Key Product Advantages
50-Position Female Interface
The 50 pin female circular connector combines 50 contact positions in one compact interface for industrial control, instrumentation and multi-conductor equipment wiring.
Threaded Cable Connection
The threaded coupling structure helps the PC-50T circular cable plug maintain a secure mechanical connection with a compatible PC Series equipment-side receptacle.
Flexible Solder Cup Wiring
Solder cup contacts support 22–28 AWG conductors, making the PC Series 50 pin connector suitable for customized pin assignments and OEM cable assemblies.
50-Pin Female Contact Layout

The PC-50T 50 pin female circular connector uses a high-density 50-position female contact arrangement within a keyed circular interface. This configuration allows multiple control, signal or low-current circuits to be combined into one detachable connection.
The 50 pin threaded circular connector is particularly useful in industrial controllers, measurement instruments, test equipment and machinery requiring numerous electrical connections through one compact cable interface.
For replacement or OEM cable assemblies, the contact numbering and pin assignment should always be confirmed against the equipment wiring diagram before production.
Mating & Compatibility
PC-50T Female Cable Plug + Compatible Male Panel Receptacle
The PC-50T female threaded circular cable plug is designed for cable-side installation and requires a mechanically compatible PC Series 50-position male receptacle on the equipment side. The threaded interface provides a detachable connection between the external cable assembly and equipment.
| Connection Side | Connector Configuration |
| Cable Side | PC-50T – 50-Pin Female Threaded Cable Plug |
| Equipment Side | Compatible 50-Pin Male PC Series Receptacle |
For a PC-50T mating connector or replacement cable assembly, thread dimensions, keying, contact arrangement and wiring should be verified before ordering. Premier Cable can manufacture customized mating cable assemblies according to customer drawings and equipment wiring requirements.
