Description
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.
Packaging and Accessories
• Standard Unit Packaging : Individual plugs are packed to prevent scratching of the shell finish and contact damage during transit (please confirm exact carton/tray specifications with your sales contact, as these are configured per order).
• Custom Branding Available : The connector body accommodates the Seetronic logo mark as shown; OEM/custom branding options may be available on request.
• Order-Specific Configuration : Cable length, connector color, and accessory bundling (e.g., matching sockets) can be configured to customer specification — please contact Seetronic for a tailored quotation.
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.
