This is a precision microwave interconnect — the 2.4mm interface is the standard for vector network analyzer (VNA) test ports and high-frequency instrumentation, where the connector's bandwidth directly determines the measurement floor. The compression-style contact termination eliminates solder from the RF launch, preserving the impedance profile through the board transition. ## What the 50 GHz and 500-Cycle Ratings Mean for Your Test Bench The 50 GHz maximum frequency is the connector's usable bandwidth — at this interface, the 2.4mm geometry supports a clean TEM mode well beyond 40 GHz, where an SMA or 3.5mm connector would begin to exhibit higher-order mode resonances. The compression termination is a solderless, rework-friendly attachment: the center pin is pressed onto a PCB launch pad, and the flange is screwed down. This avoids the thermal stress and impedance perturbation of a soldered center pin, which matters when every 0.1 dB of insertion loss repeatability counts. ## Construction and Environmental Reach The body is machined stainless steel with a silver finish, providing corrosion resistance and a stable ground reference. The threaded fastening and flange mounting give a vibration-resistant panel attachment; the shield is terminated via screw, which ties the connector body to chassis ground with a low-inductance path.","metaTitle":"Samtec 240-J-P-EP-ST-CMM-1 2.4mm Jack, 50 Ohm, 50 GHz","metaDescription":"Samtec 240-J-P-EP-ST-CMM-1 2.4mm female jack, 50 Ohm impedance, DC to 50 GHz, gold-plated beryllium copper contact, 500 mating cycles, compression termination","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Samtec Inc.","Series":"240","Package":"Tray","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"-","Cable Group":"-","Body Material":"Stainless Steel","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Surface Mount","Connector Type":"Jack, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"220 V","Connector Style":"2.4mm (APC-2.4, OS-50)","Frequency - Max":"50 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Flange","Ingress Protection":"-","Shield Termination":"Screw","Base Product Number":"240-J-P-EP","Contact Termination":"Compression","Dielectric Material":"Polyetherimide (PEI)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$41.6900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/83dc90cb4faaf591f63a67fb7081f46d.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/240-J-P-EP-ST-CMM-1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the Samtec 240-J-P-EP-ST-CMM-1 and how do I get a price?","answer":"No stock-holding or fixed price is published for this precision RF connector."},{"question":"Is the 240-J-P-EP-ST-CMM-1 compatible with standard SMA connectors?","answer":"No. The 2.4mm interface (APC-2.4, OS-50) is not mechanically or electrically compatible with SMA, 3.5mm, or 2.92mm connectors.
