Omron MY4N 6VDC (S) Miniature Power Relay Technical Article
The Omron MY4N 6VDC (S) miniature power relay is a low-voltage DC coil relay intended for control circuits where a 6 VDC signal is available. While 24 VDC is more common in modern industrial automation, 6 VDC relays remain important in electronic control boards, test equipment, compact machine interfaces, specialized control modules, and legacy systems.
This relay belongs to the Omron MY family, which is known for general-purpose plug-in relays with practical industrial features. The MY4N design provides a 4PDT contact form, allowing one coil to operate four independent changeover contacts. This makes the relay valuable when a low-voltage control signal must manage several isolated circuits.
Technical Profile
The Omron MY4N 6VDC (S) miniature power relay is built around a 6 VDC coil and a plug-in terminal structure. As part of the MY4N relay format, it is associated with 4PDT switching, an operation indicator, socket-based mounting, and a compact relay body for panel or equipment installation. In the MY series, comparable 4PDT models use gold-clad silver alloy contacts and support general-purpose control switching where the electrical load is correctly matched.
Why a 6 VDC Coil Is Selected
A 6 VDC coil is useful when the control side of the system is powered by a low-voltage electronic supply. This may appear in custom equipment, laboratory devices, embedded control systems, small machinery, and retrofit applications. Selecting a relay with the correct coil voltage prevents overheating, unreliable pull-in, or coil failure.
4PDT Switching Advantage
The major strength of this relay is its four changeover contact sets. A designer can use one low-voltage coil signal to switch several circuits at once, while keeping those circuits electrically separated. This is useful for status feedback, signal routing, interlock logic, auxiliary outputs, and multi-branch control functions.
Installation and Selection Notes
The relay should be installed with a compatible socket and within its specified electrical limits. Load type must be reviewed carefully. Resistive loads are simpler, while inductive loads such as coils, solenoids, and small motors can create voltage spikes during switching. Proper protection can improve service life and reduce electrical noise.

Omron MY4N 6VDC (S) FAQ
What is the Omron MY4N 6VDC (S) miniature power relay used for?
It is used in low-voltage DC control circuits where a 6 VDC coil signal must operate multiple relay contacts.
Is 6 VDC common in industrial panels?
It is less common than 24 VDC, but it is still used in specific electronic, testing, embedded, and legacy applications.
What does the 4PDT contact layout mean?
It means the relay has four independent changeover contacts controlled by one coil.
Can it replace a 24 VDC relay?
No. The coil voltage must match the control voltage. A 6 VDC relay should not be replaced with a 24 VDC model unless the control circuit is redesigned.
Why is socket mounting useful?
Socket mounting allows easier replacement, reduces wiring disturbance, and helps maintenance teams service the relay more efficiently.
