High Frequency (RF) Relays are devices which are used to control high frequency electrical signals in order to provide sensing, isolation, or switching functions. Among them, the 1617107-2 Relay is an RF relay which employs a low insertion loss and high isolation performance. For it\'s reliability and good performance, this kind of relay is widely used in Wireless Network applications, Radios, Base Station, Test Equipment, Telecommunications and Automation systems.

This RF Relay features a normally closed (NC) contact configuration, which ensures the signal would always follows an 4-port path. In addition, a very low profile package with dual electrostatic shielding has been adapted upon this relay, which further decreases the level of noise and ensures the signal integrity. During automated production, its leads of the relay can be processed to provide reliable and repeatable wiping action on plated through holes of the printed circuit board (PCB).

The working principle of 1617107-2 Relay can be divided into three components: The hermetically sealed reed switch, the magnet core, and the sealed housing. The hermetically sealed reed switch provides the 1617107-2 Relay with secure contact performance and long service life. It\'s made up of two thin strips of metal with electrodes, which are could be easily attracted by the magnetic field generated by the magnet core of this relay. When the instance of attraction has reached a certain level, the strips will establish a connection between the two electrodes, then the contact is closed and the circuit is formed.

The magnet core which is a ring-shaped component in the 1617107-2 Relay plays a role in generating the magnetic field. This component is usually made of ferrite core which consists of two parts, an inner cylinder and an outer cylinder. It can generate a uniform and circular magnetic field at a range of frequencies, thus resulting in a reliable working performance. The hermetically sealed housing is used to prevent the reed switch from external pulse waves or current, thus limiting the over-magnetizing and preventing unnecessary displacement of the contacts.

In order to ensure the stable operation conditions and reduce the impact of any unexpected environment, the 1617107-2 Relay also applies a built-in temperature protection module. By monitoring the temperature of the device, the circuit inside the module will automatically adjusts the magnetic field and reduce the contact force, then the relay switches its status if the temperature is higher than specified limit. Furthermore, this module also provides a circuit of over-temperature protection against the possible short circuiting.

Lastly, thanks for its sophisticated design, the 1617107-2 Relay also delivers a very low current at its contact, this feature enables it to be used in applications which requires a low current driving signal. As a result of its mount-saving capability and wide working temperature range, this relay is widely used RF wireless network applications, such as in Bluetooth, WiFi, or other related applications.
