¬±5 K. It can handle operational voltages up to 250 V AC and 14 V DC, with a maximum switching current of 15 A for DC applications. The 01-SMD has a compact design with a diameter of 9.0 mm and an installation height starting from 2.5 mm. It is constructed with silver contacts for excellent thermal stability and is compliant with RoHS standards. The product is suitable for applications requiring reliable temperature control and is approved for use under IEC, ENEC, and VDE standards.
The switchgear of type series 01 is fixed in a positive lock and is self-aligning between the floor of a conductive housing (1) and a contact cap which is made of steel (2) and insulated from it, plus an integrated stationary silver contact (6) which closes the housing like a button cell. At the same time, the spring snap-in disc (3) which forms the current transfer element bears the movable contact (4) and discharges the flow of current and self-heating from the bimetallic disc (5) by exercising consistent, steady contact pressure. The bimetallic disc (5) is held on the one movable contact (4) which sticks out through this without having to be welded or fixed. As such, it can continually work (exposed) and only reacts to the ambient temperature in the device to be protected. When the rated switching temperature is reached, the bimetallic disc (5) snaps into its inverted position and pushes the spring snap-in disc (3) downwards. The contact is abruptly opened and the temperature rise of the device to be protected is disrupted. If the ambient temperature now falls, the bimetallic disc (5) snaps back into its start position when reaching the defined reset temperature and the contact is closed again.
