The DC5525 female connector adopts a standard specification of 5.5mm outer diameter and 2.5mm inner diameter. It can accurately mate with male connectors of the same specification and is also compatible with DC5521 male connectors (long-term mixed use is not recommended). The connector housing is made of flame-retardant ABS plastic, and the internal terminals.
The DB9 female-to-female connector shielded cable assembly is a type of connecting cable with DB9 female connectors at both ends, which is mainly used for signal transmission between serial port devices and reduces electromagnetic interference via its shielding layer. Two common types of shielding layers are available: aluminum foil shielding (AL) and aluminum foil shielding combined with tinned copper braid (AL+Braid). Aluminum foil shielding can basically meet general anti-interference requirements, while the double-shielded structure of aluminum foil plus tinned copper braid offers superior EMI (Electromagnetic Interference) performance.
The DB9 male-to-female connector shielded wire harness is a type of cable used to connect devices with DB9 interfaces, playing a vital role in ensuring the stability of signal transmission. One end is a DB9 male connector and the other is a DB9 female connector. The male connector is equipped with 9 pins while the female one has 9 sockets, which are designed for connection with the DB9 interfaces of devices. It generally adopts a double-layer shielding structure of aluminum foil or aluminum foil combined with tinned copper braid, which can effectively block external electromagnetic interference and prevent internal signals from radiating outward, thus ensuring the accuracy of signal transmission.
The shielded wire harness for DB9 male-to-male connectors is a dedicated cable assembly developed on the basis of standard DB9 male-to-male connection cables, with an additional shielding layer structure. Its core function is to suppress electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring stable serial data transmission, and it is especially suitable for complex electromagnetic environments. The conductor is mainly made of oxygen-free copper (OFC) or tinned oxygen-free copper: oxygen-free copper has high purity (≥99.95%), excellent electrical conductivity and low resistance, which can reduce signal attenuation during transmission and is ideal for medium and long-distance serial communication; tin-plating treatment enhances oxidation and corrosion resistance, extends the service life of the wire harness, and improves soldering stability.
This is a DC power connection cable composed of a DC5521 connector and UL2464-certified 18AWG 2-core wire. It features high current-carrying capacity and safety compliance, making it ideal for power supply scenarios of medium-to-high power DC equipment. The DC5521 connector is a commonly used DC power interface with dimensions of 5.5mm outer diameter and 2.1mm inner diameter. It enables smooth plugging and unplugging with excellent locking performance, and is widely compatible with power female sockets of LED strips, surveillance cameras, and small industrial control equipment.
The AM1015B T-type terminal connector silicone wire harness is a harness commonly used for high-current connections and is widely applied in electric smart scooters, lithium batteries, and other fields. The AM1015B terminal connector typically uses PA (polyamide) as the insulating material, which provides good insulation performance and mechanical strength. Its metal parts are made of gold-plated copper, which can effectively reduce contact resistance and improve conductivity and corrosion resistance.
