M55-6025042R

Headers, Receptacles, Female Sockets Overview

The Harwin M55-6025042R is a 50-position surface mount receptacle connector from the Kontrol M55 series. It features a 1.27mm (0.050 inch) pitch with two rows of female phosphor bronze contacts. The housing is constructed from black liquid crystal polymer (LCP) rated UL94 V-0, with an insulation height of 13.64mm. Contacts are gold-plated for mating surfaces and tin-plated for soldering. Rated for 100VAC and 1.2A, it operates within -55°C to 125°C. Key mechanical features include board rails, pick-and-place compatibility, and solder retention.

Headers, Receptacles, Female Sockets Feature Summary

• Integrated board rails facilitate automated pick-and-place assembly and ensure precise solder retention during reflow processes.
• Locking post design provides secure mechanical fastening between mated boards to maintain connection integrity under vibration.
• Vertical surface mount configuration allows for compact board-to-board stacking with controlled standoff heights.

Headers, Receptacles, Female Sockets Applications

• Automotive electronic control units
• Industrial automation systems
• General purpose PCB interconnections

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and packaging format. Confirm that the selected variant aligns with the intended thermal profile for lead-free assembly processes. Ensure that the locking post mechanism is compatible with the mating header's engagement style. Cross-reference the insulation material specifications against environmental exposure requirements in the final application environment.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile vertical interconnect is required for high-density signal routing. The 1.27mm pitch balances spacing constraints with current carrying capacity needs. Consider the LCP housing properties for applications requiring high thermal stability and chemical resistance. Evaluate the available stacking heights to determine if the standard or extended versions better suit the mechanical envelope constraints of the assembly.
