Relay Basics 2-1 Signal Relays | OMRON - Korea

Definition

Relays are mainly used for more than 3A load switching, and equipped in household appliances, such as refrigerators, washing machines, and AV devices, as well as various FA equipment, industrial equipment, and household equipment.

Features

Signal relays offer superior contact reliability even with a small signal load owing to its gold-pasted contact and bifurcated crossbar structure (see figure).
Since signal relays are mainly used to switch current, they mainly have c-contact structure. They are compatible with reflow mounting. Multiple mounting is also possible for reel packages.

Types

Omron's signal relays continue to contribute to society through a wide range of variations including general purpose, small, high sensitivity, and high-frequency types and a stable quality.

Structure

Main surface mount signal relays consist of the following parts.
The coil is secondary molded, and high insulation performance between the coil and the contact is achieved while being small-sized.
