Ring terminal for 24-26 AWG, #8 stud
The 53403-1: The tin-lead plated copper contact is crimped onto the wire, and the PVDF insulation provides radiation resistance.
Insulation and plating choices
The 53403-1 uses a PVDF insulation rated for radiation environments, distinguishing it from the nylon-insulated 54311-1 and 53055 which lack that rating. Contact finish is tin-lead on the 53403-1, while the 54311-1 and 53055 use tin-only plating.
Active production, RoHS non-compliant
It is marked RoHS non-compliant due to the tin-lead contact finish.
