MINIATURE RELAY
2-CONTACT 1A (FOR SWITCHING SIGNALS)
FTR-B3 Series
■ FEATURES
●These are flat type ultra miniature (SMT), 5.2±0.2mm height (through hole) relays for telecommunication and data networking equipments, made of high heat resistant material, which can support IRS and VPS methods.
●Ultra slim and light weight with a 5.25±0.2 mm height and approximately 0.8 g weight, and an 87mm2 mounting area. Most suitable for decreasing size and weight, space saving and high density packaging of equipment.
●Contact spring has superb high frequency characteristics.
●High insulation design conforming to the Bellcore, FCC standard, with a minimum of 1.6 mm between coil and contacts insulation distance, an AC 1.5kV coil contact withstand voltage, and a 2.5kV coil-contact withstand surge voltage.
●High efficieny polar electromagnet structure implements a140mW low coil power consumption. A power saving latch type is also available,
●Gold-plated silver alloy bifurcated contacts having high contact reliability.
●UL, CSA recognized. Confirms to IEC 60950, UL1950, EN60950. Spacing & high breakdown voltage (Basic insulation, 150 working volts, pollution degree 2).
