Signal relays are electrical control devices used in various applications. In this article, we will focus on the HC4ED-HP-DC48V model from Hirose Electric Co., Ltd., which falls into the category characterized by relays with up to 2 amperes power capabilities. We will discuss the application field and working principle of the HC4ED-HP-DC48V model.

The HC4ED-HP-DC48V is a compact, ultra-small relay designed for use in automated assembly applications. The single-pole, double throw (SPDT) contact configuration provides contact switching for two independent circuits. It has a contact rating of 2A at 48V DC – suitable for use with modern equipment, and is available with various actuator types, including: plunger, spring, etc. These relays are available in normally open (NO) and normally closed (NC) configurations.

The primary application field for the HC4ED-HP-DC48V is in automated assembly operations, such as pick-and-place and conveyor systems. It offers a combination of reliable contact switching and compact size, making it ideal for use in a range of industrial automation solutions. This model has been tested for countless cycles and is highly durable and reliable. It can also be used in telecommunications systems, security systems, and other peripherals.

The HC4ED-HP-DC48V signal relay works on the principle of electromagnetism. This relay has an electromagnetic armature connected to a switch, which is either normally open (NO) or normally closed (NC). When an alternative current is passed through the relay, a magnetic field is created which attracts the armature and operates the switch. The force of attraction between the electromagnet and armature is proportional to the current applied, and the current required to operate the switch is known as the pick-up voltage.

Once the relay is operated, the contact configuration will switch, and the circuit will be connected to the other point. The opening and closing of the switch is controlled by the current applied to the relay. When the current is removed, the armature will become de-energized, which will cause the contacts to return to their original configuration. This behavior is known as latching, meaning that once the relay is operated, the contacts remain in the same position, regardless of power being removed. The relays come with LED indicators which show the statuses of the relay.

In conclusion, the HC4ED-HP-DC48V signal relay is a reliable and durable device, suitable for use in a range of industrial automation solutions. It offers reliable contact switching and a compact size, making it ideal for use in automated assembly operations, such as pick-and-place and conveyor systems. The working principle is based on electromagnetism, and the device latching after operation preserves the circuit’s configuration. We hope this article has given you a better understanding of the HC4ED-HP-DC48V signal relay and its application field and working principle.
