Product Engineering Drawing

Core Configuration Diagram

Dimensional Drawing

The dimensional drawing provides key mechanical data per attached CAD extract. Male plug overall length 43.7mm, with mating thread length 14.6mm and panel-side thread 12.0mm; cable entry accepts up to 6.0mm OD. Female receptacle overall length 43.3mm, featuring thread depth 15.4mm on mating face and 8.5mm on mounting side – note the asymmetry between male/female engagement lengths. The fully mated assembly reduces to the specified envelope. All threads are M12×1.0; tolerances per ISO 2768-m. Polarising key position is marked to ensure correct orientation. PDF/DWG available for CAD integration. Verify the 14.6mm and 15.4mm engagement depths when calculating panel clearance and thread overlap.

Product detail

Male Plug Front View (3-Pin, Black PVC Housing)

This front-face view shows the male plug with three nickel-plated brass contacts arranged in the standard M12 circular pattern (1.0 mm diameter pins). The black PVC moulded housing provides mechanical protection and electrical insulation; the integral polarising key is visible at the 12 o'clock position, ensuring correct orientation during mating. The flush face design allows easy cleaning of debris before connection. No sealing ring is exposed on this side – it resides behind the thread root. Use this image to verify pin condition, centering, and the absence of burrs or deformation prior to assembly.

Male and Female Separated (Red Circle Highlight)

This photo shows the male plug (left) and female receptacle (right) separated, with a red circle highlighting the sealing O-ring on the male thread root – the primary IP67 sealing element. Both metal threads (M12×1.0) are fully visible; the red callout aids in locating the seal before assembly, preventing omission during field installation. The O-ring material is rubber, compatible with –20°C to +85°C and resistant to moisture and mild chemicals. This image serves as a visual reminder to inspect the O-ring for cuts or wear before each mating.

FAQ

Q1: How many mating cycles can your connectors handle?

A: Rated at 1,500 mating cycles. If you're working with test equipment, portable instruments, or any application that requires frequent plugging and unplugging, this lifespan ensures long-term reliability.

Q2: Are you a factory or a trading company?

A: We are a manufacturing enterprise with our own production facilities and quality control team. We specialize in waterproof connectors, adapters, power connectors, and custom wiring harnesses – everything from raw materials to finished goods is under our direct control.
