The Omron H7ER-NV1-BH Counter enhances tachometer visibility with a bright backlit LCD, making it ideal for dark or enclosed equipment panels. It supports 1 kHz and 10 kHz input speeds for measuring slow to very high RPM levels accurately. The 5-digit display accommodates extended readings, while voltage input compatibility (4.5β30 VDC) simplifies integration with encoders. Designed to resist shock, vibration, static, and electrical noise, it maintains stable performance in industrial environments. Manufactured by Omron and included in Omron Counter products, this tachometer is part of the Omron H7ER Series.
