D38999/26FB35SN Industrial Circular Connector | Bayonet Multi-Pin Signal Plug

Product pictures

This product photo displays the male and female paired terminals of D38999/26FB35SN circular industrial connector. The contact cavity adopts blue and black insulating plastic for clear distinction between two mating ends, with all pin positions printed with serial numbers for convenient wiring alignment. The shell is made of matte metal with knurled outer surface, which improves hand friction for easy manual plugging and unlocking. The built-in sealing ring structure can fit tightly after docking. The whole component has precise hole position layout, stable insulating structure, and neat mechanical workmanship, which allows buyers to quickly confirm pin count, arrangement mode, locking structure and insulation configuration.

Product overview

D38999/26FB35SN is a high-reliability multi-pin bayonet circular connector developed for industrial multi-circuit signal and low-current power connection. It features all-metal shielding housing to block external electromagnetic signal interference effectively and guarantee stable circuit transmission. The insulating insert is resistant to high temperature and burnout, adapting to long-term continuous power-on work. The bayonet quick-lock design realizes fast plug-in positioning and anti-loosening during vibration. With complete sealing performance, the connector can resist splashing water, dust and moist air erosion. Widely matched with intelligent automation equipment, laboratory testing instruments, industrial communication cabinets, new energy control modules and factory automated production lines. Every connector undergoes strict continuity, insulation and aging tests before delivery. We support customized finished cable assembly according to client wiring needs for global industrial matching.

Workshop

Our factory builds specialized production zones classified by metal processing, plastic molding, contact assembly and finished testing for industrial circular connectors. CNC lathes process connector metal shells with precise dimensional tolerance; high-temperature injection molding equipment produces insulated inserts with stable density. The assembly workshop adopts dust-free operation environment to avoid dust contamination of pins and insulating parts. Multiple offline testing stations carry out high-voltage withstand test, vibration fatigue test, waterproof immersion test and salt spray corrosion test. All production steps follow unified SOP management. Stable mass output capacity supports repeated bulk orders from overseas customers, with adjustable production schedule to match different delivery deadlines.

Exhibition

We participate in global professional expos covering industrial electronics, automation accessories, measuring equipment accessories and wiring accessories every year. On-site display includes full series of D38999 style circular connectors, terminal samples and pre-assembled cables. Professional technical sales communicate with system integrators, equipment manufacturers and purchasing merchants to sort out matching schemes according to equipment voltage, pin quantity and installation environment. We keep updating product specifications according to market demand collected from exhibitions. Long-term stable cooperation is established with many overseas clients relying on stable quality and flexible personalized supporting solutions.

Package

Single D38999/26FB35SN connector is wrapped with soft anti-scratch foam cotton to prevent surface metal scratch during transportation. Each piece is separately placed into small antistatic plastic box to avoid static damage to internal contacts. Quantified products are sorted and packed into thickened five-layer export cartons, with product model, quantity and shipping information clearly marked outside. Multiple international shipping options including express delivery, air freight and ocean shipping are available. Cartons are reinforced with strapping tapes, featuring compression resistance and shock resistance to ensure intact arrival of connectors to overseas warehouses.
