Power Relays, Over 2 Amps

The MY4ZH-AC110/120 is a 2-pole/10 A, 2-pole/12 A relay for switching circuits at rated voltages up to 250 V and rated switching currents up to 10/12 A. It has an operating temperature range between -25°C to +50°C, and a contact travel of 1 to 2.5 mm. It also has a creepage distance of more than 4 mm, and its two normally open (NO) contacts are capable of switching AC/DC currents. In addition, it has a wide range of auxiliary contacts that can be used to switch on/off other circuits.

The MY4ZH-AC110/120 is mainly used in the industrial automation control system, and it finds applications in such areas as motor control, machine tools, HVAC control, medical equipment, and power supply protection. It features a low switching power consumption, high reliability and long mechanical life due to its built-in spring mechanism.

The MY4ZH-AC110/120 has a working principle based on the pull-in relay, which is an electromechanical relay with two separate circuits. The primary circuit is controlled by an electromagnet and a contact, while the secondary circuit is controlled by a spring-loaded contact. When the primary circuit is energized, the electromagnet pulls in the armature, which causes the contact to move from its open position to its closed position and thus completes the secondary circuit. The spring-loaded contact and the primary circuit then remain in their current positions until a reset signal is sent to the primary circuit, which causes the electromagnet to de-energize and the armature to return to its initial position, thus opening the secondary circuit.

The MY4ZH-AC110/120 is an efficient and reliable relay that is suitable for a wide variety of applications, ranging from industrial automation to medical equipment. It features a low contact resistance, high switching capacity, and long mechanical life, making it an ideal choice for a variety of applications.
