Littelfuse Inc. today announced its new EL731 AC/DC Sensitive Earth-Leakage Relay, which can detect ground currents—even in resistance-grounded electrical systems—all the way down to 0 Hz. This makes it ideal for protecting variable-frequency drives (VFDs) that may operate at low speeds, during which AC current approaches DC.

The Deeter Group announced the introduction of its Wireless Sender which increases the possible applications of the recently launched Deeter Wireless Sensor System for industrial measurement and control.

Crydom, has expanded its Series H1 of high voltage AC output Solid State Relays. Complementing the successful Crydom Series H1 1200 Volt Blocking models, the new models now offer even higher levels of breakdown voltage and noise immunity (>1600 volts) for applications in installations where electrical transients are common and might otherwise damage less robust SSRs.

Crydom's new SeriesOne DR family of AC and DC output DIN Rail mounted Solid State Relays are intended for use in heating, lighting and motion control applications where DIN Rail mounting is preferred and higher output power ratings are required. Featuring a unique proprietary thermal management design with no exposed hot metal surfaces for safety, the SeriesOne DR family includes AC output ratings at 40°C ambient for single channel models of eit...

Crydom's new EL series of Compact Solid State Relays include models with output ratings up to 20 Arms from 24 to 280 VAC or 10 Adc from 3 to 100 VDC with optional external heat sink. Logic compatible control input versions include 5, 12 or 24 VDC. Output termination is via 0.25 (6.35 mm) quick connect terminals, while input terminals are 0.187 (4.75 mm) quick connects.

Crydom introduces the PowerPlusDC Series of DC output SSRs. Complementing its extensive line of both AC and DC output SSRs, the PowerPlusDC Series features traditional Crydom Series 1 panel mounted style SSRs with ratings from 1 to 100 amps, at 1 to 400 VDC in a 40°C ambient temperature. The PowerPlusDC Series feature available Logic Compatible Control Inputs of either 4 to 32 VDC or 90 to 140VAC, with standard LED input status indicator.

RF Solutions has launched its new FireBlade remote control system, which is housed in a rugged IP68 weatherproof enclosure. Supplied with an antenna and delivering a transmitting range of up to 1,000 metres, the ‘FireBlade’ system can be used in a variety of applications. These include lighting control, remote switching, industrial remote switching and access control. Each individual switch on each of the transmitters may be paired wi...

According to the Twelfth Five-Year Special Plan for LED Technological Development issued recently by the Ministry of Science and Technology, by 2015, the scale of LED industry will reach 500 billion Yuan, with 50 pilot model cities of “Achievements Show of Ten Pilot Cities” and 20 distinctive industrialization bases of strong innovation ability established. The LED industry, which has been developing rapidly, will continue fueling the...

The new A1171 from Allegro MicroSystems Europe is an ultra-sensitive micropower Hall-effect switch with latched digital outputs and either unipolar or omnipolar actuation. It features operation at low supply currents and voltages, making it ideal for battery-operated applications in portable or handheld communications and computer equipment.

Toshiba Electronics has announced two new miniature photocouplers that are ideal for office equipment, home appliances, solid state relays and other applications demanding high impulse noise immunity.
