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
