Ultra-Fast fully insulated FASTON receptacles and tabs offer the advantage of a completely protected terminal and a closed barrel wire crimp with comparable electromechanical performance to open barrel “F” crimp FASTON terminals. The user-friendly design combines easy mating with rounded corners. The .187 and .250 series receptacles incorporate a two-stage roll configuration and a cantilever mounted dimple which provides easy insertion and multiple independent points of contact for reduced tab interface resistance. Ultra-Fast fully insulated FASTON terminals, offered as straight receptacles, flag receptacles and tabs, preclude the need for costly electrical safety interlocks or special protective shields to help prevent shock hazards. In addition, electrical short circuits from exposed leads are eliminated, even in equipment requiring close contact spacing.
The Ultra-Fast FASTON receptacle housing completely encloses a tin-plated copper alloy premier FASTON receptacle which has been stress-relieved for increased durability and resistance to abuse. The FASTON receptacle is recessed sufficiently within the housing to allow its use in 600-volt applications. The receptacle portion of the terminal is designed for positive mating with a variety of tabs, including those with shoulders. The housing has a slotted membrane which is displaced by two-tab shoulders allowing proper engagement of tab and receptacle while maintaining the fully insulated characteristic.
This Ultra-Fast quick disconnect tab (EDMO# 4-521098-2) is part of the 0.250 series, accepts 12–10 AWG wire, features a brass terminal, and is yellow in color.
