New High Power Miniature Molded SIP Reed Relay
Coto Technology has developed a new high-power miniature molded single-inline-pin reed relay which also addresses high board density and long life requirements. Coto Technology, Inc. has announced the release of the Coto 9094 series high power miniature molded SIP Reed Relay. The 9094 is a high-power, 20W version of Coto’s industry standard 9091 MiniSIP relay. The robust contacts and small size of the 9094 series make it ideal for ATE and other high-reliability test and measurement applications where high board density and long life are key requirements. The 9094 measures .600”x.150”x.275” and occupies 40 percent less board space than Coto’s popular 9001 series.
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin
Pressure sensors - commonly referred to as pressure transducers, pressure transmitters, pressure indicators or pressure switches - are used to measure the pressure of gases and liquids (fluids). Pressure is an expression of the force and is normally stated in terms of force per unit area. A pressure sensor will generate an electrical signal relating to the pressure imposed. This signal is either analogue or digital in more modern designs, although optical, visual and auditory signals are also common. Industrial pressure transducers normally have a diaphragm type design that uses strain gauges, which are either bonded to, or diffused into it, with the strain gauges acting as resistive elements. Under the pressure-induced strain, the resistive values change. In capacitive technology, the pressure diaphragm is a single plate of a capacitor that
Amid the multitude of advanced technologies being integrated into automated packaging operations today, one of the most reliable and versatile component s - inductive sensors - have been holding their own for decades. These simple sensors pack a big punch for OEMs and end users alike. We have compiled a list of the top five places where inductive sensors can positively impact productivity. Many factors make inductive sensing attractive to modern packaging applications. Because the sensor uses inductive variations in an internally generated magnetic field to detect the presence of metallic objects, there is no need for the sensor to physically contact the target itself. That feature alone offers a host of advantages - consistent performance fo r a variety of product or machine position and counting applications in harsh and sanitary environments, resistance to dirt and other substances, adaptability to high - speed functions , and many more.
