Rectangular connectors have come to be ubiquitous in electronic systems, and the 91901-31425 is no exception. This type of connector is most commonly used as an array, edge type, or mezzanine (board to board) connector and is usually found in medical, military, and aerospace applications. The 91901-31425 is designed to provide rugged durability, superior electrical performance, and reduced board space.

Design and Features

The 91901-31425 Rectangular Connector is a cost-effective, high-performance connector that utilizes a combination of plugs and headers, as well as PCB mounting hardware. The basic design consists of two interlocking outer housings that are sealed against contamination while achieving high levels of electrical performance. The parts are also constructed to reduce stress on the sockets and pins by distributing the contact force over a wider area. This design allows for easy installation and a secure connection.

This connector system has a wide operating temperature range and offers reliable environmental protection. It is designed for high-vibration environments, where it can be used in low-power or high-current applications. Additionally, it features a low profile design, which allows it to be used in space-constrained applications. The standard version of this connector can accept up to 20 contacts with mating heights up to 4 mm.

Applications

The 91901-31425 is designed to meet a variety of application needs. Its combination of power, performance and reliability make it suitable for use in medical, military, and aerospace applications such as:

• Medical diagnostic and therapeutic equipment
• Defibrillator systems
• Ventilator and respiratory equipment
• Data acquisition and diagnostic systems
• Industrial control systems
• Instrumentation
• Radar/satellite communications
• ISR (Intelligence, Surveillance and Reconnaissance)

Working Principle

The 91901-31425 features two interlocking outer housings, one male and one female. The male housing is designed to accept a mating female housing, which contains pins that make contact with the female contacts on the male housing. This contact is made when the female housing is inserted into the male housing. The connectors are held securely in place with keylock posts and snap-in latches. The pins on the female housing are precision-machined to provide a reliable contact with the female contacts on the male housing.

The 91901-31425 is designed with an insulator between the contacts and the housings to provide electrical insulation and protection of the pins. This insulator also keeps the contacts free from contamination. The housings are also designed with seals to protect against humidity, dust, and vibration.

Summary

The 91901-31425 is a high-performance, cost-effective Rectangular Connector that is suitable for a wide range of applications, including medical, military, and aerospace. Its rugged design offers durable performance in a low profile package and is capable of handling low and high current applications. It is designed with two interlocking outer housings, pins, and seals that keep the contacts free from contamination while providing superior electrical performance. This allows for easy installation and reliable operation in any environment.
