7-16 DIN Female Waterproof Cap Brass

 

FEATURES / BENEFITS
  • Ultra high PIM performance i.e. reduced interference leading to high customer satisfaction
  • Two-piece design i.e. visual inspection of interlocking leads to improved installation security
  • Watertight sealing in mated and unmated condition, i.e. reduced efforts during installation and improved security during operation
  • Tri metal alloy plating i.e. extreme resistance against corrosion even under hardest climatic and environmental circumstances
  • Multi-thread (Tristart) design i.e. simplified and accelerated tightening process

 

 

Difference Between 7-16 DIN And N Connectors：

 

 

 

Physical size:
7-16 DIN: Larger and bulkier, with a wider outer contact (16 mm) and inner contact (7 mm).

N: Smaller and more compact, with a narrower outer contact (10.2 mm) and inner contact (3.6 mm).

 
 

Frequency range:
7-16 DIN: Typically used for lower frequencies up to 7.5 GHz.

N: Can handle higher frequencies up to 11 GHz.

 
 

Power handling:
7-16 DIN: Designed for high-power applications, handling up to 5000 watts.

N: Suitable for both low-power and high-power applications, but generally not as high-power as 7-16 DIN.

 
 

Connection style:
7-16 DIN: Uses a threaded coupling for a secure and reliable connection.

N: Uses a bayonet-style coupling for a quick and easy connection.

 
 

Applications:
7-16 DIN: Commonly found in antenna systems, cellular networks, microwave links, and satellite communications.

N: Widely used in various applications, including WLAN, GPS, radar systems, and general RF transmission.

Size, Density & Torque Compared

One of the biggest differences between these two connectors is physical size and the torque required during installation.

7/16 DIN (L29): Large body diameter (~29 mm), requiring 25–30 N·m torque. Solid, but space-hungry.
4.3-10: Smaller body (~20 mm), torque as low as 5–8 N·m, and optional push-pull coupling that saves time and avoids over-torquing.

Power Handling & PIM Performance

7/16 DIN (L29)
Built for very high power. It can safely manage hundreds of watts, even exceeding 1 kW in broadcast environments.
Its large contact surfaces minimize resistive heating, keeping performance stable during continuous high loads.
PIM performance is typically excellent—around ≤ -155 dBc, provided installation is done with proper torque.

 

4.3-10 Connector
Designed for medium to high power, typical in LTE and 5G systems. While it doesn’t match 7/16 DIN’s extreme capacity, it easily handles the 40–100 W per port typical of modern base stations.
Mechanical stability and optimized inner/outer conductor design give it low PIM performance, often ≤ -160 dBc.
Its lighter torque requirement helps reduce the risk of improper tightening, a common cause of PIM spikes.
