A2 Series Beijing-Pattern 2+8 Plug-in Connector
The A2 Series Beijing-Pattern 2+8 connector — the plug half of the A2 interface — is supplied in black / white. The A2 keeps the twist-lock knob of the A series but follows the Beijing-pattern pin layout: two power contacts plus an eight-pin signal block. Because the footprint matches the common domestic standard, it drops into existing housings without a redesign.
- Matched plug-in connector for machines built to the Beijing-market 2+8 interface
- Keyed shell — mates one way only, no reversed insertion
- 2 power + 8 signal carried in a single mated pair
- Black / White housing; flexible or rigid hose
- OEM colour, logo and pin-out options on request

Overview
The A2 Series Beijing-Pattern 2+8 connector — the plug half of the A2 interface — is supplied in black / white. The A2 keeps the twist-lock knob of the A series but follows the Beijing-pattern pin layout: two power contacts plus an eight-pin signal block. Because the footprint matches the common domestic standard, it drops into existing housings without a redesign.
It is used on machines built to the Beijing-market 2+8 interface, a de-facto standard on many Chinese-made beauty platforms. The 2+8 arrangement separates high-current handpiece power from low-level control and sensor lines, which keeps signal noise away from the power path. It is the part most often requested as a drop-in replacement when a machine is exported or a second source is needed.
Order it together with its mating half — A2 plugs and handpiece-end connectors are sold as a matched pair, so keying and pin-out always line up.

Frequently asked questions
Which machines does this connector fit?
It is designed for machines built to the Beijing-market 2+8 interface, a de-facto standard on many Chinese-made beauty platforms. Interface compatibility depends on the pin-out and keying of your handpiece, so send us a photo of the mating socket or the machine model before ordering; we will confirm the match in writing.
Is this a complete connector or half of a pair?
This listing is the plug half. The mating handpiece-end half is a separate part number; order both for a guaranteed keyed pair.
Can you supply samples before a bulk order?
Yes. Samples are available for evaluation, and the sample cost is normally credited against the first production order.
Can the colour, logo or pin-out be customised?
Housing colour and laser marking are tooling-dependent and can be quoted; pin-out changes require a minimum quantity because they change the contact block.
What is the MOQ and lead time?
Both depend on the series and configuration. Send your annual volume and target date and we will return a firm quotation with a production schedule.
