OFP® Receptacles and Sockets

Mill-Max receptacles and pass-through sockets with Organic Fibre Plug® solder barrier

OFP® Receptacles and SocketsMill-Max's Organic Fibre Plug® receptacles and sockets are discrete sockets for through-hole soldering into printed circuit boards. These open bottom receptacles are fitted with organic fibre plugs to prevent solder, paste or flux from contaminating the internal contact during the placing and soldering process. When the device/mating lead is plugged into the receptacle the OFP® is knocked out allowing the mating lead to pass through the fingers of the internal contact and make a reliable electrical connection.


  • After soldering, the organic fibre plug is pushed out of the receptacle when the component is plugged in.
  • Supplied as discrete receptacles or on carrier tape per EIA-481 for industry standard pick and place machines.
  • Designed for hand, wave or reflow soldering. The organic fibre plug prevents solder, paste or flux from contaminating the spring contact.
  • All Mill-Max receptacles use a precision machined brass housing with a press-fit beryllium copper “multi-finger” contact (heat-treated BeCu is the best electrical spring contact material).
