Rack and Panel Connectors
Subminiature Rectangular
FEATURES
SMP20
• 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.
