Rectangular Connectors - Headers, Receptacles, Female Sockets - are a type of connector designed to conduct electrical signals between two or more electro-mechanical components. Within this group, the 90148-1132 is a particular type of female receptacle, sized for 0.1" and 2.54mm pin spacing. The 90148-1132 is composed of a cavity with connector pins contained a center body, the range of functions depending on the application. In this article, we will discuss the functions and working principles of the 90148-1132.

Applications

The 90148-1132 offers a versatile range of applications, from extending a connection between existing components to providing a convenient interconnection alternative. This particular female receptacle is often used in areas such as:

• Data bundle termination
• Wire to board connectors
• Telecommunication and computer modules
• Relay socket applications
• Signal line applications
• Instrumentation panel wiring

The versatility of the 90148-1132 makes it particularly useful in devices that require a variety of signal lines to be interconnected. It is often used in product line manufacturing, as it is designed to simplify the assembly process while also increasing electrical integrity.

Design

The body of the 90148-1132 receptacle is made of a single piece of stamped and formed brass. This provides durability and electrical insulation when the pins are inserted. The pins are made of nickel plated copper and feature an anti-flux coating to ensure the electrical connection is reliable. The two halves of the body are held together by two spring-loaded plastic clips that provide tension to ensure a secure connection with a mating connector.

The pins in the 90148-1132 are positioned at a 0.1" pitch, allowing for greater flexibility when connecting to other components. They also feature a common mating point at the center of the body, making it easy to establish continuity. This also prevents the need to make multiple connections to piece together a signal line.

Specifications

The 90148-1132 has a current rating of 2.5A, operating at a temperature range of -55°C to +125°C. It is also capable of withstanding up to 16V of insulation resistance. The maximum mating force is 4.5 Newtons and the pin contact resistance is 30mohm max. The wires that can be used with the 90148-1132 include AWG#22-24, and the pins should have a diameter of 0.020-0.035". The 90148-1132 is UL, CSA and VDE approved and is RoHS compliant.

Working Principle

The working principle of the 90148-1132 is simple – the two plastic clips compress the two halves of the body together when a mating connector is inserted, making a secure electrical connection. This connection is maintained by the spring-loaded nature of the clips, which provide tension to hold the two halves together. The pins then conduct the electrical signal from the 90148-1132 to the mating connector.

The arrangement of the pins in a 0.1" pitch allows for multiple configurations, offering more flexibility in the design of the device. This is why it is often used in devices that require a variety of signal lines to be interconnected. The common mating point at the center of the body also eliminates the need for multiple connections.

Conclusion

The 90148-1132 is a versatile female receptacle designed for 0.1" and 2.54mm pin spacing, making it particularly useful in areas such as data bundle termination, wire to board connectors, telecommunication and computer modules, relay socket applications, signal line applications, and instrumentation panel wiring. It has a current rating of 2.5A, is UL, CSA and VDE approved, and is RoHS compliant. The working principle is simple – two plastic clips compress the two halves of the body when a mating connector is inserted, making a secure electrical connection between the pins of the connector.
