Overview
The 7/16 DIN connector is a threaded RF connector widely used in high-power,Reliable 50 Ω impedance matching 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 MRI, CT, and ultrasound imaging devices,Patient monitoring systems with wireless connectivity,Railway communications and signaling systems 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.
ROHS & REACH Compliance
Our products fully comply with ROHS & REACH regulations.
Does LENORF Offer Military-Grade Products?
Yes. We are honored to provide military-grade products with exceptionally stable quality.
MOQ (Minimum Order Quantity)
Regular connectors: 500 PCS
Adapters: 100 PCS
Military connectors: 100 PCS
Can RF connectors be reused?
Yes, but performance degrades with wear. Precision connectors (used in test equipment) should be handled carefully—damage to threads or pins increases VSWR and insertion loss.
What’s the difference between threaded, bayonet, and push-on RF connectors?
Threaded (SMA, N, TNC): Secure, vibration-resistant. Bayonet (BNC): Quick connect/disconnect. Push-on (MCX, SMP): Ultra-fast, compact, used in high-density modules.
Are RF connectors interchangeable between brands?
Yes, if they follow the same standard (e.g., SMA-to-SMA). However, tolerances, plating, and dielectric quality vary — mixing low-quality and precision connectors can damage equipment.
How do environmental conditions affect RF connectors?
Temperature extremes can cause expansion/shrinkage and change performance. Humidity and salt spray may cause corrosion (use stainless steel or weatherproof designs). Vibration may loosen bayonet types — use threaded connectors in harsh environments.
