About

JST 2.54mm SM Series Connectors — Precision-Engineered for Reliable Wire-to-Wire Connections The JST 2.54mm SM series is one of the most widely adopted wire-to-wire connector families in electronics engineering, trusted by designers and manufacturers across automotive, industrial automation, consumer electronics, and robotics applications. Keszoox stocks a comprehensive range of SM series components — from housings and contacts to pre-crimped wire assemblies — so you can source everything you need from a single, reliable supplier. Why Engineers Choose JST SM 2.54mm Connectors The SM series features a 2.54mm (0.1") pitch , the industry-standard spacing that aligns perfectly with breadboards, PCB headers, and DIP-footprint layouts. Its positive locking mechanism ensures a secure, vibration-resistant mating that won't loosen under mechanical stress or thermal cycling — critical for field-deployed and mission-critical assemblies.
