Matsushita “T-Series” relays, for 30 W or 60 W nominal loads, meet the stringent demands of modern control, supervision, monitoring an test applications in the telecommunication, security, computer, medical, home appliance and automotive industries.
The ultra-small relay is capable of switching up to 30 W loads at 1 A max, 125 V max on each of its 2 or 4 changeover contracts. The relay, with greater coil sensitivity, is suitable for either through-hole applications or surface mounting.

Successfully diminishing the difference between the effective permeability and the initial permeability in a practical core, the H5C3 ferrite core material provides an excellent permeability reaching 13,000. This enables drops in size. The material is at work in the EP-style core. During manufacturing, sinter technology minutely controls the crystal structure of the H5C3 while maintaining excellent frequency characteristics. The H5C3 material has excellent temperature characteristics with a temperature coefficient of -0,5 to 1,5 (-30 ± 70˚C), improves the frequency characteristics in the high and low bands, reduces the insertion loss and operates in the temperature range of 0˚ to 40˚C.

To protect an IC from static surge invasion, the Emi Guard electromagnetic interference (EMI) filter provides a surge-absorbing function. Use of a proprietary three-terminal capacitor structure for the varistor allows it to absorb the static surge that invades the I/O pins of a semiconductor IC; this prevents IC destruction. ICs that static surges of 1 kV normally destroy will withstand static surges of 15 kV. The filter provides a static capacity of 130 pF + 20 per cent (at 1 kHz), a DC resistance of 200 to 500, a rated voltage of dc 25 V, a rated current of DC 20 mA, a surge withstanding current of 15 A (twice in 8/20 µs) and operating temperature range of – 25 to 85˚C.

A phase monitoring relay which ignores momentary voltage or phase failure has been launched by Carlo Gavazzi Electromatic.
Designated the Electromatic S-System Type 5074, the relay was developed as a result of frustrations in the British water industry where monitoring relays had the costly and annoying feature of switching alarms or shutting down equipment when a mere momentary loss or reduction in voltage of a phase was detected. The Electromatic solution has been to build a delay on de-energise timer into the relay unit so that a 10 second delay is experienced before the relay points release.

For large-screen and wide-screen TVs, the sockets come with double-focus gaps. The socket works from 29.1 to 32.5 mm and base pin circles of 15.24 mm. To save time in connection, the sockets come with two high-voltage wires that offer a snap-in format. Engineers can remove these wires from the socket easily, for maintenance. At the same time, the compact design saves space in board mounting. With a DC 20 kV/min. withstanding voltage, the socket offers an insulation resistance greater than 10,000Щ at DC 1 kV. The spark discharge start voltage equals DC 14 to 17 kV for the number 1 and 2 pins, DC 1.2 to 2.4 kV for number 8 pin, and DC 1 to 2.2 kV for the number 6, 7, 9, 10, 11 and 12 pins.
