This DELOCK jack cable is used for connecting audio equipment with a 3.5 mm audio jack. The cable transmits analog audio signals between devices such as smartphones, tablets, headsets, car radios, amplifiers, and Hi-Fi systems via a combined audio and microphone connection. The cable features 3.5 mm male jack connectors with a 4-pole TRRS configuration. This allows for additional signals, such as a microphone signal, to be transmitted via the same connection in addition to stereo audio. One of the connectors has a 90° angled connection, allowing the cable to be easily connected when the port is difficult to access. The connectors feature gold-plated contacts for a stable electrical connection and low contact resistance. The cable has a flexible construction and is suitable for connecting mobile devices to audio systems or car radios. Specifications Brand: DELOCK Cable type: jack audio cable Audio type: analog audio connection Connector 1: 3.5 mm jack male Connector 2: 3.5 mm jack male 90° Connector type: TRRS (4-pole) Mono / stereo: stereo with microphone Contact material: gold-plated Cable type: round cable AWG: 24 Cable length: approx. 5 m Color: black Certifications: CE, RoHS, REACH, WEEE Explanation 3.5 mm jack: A commonly used audio connector for headphones, AUX connections, and portable audio equipment. This connection is used on smartphones, tablets, laptops, car radios, and various audio devices. Angled jack connector: A connector where the cable exits the plug at a 90-degree angle. This allows the cable to be connected in hard-to-reach places and reduces the risk of cable breakage at the connection point. TRRS connector: A jack connector with four contacts (Tip, Ring, Ring, and Sleeve). This allows stereo audio and a microphone signal to be transmitted via a single connection. CTIA standard: A connection standard for 4-pole jack connectors used in smartphones and tablets. The pinout is left audio, right audio, ground, and microphone. Gold-plated contacts: A thin layer of gold on the contact surface of the connector that reduces oxidation and ensures a stable electrical connection. Applications • Connecting a smartphone or tablet to a car radio or audio system • Connection between mobile devices and Hi-Fi systems • Use with headsets with combined audio and microphone connection • Connection between multimedia devices and speakers Types of jack connectors 6.3 mm jack: A larger jack connector primarily used with professional audio equipment, musical instruments, 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 two-contact jack configuration. The tip carries the audio signal, and the sleeve acts as ground. This configuration is used for mono audio signals. TRS (Tip-Ring-Sleeve): A three-contact jack configuration. This allows two audio signals to be sent, for example, a left and right channel for stereo audio. TRRS (Tip-Ring-Ring-Sleeve): A four-contact jack configuration. This type of connection allows a microphone signal to be transmitted via the same connector in addition to stereo audio. Explanation of audio signals Balanced audio: A method of audio transmission using two signal wires and a ground. Interference picked up along the way is canceled out at the receiver, resulting in a more stable audio signal. Unbalanced audio: A form of audio transmission using one signal wire and one ground wire. This type of connection is widely used in consumer electronics. Stereo audio: An audio system using two separate channels: a left and a right channel. Mono audio: An audio system using only one audio channel. Explanation of certifications CE: Indicates that the product complies with European directives for safety, health, and environmental protection. RoHS: European directive restricting the use of hazardous substances such as lead, mercury, and cadmium. REACH: European regulation for the registration and control of chemical substances in products. WEEE: Directive for the collection and recycling of electrical and electronic equipment.
