Procurement teams shortlist H7ER-N with Omron SMPS 24V 10A, Omron H7Ec N and Omron Photoelectric Sensors E3T Series, aligning budget approvals, warranty terms, and multisite availability for smoother rollout across plants.
Omron H7ER-N Counter
The Omron H7ER-N Counter delivers precise tachometer performance with a fast 1 kHz input capability and 0.5 ms response for stable rotational speed monitoring. Its 4-digit LCD with 8.6 mm characters ensures excellent visibility, while the no-voltage input method offers simple integration with switches and sensors. Designed for stable industrial use, it provides strong resistance to noise, vibration, shock, and static electricity. With an IP66-rated front and wide operating temperature range, it suits harsh environments. Manufactured by Omron and available under Omron Counter products, this model belongs to the Omron H7ER Series.
