Material & Electrical Characteristics

Environment & Soldering Guide

Product Features

1. Round machined brass female contact, uniform inner diameter, stable contact pressure under vibration & temperature swing
2. PPS high‑temperature plastic housing, H3.0mm low stacking height, UL94V‑0 fire rating, anti‑deformation during soldering
3. Standard 2.54mm pitch, 1*4P single‑row layout, easy PCB footprint design
4. Rated 3A per contact, 600V dielectric voltage, handles mixed signal and low‑power circuits
5. Through‑hole PCB mounting, strong mechanical retention after soldering
6. Customizable contact plating: tin, nickel, flash gold for different corrosion‑resistance demands
7. RoHS / REACH compliant, industrial‑grade mechanical mating cycles ≥500 times

Product Advantage

1. PPS high‑temp housing vs ordinary PA66/PBT: Better anti‑warp performance in wave‑soldering; fewer reject parts during mass assembly
2. DIN‑standard round brass female sockets: More uniform clamping force than stamped contacts; less intermittent signal risk under vibration, suitable for industrial equipment
3. H3.0 mm low‑profile height: saves vertical stacking space for compact embedded PCB modules
4. 600V high‑voltage rating: exceeds common 250V ordinary female headers, supports low‑power auxiliary power‑line connection besides signal transmission
5. Full interoperability: directly mates with off‑the‑shelf 2.54mm male pin headers, no special mating part required, easy BOM sourcing
6. Flexible plating choice: balance cost and anti‑oxidation requirement for consumer, industrial and test‑equipment scenarios

Application

• Industrial control boards, PLC peripheral modules
• Embedded systems, single‑board computers, development & test boards
• IoT gateway, sensor module internal interconnection
• Instrument & measurement equipment
• Power supply auxiliary signal interface
• Automation equipment PCB internal connection
• Medical non‑critical signal modules

Customization Options

1. Confirm pitch strictly as 2.54 mm; verify your PCB footprint before ordering; do not mix‑use with 2.0 mm /1.27 mm pitch parts.
2. Height selection: select H3.0mm when vertical clearance is limited; we support alternative housing height upon request.
3. Distinguish contact type: choose this round female socket if your working environment has vibration; square‑contact female headers are more fit for static consumer‑only scenarios.
4. Plating suggestion:
   • Tin plating: cost‑effective for indoor static consumer products
   • Flash gold plating: preferred for test‑port, frequent plug‑unplug, high‑humidity working environment
5. Electrical limit: do not exceed 3A per pin continuous current; for power‑heavy circuits, upgrade to a higher‑current connector series.
6. Mounting: this model is THT through‑hole type; contact us if you need SMT surface‑mount variant.
