Sumitomo 250 Connectors, Custom Wire Harness Assembly Service

Sumitomo 250-type Connector

 

The Sumitomo 250 Series Connectors are versatile, medium-current connectors known for their reliable electrical performance and extensive variation options. These connectors include LT variants without housing locking functions, LT connectors with locking mechanisms, arm-type connectors, and TIL connectors that feature an integrated arm locking function. Designed with a flat plug-in type terminal, they offer consistent electrical characteristics and have demonstrated field-proven reliability across various applications. A notable feature is the availability of connectors that prevent mis-engagement, particularly useful when the same connector type is used in multiple locations. This compatibility ensures safe and secure connections, minimizing the risk of incorrect installations. The wide range of styles makes them ideal for applications that require dependable medium-current connections with robust performance.
