Rectangular Connectors - Headers, Male Pins

The 20021621-00034T4LF is a 3.96 mm square post, tab-locking, shrouded header. This type of electrical connector is generally used to make electrical interconnection between board and cable. It is also known as a male pin connector, and is used in a wide range of applications.

Connector Construction

The 20021621-00034T4LF is a shrouded header connector with two mating parts, a receptacle and a header. The receptacle has a plastic housing with a 3.96 mm square post and a tab-locking feature. The header has a mounted plastic housing with contact pins on the interior. The contacts are made from gold-plated copper.

Insulator

The insulator is made from a durable glass-filled nylon. This material provides a high level of abrasion and chemical resistance, excellent electrical insulation, and easy handling. It also provides a great amount of heat resistance, up to 125°C (257°F).

Features and Benefits

• Low profile and compact
• Good mechanical strength and shock resistance
• Lock tab prevents unintentional mating
• Gold-plated contacts provide effective electrical connections
• Durable glass-filled nylon insulator
• High temperature operation up to 125°C (257°F)

Applications

The 20021621-00034T4LF is ideal for a variety of applications including series connection applications such as battery connection and circuit board connection. It is also suitable for electrical equipment in which a reliable and secure connection is needed. Examples include medical equipment, automotive, industrial robots, and consumer electronics.

Working Principle

The working principle of the 20021621-00034T4LF is based on the use of an electrical connector, which is a mechanical device used to join electrical circuits together. It is comprised of two parts, the receptacle and the header. The receptacle, which has a plastic housing, holds the contact pins of the header and creates electrical connections when the header is mated and locked in place. The header forces the receptacle contact pins into alignment when these are engaged. This ensures reliable electrical connections and prevents unintentional disconnection.
