The material of a DIP switch significantly impacts its performance, primarily through mechanical properties, electrical characteristics, and chemical stability.

KH-GPSBD5056SMA-3M GNSS Antenna 1.Excellent Interference Resistance: Utilizes advanced GNSS technology to efficiently capture and transmit positioning signals, even in weak or interference-prone locations. It’s highly effective in densely populated urban areas or industrial zones with strong electromagnetic interferenc……

Transmission Principle: When transmitting a signal, high-frequency current from the signal source is fed into the radiating element of the magnetic mount antenna. According to the principle of electromagnetic induction, the varying current generates a changing magnetic field around the antenna, which in turn creates a ……

Smartphones: Used for power, volume control, and mute switches. Their small size makes them ideal for the compact internal space of phones, offering reliable performance and good tactile feedback for frequent use.

​The lifespan of Kinghelm GPS antennas is not fixed but typically lasts around 6-7 years. For example, the KH-GPS/BD5056SMA-3M is a highly durable antenna that ……

Kinghelm KH-MICRO-SMT.MK-5P: This is a Micro-B connector compliant with the USB 2.0 standard, with a mating cycle life of up to 10,000 insertions.

Kinghelm's Bluetooth antennas are generally compatible with the standard Bluetooth protocol framework, supporting common protocols such as HSP (Headset Profile), HFP (Hands-Free Profile), A2DP (Advanced Audio Distribution Profile), and AVRCP (Audio/Video Remote Control Profile).

Antenna Gain: Gain measures the antenna's ability to amplify the signal, typically expressed in dBi. Higher gain usually results in a greater signal range and coverage area. The KH0WF-02-J3 antenna, with a 3dBi gain, offers medium-range performance in its category.

The production lead time for Kinghelm's customized antennas varies depending on several factors. For specialized or non-standard products, the delivery timeline will be determined by the sales representative and the engineering department.
