Speed Sensors

The HHT41B series is compact and lightweight with a bright xenon lamp for easy operation with one hand and includes a rechargeable battery pack and NIST certification.

The HHT13 is a premium, digital, handheld laser tachometer with 32 integrated functions including counters and timers making this versatile for many applications.

The HHT12 is an economical, digital, battery-powered portable optical tachometer. The unique design allows you safely view both the target and the display at the same time.

This sensor series mounts directly to an AC or DC motor shaft to monitor speed and direction with a square wave output. NEMA 3R models are also suitable for outdoor use.

The HHT30R series with digital displays have both battery and AC powered options along with a latching trigger for hands-free operation and 6 programmable memory locations.

This series is an entire digital system that functions as four devices in one - a tachometer, counter, totalizer, and zero speed switch. It also includes an alarm relay output.

This compact, rugged series uses an integrated hall-effect sensor to directly sense rotating ferrous gear and other similar gear-type targets over a wide range of airgaps
