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).
