Question-led planner

2 pin auto waterproof connector choices still open

Use this planner when a 2 pin auto waterproof connector is the line you need to price, and several mechanical choices are still blank. LinkScope Sourcing 38 lists the blanks. It does not assign a vehicle platform or a current rating you have not written.

Two-position sealed connector, wire seals, and a blank pin table
  1. Latch or CPA present, missing, or unknown
  2. Wire gauge and whether both pins use the same size
  3. System voltage, often 12 V or 24 V, plus the current each pin must carry
  4. Seal condition: mated only, or also capped while unmated

Evidence ledger for a two-position sealed part

What to request before accepting a 2-pin alternative
Row Ask the plant to attach Reject as proof
Identity Manufacturer, model, gender, and drawing revision for the 2-pin housing A photo of a similar latch on a 4-pin body
Contacts Current in amperes, voltage, plating thickness, and termination (crimp size or PCB) Jacket color or a marketing sentence about durability
Seal IP code, mated state, depth, duration, and temperature window such as -40 C to 125 C if the drawing uses that window A statement that the part is waterproof with no method
Mate Keying, pitch if stated, and the mating half the drawing names A claim that any 2-pin auto housing intermates

If this line sits on a radio tail, add impedance, frequency range, and VSWR for the finished lead. Insertion loss and return loss then belong to that lead, not to the housing family. A power-only 2-pin seal has no optical budget and no MIMO figure.

Compatibility questions before you accept a substitute

Does the latch match the mating half already on the harness?

A compatible shell can widen supply when the pin map, seal diameter, and keying match the half you already own. An original housing can be simpler when the drawing names one model. Write which half is fixed before you invite alternatives.

Is the contact new, or is the body from surplus stock?

New contacts make plating and date code easier to read. A surplus body may fit a legacy latch if seal elasticity and remaining mating cycles are stated. Do not mix those stories in one price cell.

What fails if the pin current is higher than the contact size?

A 2-pin housing can be asked to carry a lamp, a sensor, or a small fan. The contact, not the plastic shell, sets the ampere limit. Ask for the temperature at which that ampere figure was taken. Leave the cell blank if the plant will not state it.

Limits on this planner

  • Two pins do not imply IP67 or IP68. IEC 60529 still needs a mated-sample statement. IP67 is often cited as 1 m for 30 minutes. IP68 needs the plant depth and time.
  • A mating-cycle count of 100 or 500 without current and plating thickness cannot be compared. Gold at 0.76 micrometres is not flash gold.
  • This page has no file upload. Paste the two pin rows into the requirement box. Drawings follow after the first reply.
  • The desk does not road-test, salt-spray, or certify the latch. Your incoming check remains yours.

Paste the two-pin line into the brief

Write pin 1 and pin 2 as separate sentences: wire gauge, seal, and current. Add quantity, US destination, and timing. Optional budget needs currency and a per-piece or whole-order basis. There is no upload control on this form.
