Speed Controllers

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 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

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

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 OMDC-250 Series is a variable speed DC motor controller with adjustable IR compensation, line compensation, 150% overload capacity and transient voltage protection.

The OMDC-SCR4X Series are SCR Speed Controllers that are NEMA 4X rated designed for washdown applications. Adjustable HP without jumpers or resistors and IR compensation.

The OMDC-130 Series reversing speed control is designed to provide instant reversing, quick precise stopping or rapid cycling for a wide range of DC motor applications.

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.

The OMDC-MD Series is a programmable speed controller with closed loop feedback and digital LED display for DC motors rated to 2 HP. NEMA 4x (IP66) rating.

The OMDC-65 Series DC drives are high performance Pulse Width Modulation (PWM) speed controls for 12, 24, and 36V battery powered equipment providing smooth control.

The OMDC-15DVE is a variable speed controller for small DC and universal motor applications. DC output current rating of 2 Amps, adjustable trimpot settings.

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.

OMDC-125 Series variable speed DC Motor Controls for PM, shunt wound, and universal DC motors. AC or DC powered with full wave bridge supply and 1% speed regulation.

The OMDC-MD Plus Series is a closed loop DC drive system with velocity-form PID algorithm for accurate and responsive control. Provides 4-20mA process output.
