4.0mm pitch waterproof connector application

Part 1: Technical FAQs

Q1: What is the max current rating of A-M4084 waterproof wire-to-wire connector?

A1: Two terminal options are available. Standard copper terminals support up to 15A AC/DC; high-conductivity copper terminals reach 20A AC/DC, with a rated voltage of 600V AC/DC for power transmission.

Q2: What wire gauge and wire insulation diameter does this connector fit?

A2: Compatible wire cross-section ranges from 0.22–1.5 mm² (16–24 AWG). The applicable wire insulation outer diameter is 1.1–2.4 mm, matching most automotive, lighting and energy storage harness wires.

Q3: What waterproof grade and temperature range can this connector withstand?

A3: It achieves IP67 dustproof & waterproof performance to block dust, moisture, rain splash and temporary immersion. Operating temperature covers -40 ℃ ~ +125 ℃, suitable for harsh under-hood, outdoor and high-temperature equipment environments.

Q4: What cavity layouts are available for the M4084 series?

A4: Single-row versions support 2/3/4/5 positions; dual-row versions provide 6/8/10 positions. Both male plug housing (A-M4084M) and female receptacle housing (A-P4084F) adopt the same layout specifications.

Q5: What materials are used for housing and terminals, and are they automotive-certified?

A5: The housing is made of PA material; terminals are pure copper. All models carry automotive certification marked with the prefix "A" in part numbers, stable for long-term vibration and thermal cycling.

Q6: How does the sealing structure guarantee reliable waterproof performance?

A6: Waterproof seals, copper terminals, PA housing and single-wire waterproof plugs are structurally matched as a whole. Coordinated assembly design improves installation efficiency and long-term sealing stability without water ingress risk after full mating.

Part 2: Purchasing FAQs

Q1: Where can I download the official datasheet of A-M4084 series connector?

A1: Please send an inquiry to our sales team, and we will provide the complete datasheet including part number definition, dimensional drawings, electrical parameters and assembly exploded views for your project evaluation.

Q2: What color options are available for the M4084 housing?

A2: Standard housing color is white (marked "W" at the end of PN). Custom housing colors can be developed upon your mass order demand.

Q3: Can I get samples of male and female housings plus matched terminals for testing?

A3: Yes, we support sample provision for verification. If all items are out of stock, we will arrange dedicated machine production and quote a one-time sample cost with sample lead time of 2–3 weeks.

Q4: What is the HS code of this 4.0mm waterproof wire-to-wire power connector?

A4: The unified HS code for the A-M4084 series is 8536909000, applicable for export customs declaration globally.

Q5: What industries and applications are this connector widely used for?

A5: Ideal for new energy vehicles, two-wheelers, lithium energy storage, outdoor LED lighting, power tools, industrial control, PV storage and mid-to-high-end smart home appliances with IP67 power connection demands.

Q6: What is the standard lead time for mass production orders?

A6: Standard in-stock items can be shipped within 5–7 working days. For out-of-stock models requiring production runs, the mass lead time will be confirmed separately after receiving your order quantity.
