281740-4

Rectangular Connectors - Headers, Male Pins are widely used in various industrial applications to provide stable electrical and data connections. The 281740-4 is a widely used rectangular connector featuring two rows of four gold-plated contacts, ideal for applications requiring wiring two separate electrical circuits and making general connections for a variety of small and low-voltage devices.

The connector is composed of a male plug with four pins, which mate with a female collar that houses a pair of 4-pin headers. The plug housings, made from high-strength thermoplastic, feature a snap-lock structure that allows for quick and easy assembly of the unit. The contact surfaces are gold-plated for enhanced conductivity and corrosion resistance, and feature contact pins that easily slide into the contacts of the female headers. The contact pins are also securely locked into place, ensuring stable connections and reducing the risk of intermittent connection malfunction. The connector allows for customization with additional features such as cable strain reliefs, polarization, and board locks.

The 281740-4 is designed to operate in a variety of industrial settings, with a maximum continuous current of 1A and an operating temperature range of -55 to + 125°C. The working principle involved is relatively simple, with the male plug containing the contact pins being inserted into the female collar. When properly plugged in, the two contacts touch, allowing an electrical connection to be established, providing a reliable and secure connection for the current or data travelling through the contacts.

The 281740-4 connector provides a secure and dependable connection for circuits up to 1A. It features a snap-lock structure for easy assembly and gold-plated contacts for increased conductivity and corrosion resistance. Moreover, customization options such as cable strain reliefs, polarization and board locks make this connector an attractive choice for many industrial applications.
