HRB 3.0mm Pitch Latch‑Lock Waterproof Wire‑to‑Wire Electrical Connector

HRB compact 3.0 mm pitch latch‑lock wire‑to‑wire waterproof connectors deliver IP67 protection (IEC 60529) for free‑hanging cable‑side applications. Built with PBT UL94 V‑0 housing, silicone seals and tin‑plated phosphor‑bronze contacts, they carry 10A / 250V across ‑40 ℃ ~ +105 ℃. The integrated TPA secondary lock guards against terminal back‑out under vibration. Compatible with AWG 18‑22 cables in 2‑6‑pin single‑/dual‑row layouts, they meet RoHS & REACH requirements for outdoor equipment, industrial motors, agricultural drones, spotlights and mobility devices.

Technical FAQs


Q: What is the recommended wire strip length?

A: Reference value for wire strip length is 3.00±0.20mm.

The wire strip length depends on wire type and crimping method, and actual processing conditions shall be used to confirm the optimal strip length.

Do not nick or cut wire conductors during wire‑stripping operation.


Q: How to insert crimped terminal into housing correctly?

A: Before inserting the crimped terminal, align the orientation of housing and terminal for proper mating.

When the lock opening of the housing faces upward, the barrel‑seam side of the crimped terminal shall also face upward.

Do not rotate the terminal during or after insertion. Rotation may cause damage to rubber seals and housing.

Note: For terminal insertion: keep the smooth surface upward, anti‑key feature downward, and terminal barrel seam upward. Incorrect orientation will cause housing damage.


Q:What is the wiring recommendation for harness exiting from the connector?

A:Avoid sharp 90‑degree bends immediately at the connector wire exit. Sharp right‑angle bending will shorten harness service life and may lead to functional failures. Gradual, gentle cable bending is recommended during routing design.


Q:What should be noted during finished‑product inspection of harness assemblies?

A:

1. Use precision fixtures during wire inspection and electrical continuity testing to avoid prying the connector.

2. Perform continuity tests using the mating counterpart connector (e.g. receptacle for tab contact). Do not use non‑matching test 

pins. Replace test mating connectors periodically.

3. Replace any deformed or damaged connectors, contacts, sealing rings or wire seals with new parts directly, regardless of damage 

severity. Do not attempt repairs.

4. Verify wire seals are properly seated inside the housing.

5. Do not perform air‑blow testing, as this may dislodge sealing components.


Q:What are the storage and transportation precautions for connectors and harnesses?

A:

1. Store housings and crimped contacts under conditions: temperature 25 °C ± 5 °C, relative humidity ≤70% RH. Keep away from 

direct sunlight, moisture and dust. Sealing rings and wire seals are rubber‑based components. UV exposure will cause rubber aging, 

and dust contamination will degrade waterproof performance.

2. Handle stacked housings and wire harnesses with extra care during storage and transportation.


Q: What are the functions of latch‑lock female housing and panel‑mount female housing?


⒈Latch‑lock female housing (cable‑end)

Free‑hanging cable‑mount housing without panel mounting lugs. It locks to mating male housing via built‑in latch.

Function: Crimped onto cable ends for wire‑to‑wire connection. It moves together with wiring harness, not fixed to equipment 

chassis. Ideal for internal wiring, cable assemblies and peripheral extension cables.


⒉Panel‑mount female housing (equipment‑end)

Comes with mounting lugs, secured to equipment enclosure cut‑out by M4 bolts.

Function: Acts as a fixed external interface on device panel. It stays firmly mounted on chassis, accepting mating cable‑side plug. 

It provides sealing separation between inside and outside of equipment. Widely used for cabinet, motor housing and drone body 

ports.
