ST352 - RCA Plug

The ST352 is a precision metal plug connector from Seetronic, designed for reliable, repeatable connections in demanding environments. Its rugged zinc diecast shell and knurled grip provide a durable, easy-to-handle housing, while brass contacts ensure consistent, low-resistance performance over more than 1,000 mating cycles.

Key Features

• Compact Precision Housing: Ø12.00±0.20mm diameter and 46.50±0.30mm overall length in a zinc diecast metal shell for a slim, rugged profile.
• High Mating Cycle Durability: Rated for over 1,000 mating cycles, supporting frequent connect/disconnect use without performance loss.
• Strong Dielectric Performance: Withstands 1500V DC dielectric strength testing with insulation resistance greater than 5GΩ, ensuring safe electrical isolation.
• Flexible Cable Compatibility: Accommodates 16AWG signal wire and cable outer diameters from 3.5mm to 6.5mm for broad application coverage.
• Knurled Grip Design: Textured cable-entry section improves handling and grip during installation and removal.

Material and Environmental Specifications

• Shell Material: Zinc diecast construction for mechanical strength and durability.
• Contact Plating: Tin (Sn) surface finish for corrosion resistance and stable conductivity.
• Flame Retardant Rating: UL94-HB rated for baseline flame-retardant performance.
• Operating Temperature Range: -30°C to +80°C, suitable for a wide range of climates and indoor industrial conditions.
• Ingress Protection: IP40 rated, protecting against solid objects larger than 1mm; not designed for water exposure.
• Electroplating Standard: Manufactured to IEC 68-2-20 electroplating compliance standards.

Assembly Instructions

• Prepare the Cable: Strip the cable jacket and prepare the 16AWG signal conductor(s), ensuring the cable outer diameter falls within the 3.5-6.5mm compatible range.
• Insert Through the Shell: Feed the prepared cable through the rear shell and cable clamp section of the connector body before terminating the conductors.
• Terminate the Contacts: Connect the signal wire to the internal brass contact pin per the wiring configuration required for your application.
• Seat the Contact Assembly: Insert the terminated contact assembly into the connector housing until fully seated and secure.
• Secure the Cable Clamp: Tighten the rear cable clamp/coupling nut to secure the cable in place and provide strain relief.
• Final Inspection: Verify the assembled plug is fully seated, that the knurled grip section is properly aligned, and that the connector mates smoothly with its corresponding socket.
