Crimp style receptacles that are designed
to mate with headers conforming to MIL-C-
83503. The low insertion force contacts
reduce surface finish wear and resist stress
relaxation very well.
Features––––––––––––––––––––––––
• Secure lock device
The locking levers are engaged by inserting the receptacle into
the header. This ensures a firm connection that’s highly
resistant to impact and vibration.
• Housing lances
The contact retention lances on the resilient housing allow
visual confirmation of contact lock-in for easy and secure
insertion.
• Low insertion force contact
The low insertion force contacts reduce surface finish wear and
reduce the effects of stress relaxation.
• Anti-misinsertion feature
The guide devices of both housing and header prevent reverse
connector insertion.
