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.

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 is 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.
