Overview
The 7/16 DIN connector is a threaded RF connector widely used in high-power,Gold plated contacts enhance conductivity 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 Patient monitoring systems with wireless connectivity,RF ablation, telemetry, and diagnostic tools,MRI, CT, and ultrasound imaging devices 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)

Military connectors: 100 PCS
What is the difference between RF connectors and coaxial connectors?
They are often used interchangeably. However: Coaxial connector refers to the physical design (shielded cylindrical form). RF connector emphasizes its use in radio-frequency applications. Most RF connectors are coaxial.
What is “reverse polarity” (RP-SMA, RP-TNC)?
Reverse polarity means the gender of the center pin is swapped while keeping the outer body style unchanged. It was introduced to comply with regulatory requirements in Wi-Fi devices and to prevent connection with standard SMA/TNC.
What’s the lifespan of an RF connector?
Connector durability is rated in mating cycles: General-purpose connectors (BNC, SMA): 500 cycles. Precision connectors (2.92 mm, 2.4 mm): 500 cycles or less. Rugged telecom connectors (N, 7/16 DIN): 500 cycles.
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.
