Omron Unveils G7Z High Capacity Relay With Mirror Contacts

Schaumburg, IL - Omron Electronic Components LLC introduces a unique power relay that provides up to 40A Switching Capacity per pole on the N.O. Contact. The resistive load rating is 40A @ 440VAC for N.O. Contact and 25A @ 440VAC for N.C. Contact. The G7Z has an impressive inductive load rating of 22A @ 440VAC on the N.O. Contact (Power factor = 0.3).

The G7Z comes in 2-FormA+2-FormB, 3-FormA+1-FormB, and 4-FormA pole configurations. The 4-FormA version has a maximum current carrying capacity of 160A when each N.O. Contact is wired in parallel.

The powerful G7Z has an auxiliary contact block with "mirror contacts". The form types of the auxiliary contact block are 2-FormA, 1-FormA+1-FormB, and 2-FormB. When using a G7Z Relay with a Form B mirror contact, the user can achieve a 2.5kV Impulse Withstand Voltage or maintain a gap of 0.5mm when the coil is de-energized, even if one or more of the main N.O. Contacts are welded. This makes a G7Z Relay with a 1-FormA+1-FormB or a 2-FormB auxiliary contact block ideal for output control in a safety circuit, as it meets the requirements of EN60947-4-1.

The G7Z is well suited for inverter, solar/fuel battery, and Uninterruptible Power Supply applications. It's also a good candidate for three phase applications when using 3-FormA+1-FormB or 4-FormA models.

The physical size of the G7Z is 62mm (L) x 45mm (W) x 84mm (H), which provides a 35% space savings versus typical contactors. Additionally, its power consumption of 3.75 Watts is about 50% less and its low noise characteristic of 70dB is about 30% quieter than those contactors. The electrical Life is 80k operations for an AC resistive load of 40A @ 440VAC (N.O. Contact), or 100k operations if switching a DC resistive load of 5A @ 110 VDC (N.O. Contact).

The G7Z is available in 12VDC or 24VDC coils and maintains a dielectric withstand of 4,000 VAC between coil and contacts. It can also be panel or DIN Rail mounted.
