5-Position SIL Housing

A 5-position SIL housing is a precision-molded plastic connector designed to hold a single row of five crimp terminals, providing a reliable and standardized method for electrical connections in various electronic applications. These housings, typically manufactured from glass-filled polyamide (nylon) or similar engineering thermoplastics, offer robust environmental protection and secure terminal retention while maintaining precise pin spacing for reliable mating.
