Rectangular Connectors - Headers, Male Pins – 87402-115 – Application Field and Working Principle

87402-115 is an industrial standard rectangular connector, with application in multiple industries. Headers are designed to provide connections between two or more mating components. 87402-115 rectangular connectors consist of a connector housing, metal contacts, and mating interfaces. These connectors are often referred to as header connectors or male pins. They typically use a spring-loaded female terminal with a crimp-on terminal.

87402-115 features headers that are designed with the same dimensions as other series of rectangular connectors. The connectors have an insulated housing made of thermoplastic or thermoset plastic. They are available in a variety of pin counts and space configurations. The contacts are composed of brass or phosphor bronze. The contacts are usually stamped from sheet stock.

The primary applications for 87402-115 are for signal and power contacts, and they comply with EIA 485A. These connectors are often used to provide a quick-connect and disconnect interface for temporary wiring. A common application of 87402-115 is in industrial control cabinets. The connectors are often used in military and aerospace applications and in automotive and medical equipment.

The 87402-115 has the following features:

• Temperature range of -55° C to + 125° C
• 3A rated current, or 5A peak
• RoHS compliant
• Insulated housing made of thermoplastic or thermoset plastic
• Contacts made of brass or phosphor bronze
• Female terminal with crimp-on terminal

The working principle behind the 87402-115 is relatively simple. A female connector is mated with the male plug and the contacts of the female connector are secured to the male plug with a crimp-on terminal. The contacts on the male plug are then inserted into the female connector and the two components are locked together. The contacts on the female connector are then aligned with the contacts on the male plug and sealed against each other. The contacts are then made electrical contact with each other, allowing for the transmission of an electrical signal or power. The contacts on the male plug can be removed or replaced as needed.

The 87402-115 is a reliable and cost-effective rectangular connector, perfectly suited for a wide range of industrial and commercial applications. It is designed to provide a quick and secure connection for temporary wiring, and is rated for high temperatures and a variety of current levels. The combination of a thermoplastic or thermoset plastic housing and brass or phosphor bronze contacts ensures a durable and reliable connection. This makes the 87402-115 a preferred choice for many applications, such as in industrial control cabinets, automotive and medical equipment, and in military and aerospace applications.
