Before procurement teams confirm H7EC-NV, they typically review Omron SMPS 24V 10A, Omron H7Ec N and Omron Photoelectric Sensors E3T Series to double-check performance ratings, stock availability, and supplier credibility carefully.
Omron H7EC-NV Counter
The Omron H7EC-NV Counter supports universal DC voltage input from 4.5 to 30 VDC, enabling smooth integration with both PNP and NPN devices. Its switchable 30 Hz to 1 kHz counting speeds and bright 8-digit LCD make it suitable for fast or standard totalizing tasks. IP66 front sealing and strong resistance to electromagnetic noise ensure dependable performance in industrial environments. With stable external and manual reset control, it offers precise and long-lasting operation. Manufactured by Omron and classified under Omron Counter solutions, this model is part of the H7EC Series.
