    S7121-42R is a contact for RFI and EMI applications. It is composed of fingerstock, gaskets and contact elements and is designed for a wide variety of demanding applications. The contact elements provide a reliable and robust connection for various sensing and signal transfers, and the fingerstock acts as an anti-vibration device to protect the contact elements from damage. The gaskets provide a seal against humid or corrosive environments, while the contact housing ensures mechanical strength. It is suitable for a large range of applications, including automotive, aerospace, medical, and industrial electronics.

    The fingerstock of the S7121-42R is made of copper-plated carbon steel or copper-plated non-ferrous steel. It has a long service life and provides superior contact resistance and electrical continuity. It is designed to maximise contact strength and consistency with minimal contact resistance and leakage. The fingerstock also has a unique shape which helps ensure that contact is maintained even when subjected to shock and vibration. The gaskets are made of rubber or silicone, and are designed to provide an effective seal against dust, moisture and vibration. The contact elements are manufactured from brass or stainless steel, and are designed to provide excellent contact strength and electrical continuity.

    The working principle of the S7121-42R is relatively simple. When current is applied to the S7121-42R contact, it causes a magnetic field to be generated around the contact. This magnetic field attracts and holds the contact elements, creating a reliable electrical connection. The contact elements also maintain a gap between the two mating surfaces, ensuring that contact is maintained even when subjected to shock and vibration. The gaskets also provide a seal to prevent dust and moisture from entering the connector.

    The S7121-42R is designed to be used in a wide variety of applications. It is suitable for use in automotive, aerospace, medical, and industrial electronics. It is also used in a range of commercial applications, such as kitchen appliances, consumer electronics, and audio equipment.
