The transducer is tuned to a specific resonant frequency (typically 20 kHz for welding, 40 kHz for cleaning) and converts high-voltage electrical energy from the generator into mechanical vibration at the horn tip.<\/p>\n<p>A compatible replacement must match:<\/p>\n<ul>\n<li><strong>Resonant frequency<\/strong> (20 kHz or 40 kHz within \u00b10.5 kHz)<\/li>\n<li><strong>Physical mounting dimensions<\/strong> (bolt pattern, flange OD, stud thread)<\/li>\n<li><strong>Impedance<\/strong> at resonance (to avoid generator fault trips)<\/li>\n<li><strong>Power handling capacity<\/strong> (watts rated continuous)<\/li>\n<\/ul>\n<p>Sino Sonics matches all four parameters for each cross-reference listed below.

Price \u2014 30\u201350% Below OEM List<\/h3>\n<p>A Branson 900-series replacement from the OEM channel can run $400\u2013$600 depending on your distributor. Our 900-series compatible unit ships at $260 \u2014 same interface, same frequency, factory-tested output.<\/p>\n<h3>2. Lead Time \u2014 24 Hours vs. Weeks<\/h3>\n<p>Branson OEM replacement parts often require ordering through a distributor with 2\u20136 week lead times. We maintain on-shelf stock of all four cross-reference models. Same-day processing on orders placed before 2 p.m. China Standard Time.<\/p>\n<h3>3. OEM &amp; Private-Label Options<\/h3>\n<p>Machine builders and MRO distributors can order under their own brand name. We supply the transducer with your labeling, documentation, and box insert. MOQ and pricing on request.<\/p>\n<h3>4. Cross-Match Service<\/h3>\n<p>Not sure which model fits your machine? Send us your Branson model number, generator serial, or a photo of the existing transducer flange. Our engineering team will confirm compatibility before you order.<\/p>\n<h3>5.
