One of TME's key service clients are the companies that need automation equipment and installation elements for their rooms, machine parks, warehouses, etc. When contacting companies interested in our offer, we always advise products from proven brands, that leave savings in the term. Manufacturer's components with a certain situation on the market and many years of experience do not usually fail, they are identified by mutual compatibility and compliance with a number of rules and standards.
Littelfuse offer in the TME catalog
The Littelfuse brand is undoubtedly one of the trusted and proven producers. This company is eminently famous as a distributor of security installations, although its offer goes far beyond this narrow field. Now, we present 3 sets of popular products that Littelfuse generates with its inherent quality and durability. These are Hall sensors, reed switches, and fuse sockets.
hall sensors
Hall sensors, that is, magnetic field sensors, belong to products with an exaggeratedly wide range of applications. They are most frequently used to monitor the status of rotating elements, for example, brushless motor shafts (BLDC), generators, starters, switches, but also to determine the status of alternative elements (industrial automation, power lines). production etc.). Littelfuse products are primarily intended for use in industrial conditions. They are identified by a high thermal tolerance (even up to 100°C). They can see a magnetized field from a distance of XNUMX mm or XNUMX mm (depending on the model).
Each and every one of the items in the TME offer are voltage sensors, which means that they are equipped with a 3-wire cable: power supply and output signal. The huge advantage of Hall sensors is their reliability, for example, resistance to vibrations that are generated in electric motors, such as rather harsh environmental conditions. At the same time, Littelfuse products can run at frequencies up to ten kHz. For rotating components, this means a theoretical speed monitoring capability of up to six hundred at zero RPM.
Reed switches and also magnets
While Hall sensors are electromagnetic devices, reed switches are mechanical components. There is a contact in the hermetically sealed glass, which switches the circuit under the impact of a magnetized field. This principle of operation has advantages over Hall sensors in certain situations. First, such an element generates a binary signal and does not need to be calibrated to work with the receiver. The second advantage of reed switches is the high values of the basic switch factors. For Littelfuse components, the maximum current is XNUMX mA, voltage XNUMX V, power XNUMX W (depending on the model). The contact configuration can be generally open or generally closed. In addition to this, reed switches can be used in the simplest of applications, for example as limit switches.
In both the case of Hall sensors and reed switches, the operation of the element requires a precise installation of the magnet (actuator), which will activate it. TME's offering includes Littelfuse magnets enclosed in simple-to-install housings. They can be fixed with bolts or screws. The catalog also includes variations with M8 thread and nuts.
fuse plugs
Miniature fuse accessories are another exciting range from Littelfuse. In many devices, both industrial and electronic and household appliances, cylindrical fuses are frequently used. They are also a recommended solution for builders dealing with low-volume production. The sockets for these protections are simple to install, often have an aesthetic finish, and allow fuse replacement without the need to open the device casing. Littelfuse offers a wide range of plugs designed for this kind of component.
The second popular solution (used not only in the automotive industry) is vehicle fuses. These inexpensive and simple to install components are used in road car conversion, motorhome and caravan construction, but also in industrial settings, for circuit protection in DC control systems etc. The configuration of Littelfuse fuse sockets leaves its simple installation. appliance installation. TME's offer includes both multipole and individual fuse plugs for installation on the cable.
