.050" Latch HEADERS .050" x .050" & .050" x .100" CENTERLINE HmHR SERIES Introduction: Adam Tech HMHR Series .050" Latch Headers are dual row, PCB mounted, shrouded headers with latches for use with dual row IDC female socket connectors. In addition to providing a shock and vibration proof connection the locking latches also act as ejectors to remove the mating socket. Our low profile, space saving design has a center slot for the socket’s polarization bump. Adam Tech’s Latch Headers are available in Straight PCB Mount, Right Angle PCB and SMT Mounting. Plating options include choice of Gold, Tin or Selective Gold Features: Integral Latches provide Shock and Vibration Proof connection Slot for IDC socket Polarization bump Straight PCB, Right Angle PCB and SMT versions Gold, Tin or Selective Gold plating Elevated option available Hi-Temp insulator available Mating Sockets: .050" X .050" & .050" X .100" Dual row IDC sockets Specifications: Material: Insulator: PBT, glass reinforeced, rated UL94V-0 Insulator Color: Black (Gray optional) Contacts: Brass ORDERING INFORMATION Plating: U = Gold over nickel underplate overall SG = Gold over nickel on contact area, Tin over copper underplate on tails. T = Tin over copper underplate overall Electrical: Operating voltage: 250V AC max. Current rating: 1 Amp max Contact resistance: 20 mΩ max. initial Insulation resistance: 5000 MΩ min. Dielectric withstanding voltage: 500V AC for 1 minute Mechanical: Mating durability: 500 Cycles min.
