BENDIX/ TCM/ CMI

Bendix, TCM, CMI magnetos are commonly referred to as "Bendix Mags", and have been in continuous production since the 1947. Their light weight compact design, high output and reliability, make them the Best Choice for any aircraft. Aerostar to Zlin and every application in between are best with "Bendix".

Bendix S-20 Series

The S-20 Series magneto is designed for both single and dual impulse-coupled applications. Earlier models require external P-Lead filters when used in applications involving radios. However, the latest "Short Cover" S-20 Series features a built-in feed-through capacitor that effectively filters out noise, ensuring seamless radio performance.

If you are upgrading from the earlier style (with an external P-Lead filter) to the latest "Short Cover" magneto, it is critical not to use the external P-Lead filter with the new model. Combining the "Short Cover" magneto with an external P-Lead filter alters the overall capacitance, which can negatively impact the performance of the "Short Cover" magneto.

Bendix "Short Cover"

The S-20 Series "Short Cover" magneto is easily recognized by its rear contact cover, where the feed-through style condenser is mounted. This design simplifies the stud-type switch and retard connections for "Shower of Sparks" magnetos, eliminating the need for special outlet kits.

Additionally, the model number identifies the "Short Cover" configuration with the letters SC preceding the dash and number—for example, S4LSC-21.

Short Cover (SC) magnetos are fully interchangeable with earlier S-20 and S-200 models. Pairing an SC magneto with an older style magneto on the same engine installation is fully permissible. All SC magnetos are FAA/PMA approved, ensuring quality and reliability.

Bendix S-200 Series Straight Drive and

"Shower of Sparks"

Bendix S-200 Series magnetos, known as "Shower of Sparks" magnetos, utilize an ignition vibrator in combination with a retard contact assembly in the left magneto for engine starting. The right magneto is a standard single-point magneto and does not incorporate a retard contact assembly.

These magnetos are available in two configurations: "Long Cover" and "Short Cover". The "Short Cover" style features a feed-through condenser and a simplified ring terminal P-lead connection, eliminating the need for external P-lead filters. In contrast, the "Long Cover" style requires a P-lead outlet kit. It's important to note that split washers should never be used on the "Short Cover" condenser stud as this may compromise performance.

Both styles are designed for reliable functionality and compatibility across various installations.

Bendix S-1200 "The Best of the Best"

This magneto series stands as the pinnacle of performance, capable of both impulse-coupled and "Shower of Sparks" configurations. With the ability to achieve voltages as high as 28,000 and certified to operate at altitudes up to 25,000 feet unpressurized, it’s the magneto of choice for winning Reno Formula One Racers!

These magnetos utilize the same feed-through style condenser (P/N 10-400615) as the "Short Cover" S-20/S-200 series. Important note: Never use split washers on these condensers. Over-torquing the condenser stud while attempting to compress a split washer can lead to premature failure of the condenser.
