Convergence Purity Magnets from Sanbros Engineering Works are precision magnetic beam-adjusting devices designed for the neck region of in-line type color picture tubes. Each unit consists of three pairs of plastic magnet rings, typically 2-pole, 4-pole, and 6-pole configurations, engineered to create a magnetic field distribution that enables smooth electron beam adjustment. The standard neck diameter for these magnets is 29 mm, with sizes available for 14", 20", 21", and 29" CRT tubes, ensuring compatibility with legacy display technologies still in use in industrial, medical, and military applications.
The magnets are manufactured using ferrite or AlNiCo magnetic alloys, materials known for their stability and precision in electron beam control. The rings are molded from plastic compounds embedded with magnetic particles, a construction method that allows for fine tuning of the magnetic field to centralize and rotate the electron beam within the color picture tube. This design is critical for maintaining color alignment in CRT displays, where even minor misalignments can degrade image quality.
These components are primarily sourced by repair technicians and OEMs maintaining legacy CRT equipment, where replacement parts are no longer produced by original manufacturers. Sanbros Engineering Works supplies these magnets as spare parts for industrial displays, medical imaging devices, and aviation instruments that rely on cathode ray tube technology. Buyers should confirm compatibility with their specific tube model and verify the pole configuration required for their application before ordering.

Before ordering Convergence Purity Magnets from Sanbros Engineering Works, verify the compatibility of the neck diameter and pole configuration with your CRT tube model. Request the supplier’s technical datasheet to confirm the magnetic field specifications, as these directly impact electron beam alignment. Check whether the magnets are suitable for your specific application, whether industrial, medical, or military.
Confirm the logistics details, including lead time, which is not specified in the listing. Clarify the Incoterms offered, such as FOB or CIF, and whether the supplier can accommodate your preferred shipping method. Payment terms should also be discussed upfront, as these are not provided. Ensure the packaging protects the magnets from demagnetization during transit, as exposure to strong external fields can affect performance.
For quality checks, inspect the magnets upon arrival for physical damage or deformities in the plastic rings, as these can disrupt the magnetic field. Request a certificate of conformance to verify the magnetic properties, such as residual induction and coercivity, meet the typical industry standards. If possible, conduct a functional test by installing the magnets in a sample tube to confirm proper electron beam convergence before full-scale deployment.
