Power relays are a type of electrical switch that are used to control the flow of current. The 1887112-4 are power relays that are designed to work with loads that require more than 2 Amps to operate. The relays are used in a variety of applications including automotive, industrial, and consumer electronics.

The 1887112-4 power relay has a four-pole design that enables the user to switch one or more of the poles. This relay offers a high level of current protection and also provides a reliable switching action. The contacts are rated for 8 Amps, so they can handle a variety of current levels. The four-pole design allows the user to switch both the normally open (NO) and normally closed (NC) contacts, providing flexibility in applications.

The 1887112-4 relay is designed to meet the UL/CSA standards for power relays. The core component of the relay is a magnetically-shielded sealed reed switch with gold-plated contacts. The sealed reed switch provides an environmentally safe and reliable way of controlling the flow of current. The contacts are designed to minimize contact resistance and provide long life and reliable operation. The magnetically-shielded construction allows for better electromagnetic interference (EMI) protection.

The 1887112-4 power relay works on the principle of electromagnetism. When a voltage is applied to the relay’s coil, it creates a magnetic field that attracts and releases the reed switch’s contacts, thus controlling the flow of current. When the voltage is removed, the reed switch’s contacts return to their original state, thus controlling the flow of current.

The 1887112-4 relay has a wide range of applications due to its versatility. It is commonly used in motor control, instrumentation, automotive electronics, and consumer electronics. It can also be used in conjunction with other relays to provide additional current protection. The relay is designed to work in temperatures ranging from -40°C to 125°C.

In conclusion, the 1887112-4 power relay is a versatile and reliable electrical switch. It is designed to work with loads that require more than 2 Amps to operate, and can handle a variety of current levels. The sealed reed switch construction provides an environmentally safe and reliable way to control the flow of current. The magnetic shielding provides EMI protection. The relay’s four-pole design allows the user to switch both the normally open and normally closed contacts for a variety of applications.
