The connector features a dark olive-green metal housing, a circular mating interface, four gold male pin contacts, and an operation area with knurled texture. Its snap-fit connection mechanism achieves locking through a specified rotational action, making it suitable for connection scenarios requiring regular disassembly and reassembly, equipment maintenance, or harness replacement.
The product is equipped with a chain-type protective cap, which can be used to protect the interface when the connector is not in use, reducing the risk of dust and foreign objects entering, and lowering the likelihood of the protective cap being lost. The vertical plug layout is suitable for conventional cable pulling and harness assembly, and can be used for internal electrical connections of equipment, control cabinet wiring, and industrial system interface design.

Product Features
- Four-Pin Male Contact Arrangement
The connector features four male pin contacts, providing four independent electrical connection positions within a single circular interface.
- Size 12 Shell Configuration
The MS3116R-12-4P part number identifies a size 12 shell configuration. Shell size is an important mechanical selection parameter and must be checked against the mating interface, available installation space, and coupling geometry.
- Bayonet Coupling Mechanism
The connector uses a bayonet coupling mechanism that combines mechanical alignment with rotational locking. This design supports controlled mating and unmating for equipment requiring periodic maintenance, circuit inspection, or component replacement.
Key Performance Advantages
◆ Consolidated Multi-Circuit Connectivity
The four-contact arrangement consolidates multiple electrical connection points into one interface, reducing the need for separate connectors for individual circuits. For control modules, inspection equipment, and compact industrial devices, this layout helps standardize interfaces, organize wiring sequences, and simplify harness management.
◆ Convenient Servicing and Component Replacement
The bayonet coupling is suitable for equipment that requires periodic disconnection and reconnection. Following the prescribed locking and release procedures allows technicians to inspect circuits, service components, and replace harnesses without relying exclusively on permanent wiring arrangements.
Product FAQ
Can the MS3116R-12-4P Directly Replace Other Four-Pin Circular Connectors ?
Matching contact counts alone do not establish interchangeability. Verify the shell size, insert arrangement, keying, bayonet geometry, termination method, and electrical ratings. For repairs or equipment upgrades, compare drawings and perform a sample fit check first.
Is the MS3116R-12-4P Suitable for Internal Wiring or External Cable Connections ?
This straight circular plug can provide a detachable electrical connection between an equipment harness and a compatible connector. Whether it is used for internal wiring or an external cable interface depends on the equipment layout, cable routing, available space, and operating environment.
What Should Be Checked Besides the Four-Contact Configuration When Selecting a Mating Receptacle ?
In addition to the four-contact configuration, verify shell size, insert arrangement, polarization keys, bayonet coupling geometry, contact type, and relevant electrical ratings. Connectors with the same contact count may still be incompatible because of different mechanical keying or interface dimensions.
Does Premier Cable Offer Wholesale and OEM Services ?
Premier Cable can evaluate connector integration, custom cable assemblies, OEM manufacturing, and volume procurement according to project requirements.
