Omron MY4H-24VDC
Hermetically Sealed Miniature Power Relay | 24 VDC Coil | 4PDT Contacts | 3 A Resistive Load | Plug-In Terminals
Product Detailed Description
The Omron MY4H-24VDC is a hermetically sealed miniature power relay designed for switching and control applications in industrial and electrical equipment. It features a 24 VDC coil and four changeover contact sets (4PDT), allowing one control signal to switch multiple independent circuits. The sealed construction helps protect the relay’s internal contacts from environmental contamination.The relay has a maximum contact current of 3 A, with contact ratings depending on the load type and voltage. For example, the manufacturer specifies 3 A for resistive loads at 110 VAC or 24 VDC, while inductive-load ratings are lower. It uses plug-in terminals and is intended for installation with a compatible 14-pin relay socket. Verify socket wiring, contact ratings and coil voltage before installation.
