Overview
The 7/16 DIN connector is a threaded RF connector widely used in high-power, and low-PIM (Passive Intermodulation) applications. Its name comes from the dimensions of the inner and outer contacts: 7 mm (outer conductor) and 16 mm (inner conductor). Designed originally in Europe, it has become an industry standard for Cable TV distribution and headend systems,Vehicle radar (24 GHz, 77 GHz for ADAS),Studio equipment, satellite uplink/downlink stations and other demanding RF installations.
Features
| High Power Handling | Supports up to several kilowatts of power, thanks to its robust design and low contact resistance. |
| Low PIM Performance | Typically -150 dBc or better, making it ideal for cellular base stations and DAS (Distributed Antenna Systems). |
| Rugged Mechanical Design | Large, threaded coupling ensures secure, vibration-resistant connections. |
| Weatherproof Options | Often available with gaskets or weather seals for outdoor use. |
| Durability | Can withstand repeated mating cycles (>500) |

FAQ
Sample Delivery Time
Regular models require 15 days, while some complex connectors require 25 days.
Sample Fee
Most RF connectors are CNC-machined parts and do not require mold-making.
However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.
This fee will be refunded after a 5K bulk order.
Guarantee
Brass RF connectors come with a one-year warranty.
Stainless steel connectors come with a three-year warranty.
The lifespan also depends on the contact material beryllium contacts offer better durability.

What is impedance, and why is 50 Ω or 75 Ω important?
Impedance matching prevents signal reflection and power loss. 50 Ω: Standard for RF communication, test equipment, aerospace, defense. 75 Ω: Standard for broadcast, video, and cable TV applications.
What materials are RF connectors made of?
Body: Brass, stainless steel, or beryllium copper (with nickel, gold, or silver plating). Insulator: PTFE, PE, or advanced low-loss dielectrics. Contacts: Gold-plated brass or beryllium copper for low resistance and durability.
Are RF connectors weatherproof?
Some RF connectors are designed with gaskets and sealing (e.g., N-type, 4.3-10) for outdoor telecom, antennas, and harsh environments. Indoor lab connectors (e.g., SMA, BNC) are usually not weatherproof unless specified.
What’s the difference between male and female RF connectors?
Male: Has a center pin and usually an outer thread or bayonet. Female: Has a receptacle (socket) for the center pin and matching thread. Some connectors (like SMA) can be confusing because “reverse polarity” (RP-SMA) swaps pin/socket configuration.
Materials
