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 87mm
2
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).
RoHS compliant since date code: 0431B8
