BSF-20PM-4
Tracking System Unit
Description
BSF-20PM-4 tracking-system unit
BSF-20PM-4 is an aircraft tracking-system block identified by drawing 6Zh3.031.013-04. It belongs to the 20PM electronic equipment group and is listed separately from BSF-20P and other BSF executions. The suffix PM-4 and the drawing ending -04 are therefore essential parts of the product identity.

Role in the 20PM equipment group
MiG-29 technical material places the BSF channel within the 20PM system alongside BUR-20PM and other control and indication channels. The available source confirms system membership and test interaction but does not publish a complete internal circuit or terminal table. The block should be described as a tracking-system unit rather than assigned invented voltage or performance values.
Documented MiG-29 context
Repair and inventory records connect BSF-20P-family equipment with the MiG-29. The reviewed system-check table explicitly names the 20PM BSF channel in the OEPnK-29 test sequence. This supports the aircraft and system context while the exact effectivity of the PM-4 execution must still be checked by drawing and aircraft records.
Identification and compatibility
BSF-20PM-4, BSF-20P and other BSF-20PM variants are related but not automatically interchangeable. Compare the full plate, 6Zh3.031.013-04 drawing, connectors, rack position and 20PM system execution. A shared housing or the abbreviation BSF is insufficient for substitution.
Inspection and ordering
Inspect the housing, mounting surfaces, connector contacts, seals and plate. Functional verification requires the correct 20PM / OEPnK-29 bench sequence and known interfaces. State the exact BSF-20PM-4 marking, aircraft and system, quantity, condition and document requirements in the enquiry. Related units are under Electronic Control Units.
