Rack and Panel Connectors Subminiature Rectangular

FEATURES

• Lightweight

• Polarized by guides or screwlocks

• Screwlocks lock connectors together to withstand vibration

and accidental disconnect

• Overall height kept to a minimum

• Floating contacts aid in alignment and in withstanding

vibration

• Contacts, precision machined and individually gauged,

provide high reliability

• Insertion and withdrawal forces kept low without increasing

contact resistance

• Contact plating provides protection against corrosion,

assures low contact resistance and ease of soldering
