Signal Relays

Signal Relay Definition

Signal relays are mainly used for lower than 2A load switching, and can be used in various applications such as telecom & network devices, test and measurement equipment, and security devices.

About Signal relays

Signal Relay 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.

Signal Relay 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.

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.
