This jack cable is used for connecting audio equipment with a 2.5 mm audio jack. The cable transmits analog audio signals between devices such as smartphones, headsets, audio equipment, amplifiers, and other devices with a 2.5 mm jack connection. The cable features 2.5 mm male jack connectors on both ends and supports stereo audio. This allows two audio signals to be sent via a single cable, for example, a left and a right channel. The cable can be used for connecting various multimedia and audio devices. The flat cable construction ensures a small bending radius and makes the cable flexible during use. The connectors are equipped with nickel-plated contacts that ensure a stable electrical connection between the connected devices. Specifications Cable type: jack audio cable Audio type: analog audio connection Connector 1: 2.5 mm jack male Connector 2: 2.5 mm jack male Connector type: TRS Mono / stereo: stereo Contact material: nickel-plated Cable type: flat cable Color: black Certifications: CE, WEEE Explanation 2.5 mm jack: a compact audio connector used in headsets, communication equipment, walkie-talkies, and other compact electronic devices. This connection is used less frequently than 3.5 mm or 6.3 mm jack connections. TRS connector: a jack connector with three contacts (Tip, Ring, and Sleeve). This allows two audio signals to be transmitted, enabling stereo audio. Flat cable: a cable construction where the conductors lie side-by-side in a flat jacket. This gives the cable a small bending radius and allows it to be easily concealed. Nickel-plated contacts: a metal contact layer of nickel that ensures a stable electrical connection and protects the contact surface. Applications • Connection between devices with a 2.5 mm audio jack • Connecting headsets and communication equipment • Connection between multimedia devices and audio equipment • Use with portable audio devices and accessories Types of jack connectors 6.3 mm jack: a larger jack connector primarily used with professional audio equipment, musical instruments, mixers, and studio installations. 3.5 mm jack: a smaller jack connector widely used in consumer electronics such as smartphones, laptops, tablets, and portable audio devices. 2.5 mm jack: a compact jack connector used in headsets, walkie-talkies, and specialized audio equipment. Explanation of jack configurations TS (Tip-Sleeve): a jack configuration with two contact points. The tip transmits the audio signal and the sleeve acts as ground. This configuration is used for mono audio signals. TRS (Tip-Ring-Sleeve): a jack configuration with three contact points. This allows two audio signals to be transmitted, for example, a left and a right channel for stereo audio. TRS can also be used for balanced audio signals in professional audio equipment. TRRS (Tip-Ring-Ring-Sleeve): a jack configuration with four contact points. This type of connection allows a microphone signal to be transmitted in addition to stereo audio via the same connector, for example, in headsets. Explanation of audio signals Balanced audio: a method for audio transmission using two signal wires and a ground. Interference picked up along the way is cancelled at the receiver, resulting in a more stable audio signal with less noise. Unbalanced audio: a form of audio transmission using one signal wire and one ground wire. This type of connection is widely used in consumer equipment such as smartphones, laptops, and Hi-Fi systems. Stereo audio: an audio system that uses two separate channels: a left channel and a right channel. This creates a spatial sound image. Mono audio: an audio system that uses only one audio channel and sends the same signal to all speakers. Ask a product question
