TE Connectivity FASTON 250 Series Ultra-Fast Plus Tab Crimp Terminal
FASTON 250 series Ultra-Fast Plus fully insulated tab crimp terminals designed to prevent shock and electrical short circuits from exposed leads. The housings of these FASTON 250 series Ultra-Fast plus tab crimp terminals completely enclose a tin plated copper alloy FASTON tab contact which is recessed within the housing to allow its use in 600V applications. The tab and wire barrel part of the housing is made from type 6/6 nylon whilst the insulation barrel is made from premium grade nylon with minimum spring-back which retains the insulation crimp shape and provides strain relief. These FASTON 250 series Ultra-fast plus crimp terminals terminate 26-10 AWG solid, fused and stranded wire.
