Digital Tachometer 9999RPM Hall Sensor 8-24V

This digital tachometer measures rotational speed using an 8–24V DC power input and displays results on a 0.56-inch LED screen with a range of 10–9999 RPM. It is housed in durable plastic and designed for straightforward panel integration with defined mechanical mounting requirements. 1. Electrical operation relies on an 8–24V DC supply paired with a 5V NPN Hall effect sensor for consistent speed tracking. 2. Measurement performance delivers readings across a 10 to 9999 RPM span with ±0.1 percent accuracy on a 0.56-inch LED display. 3. Physical setup requires a 76 mm by 39.5 mm panel cutout and includes a 1-meter Hall switch cable for wiring. 4. Device compatibility extends to Hall switches, metal proximity switches, and infrared proximity switches as valid signal sources. 5. Operational alignment specifies that the sensing magnet must attach concentrically to the rotating shaft with its N-pole directed toward the sensor at a gap not exceeding 5 mm.
