What is the difference between MY4Z General-purpose Relays and MY4Z-CBG?


Both relays are for switching microloads, but they have different contact mechanisms.

MY4Z have bifurcated contacts, whereas MY4Z-CBG have bifurcated crossbar contacts. CBG models are more reliable for high-frequency microload switching.
Be careful because they have different contact ratings.
