Working Principle

The 91601-403ALF is a standard two-row right-angle header. It contains four (4) pins in two (2) rows, with a 0.100” (2.54 mm) pitch. The pins can be soldered or crimped into a circuit board, and the two (2) mounting holes can be tapped or used for mounting. The connector is designed to mate with a compatible rectangular receptacle, such as the 91601-402ALF, which can be purchased separately.When plugging in the 91601-403ALF rectangular connector, the force generated by tightening the screws helps create a secure connection between the pins, which prevents loosening with vibration. This provides a reliable connection in even the most extreme environments.

Conclusion

The 91601-403ALF rectangular connector is a type of header designed for use in a variety of applications. It offers a reliable connection and can withstand harsh conditions and environments. This connector is well-suited for applications such as industrial automation and medical equipment. It has a 0.100” (2.54 mm) pitch with four (4) pins and two (2) mounting holes, and is UL and CSA approved. Additionally, it is RoHS compliant and Lead-Free. The 91601-403ALF can be installed horizontally or vertically and is designed to mate with a compatible rectangular receptacle.
