Abstract: Rectangular connectors are an integral part of any electronic system, allowing for the safe and reliable connectivity of various components and systems. One example of such a connector is the EM35MR-4SC connector and housing. This article explains the key features and operation of this type of connector, as well as its common applications.

Introduction: Rectangular connectors form the basic building block for many different types of electronic systems. They provide reliable connections, as well as carrying power, data, and other signals with minimum loss, and are designed to withstand a wide range of environmental conditions. The EM35MR-4SC is one such rectangular connector that is used in a variety of applications.

Physical Design: The EM35MR-4SC connector consists of two mating halves, with each half consisting of a connector housing and terminals. The housing is of plastic mold, with a front panel overall length of 25.4 millimeters (1 inch) and a rear panel overall length of 12.7 millimeters (0.5 inches). It is designed to be compatible with a wide range of panel sizes, from 0.5 to 1.0 inches. The terminals are of a standard metal compression spring design, and are preassembled into the housing during manufacturing.

Electrical Characteristics: The EM35MR-4SC connector is typically used for low voltage (up to 24 volts) and low current (up to 5 amperes) applications. Its electrical characteristics include a contact resistance of less than 5 milliohms, a dielectric strength of 400 volts minimum, and an insulation resistance of more than 100 megaohms. The contacts are also designed to be shock resistant, with a minimum Cat 2 vibration rating.

Environmental Characteristics: The EM35MR-4SC connector is also designed to meet a wide range of environmental requirements. It is rated for temperatures from -20 to 105 degrees Celsius (-4 to 221 degrees Fahrenheit), and is resistant to water, dust, and corrosion. The connector is also RoHS compliant, meaning that it is free from hazardous substances.

Key Features: Some of the key features of the EM35MR-4SC include a quick connect/disconnect design, compatibility with a wide range of panel sizes, a reliable and dependable connection, a low profile design, and a locking feature to prevent accidental disconnection. It is also designed to support multiple applications, such as audio, video, and power.

Working Principle: The working principle of the EM35MR-4SC connector is relatively simple. When the two halves of the connector are brought together, the contacts between each half make contact with the pins on the other half, completing the circuit. The spring mechanism on the terminals provides a reliable connection, ensuring that the connection is solid and secure. The connector is also designed to lock when the two halves are connected, to prevent accidental disconnection.

Applications: The EM35MR-4SC connector is used in a wide variety of applications, such as audio/visual equipment, computers, medical equipment, security systems, robotics, and automotive systems. It is often used as a power connector, connecting power and data lines to the source. It is also commonly used for transmitting signals, as it is able to provide reliable and consistent connections.

Conclusion: The EM35MR-4SC is a reliable and dependable rectangular connector that is designed for low voltage and low current applications. It features a quick connect/disconnect design, compatibility with a wide range of panel sizes, and a locking feature to prevent accidental disconnection. It is used in a wide variety of applications, such as audio/visual equipment, computers, medical equipment, and automotive systems.
