M83519/2-3 SHIELD TERMINATOR

Raychem Solder Sleeve Shield Terminator — Standard with 22 AWG Lead for Motorsport Shielded Cable Grounding

The S02-03-R is a Raychem solder sleeve shield terminator in standard sizewith an integrated 22 AWG lead wire, used for terminating the braid shield on shielded cables in motorsport and aerospace wiring harnesses. The solder sleeve format provides a clean, permanent, no-solder-iron connection to the shield braid — the sleeve contains a pre-loaded solder ring that melts when heat is applied, reflowing into the braid to create a low-resistance, mechanically secure termination in a single heat cycle. This product suits standard shielded cable sizes per M83519/2-3 specification, with an integrated 22 AWG drain lead.

Why Shield Termination Matters in Motorsport

A shielded cable’s noise rejection performance is only as good as the quality of its shield grounding. A poorly terminated braid — loose, high-resistance, or incompletely connected — reduces the shield’s effectiveness and allows residual noise to couple onto the signal conductors. The shield must be connected to chassis ground with a low-impedance path to divert intercepted EMI current effectively. Solder sleeve terminators provide the most reliable and repeatable braid termination method available without specialist equipment — the pre-loaded solder ring ensures complete 360-degree braid-to-termination contact when correctly heat-applied.

Shield-Only vs Lead-Wire Termination

The S02 series adds an integrated 22 AWG lead wire to the solder sleeve, providing a pigtail that can be routed to the chassis ground point when the nearest ground connection is not immediately adjacent to the shield termination. This is the most common solder sleeve format in motorsport harness work, as it accommodates the varied routing geometry of race car wiring without requiring the shield termination to be precisely at the connector body.
