Rated 1 A at 12 VDC, the jack carries silver-plated brass and phosphor bronze contacts inside a polyoxymethylene (POM) housing, with a single internal switch that opens on plug insertion. ## Termination and panel fit Termination is solder eyelet — the centre conductor, ring, and switch tabs are hand-solderable after the jack is fastened to the panel. The unshielded brass body and black/silver finish suit chassis-mount audio inputs where a threaded M6 lock ring provides mechanical retention against cable pull. The actual contact diameter is 0.142\" (3.60 mm), accepting standard 3.50 mm (1/8\") mini plugs. Operating temperature spans -20°C to 85°C.","metaTitle":"MJ-3502 CUI Devices Phone Jack, 3.5mm, Mono, R/A","metaDescription":"CUI Devices MJ-3502 phone jack: female, 3.50mm mono, 1 A, 12 VDC, panel mount through-hole right-angle, solder eyelet termination, silver-plated contacts","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["USB, Type-C & HDMI Connectors","Audio Connectors"],"specifications":{"Mfr":"CUI Devices","Gender":"Female","Series":"-","Package":"Bag","Features":"Mounting Hardware, Thread Lock","Includes":"2 pcs - 1 Connector, 1 Nut","Shielding":"Unshielded","Body Color":"Silver, Black","Termination":"Solder Eyelet(s)","Thread Size":"M6","Signal Lines":"Mono","Body Material":"Brass","Cable Opening":"-","Mounting Type":"Panel Mount, Through Hole, Right Angle","Connector Type":"Phone Jack","Product Status":"Active","Actual Diameter":"0.142\\\" (3.60mm)","Panel Hole Size":"0.236\\\" (5.99mm)","Voltage - Rated":"12VDC","lifecycle_stage":"unknown","Contact Material":"Brass, Phosphor Bronze","Housing Material":"Polyoxymethylene (POM)","Insulation Color":"-","Internal Switch(s)":"Single Switch","Mating Length/Depth":"-","Current Rating (Amps)":"1 A","Operating Temperature":"-20°C~85°C","Contact Material - Plating":"Silver","Number of Positions/Contacts":"2 Conductors, 3 Contacts","Industry Recognized Mating Diameter":"3.50mm (0.141\\\", 1/8\\\", Mini Plug) - Headphone"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6100","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.61000","currency":"USD"},{"qty":10,"price":"$1.40000","currency":"USD"},{"qty":25,"price":"$1.34080","currency":"USD"},{"qty":50,"price":"$1.31100","currency":"USD"},{"qty":100,"price":"$1.25140","currency":"USD"},{"qty":250,"price":"$1.13220","currency":"USD"},{"qty":500,"price":"$1.04282","currency":"USD"},{"qty":1000,"price":"$0.89385","currency":"USD"},{"qty":2500,"price":"$0.83426","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/df02c86075f5f43c8b730e91dea38b6e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the panel hole size required for MJ-3502?","answer":"The panel hole size is 0.236\" (5.99 mm).
