It has that trusted scoop-proof shell. This simple design stops contact pins from bending when technicians plug in at an angle, a common headache out on site. Its strong alloy housing shields inner contacts. Silicone seals fitted inside ke ep dust and moisture out, so connections stay reliable through long run times.
This receptacle works with mixed power and signal contact layouts. Matching M39029 contacts ship separately, plus pin extraction tools included. The hand tools let technicians swap pins quickly while wiring on location. The shell plating resists corrosion well for long service in harsh surroundings.
Once assembly wraps up, every single D38999/20WB04SA goes through separate QA checks. Our team looks over surface finish, dimensions, sealing and electrical continuity. Any bad units get discarded before packing. We stock common variants for quick dispatch, and we can handle minor tweaks to fit your project needs.
Drop us a message if you need full technical info before you commit. We can send datasheets, pin diagrams and physical samples. Your engineering group can run lab evaluations and validate performance prior to bulk purchase.
Why choosing us?
We own a full set of mature molds for insulator and silicone rubber parts. These molds are always ready for mass production, so we can kick off bulk manufacturing quickly whenever orders come in.
