Surface-Mount Stroboscopes with Certificate of Calibration
Integrate these stroboscopes into fast-moving lines to check quality. They’re often used to inspect printed labels, rolled metal, and packaging. Channels on three sides allow you to attach them to T-slotted framing and other equipment. They shine bright and uniform pulsing light at moving parts to make them appear slower. This helps your machine vision camera and other digital inspection equipment identify defects. Connect them to sensors to trigger flashes at precise intervals in systems where timing and coordination are crucial. For synchronized usage along your line, you can daisy-chain multiple together. All come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.
For visibility in all conditions, they have three light intensity settings. The lowest is often used for highly reflective surfaces, and the highest works well on dark and high-contrast materials. For quick changes between processes, their memory stores up to 10 light patterns.

Tips measure the rotational speed of shafts and other spinning objects. Tips for flat-end surfaces are often used with pulleys and circular saws. They have a concave surface to fit flush over bumps, such as screw heads. Tips for shafts with center hole are cone-shaped, so they’ll fit the inner diameter of different hole sizes.
Speed wheels measure the length and speed of conveyor belts, bolts of fabric, and material on spools. They have a grooved edge to fit over wire, cable, and cords.

High-Accuracy Panel-Mount Tachometers with Certificate of Calibration
Accurate to within ±0.001% of reading, these tachometers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. Install in a convenient location and measure speed remotely using a sensor (sold separately). Use the buttons on the front panel to program the unit.
Proximity sensor detects moving metal objects, such as gear teeth and fan blades and can be used in dirty and wet environments. Maximum measuring distance is 0.2" from a 1/2" minimum size metal target.
Magnetic sensor has a maximum measuring distance of 0.005" from a 0.1" minimum size ferrous metal target.
Optical sensor performs best in clean environments and works at up to a 45° angle from reflective tape.

High-Accuracy Panel-Mount Tachometers
Accurate to within ±0.005% of reading. Install this tachometer in a convenient location and measure speed remotely using a sensor (sold separately). It updates twice per second when the reading exceeds 120 rpm.
Proximity sensor detects moving metal objects, such as gear teeth and fan blades and can be used in dirty and wet environments. Maximum measuring distance is 0.2" from a 1/2" minimum size metal target.
Magnetic sensor has a maximum measuring distance of 0.005" from a 0.1" minimum size ferrous metal target.
Optical sensor performs best in clean environments and works at up to a 45° angle from reflective tape.

Tachometers/Hour Meters for Gas Powered Engines
Continuously measure the speed and running time of your engine to monitor its performance and detect mechanical issues early. These meters can be programmed based on engine run time to light up for maintenance reminders, such as oil changes, filter replacements, and inspections. Wrap the signal wire four to five times around your spark plug to secure it in place. They’re battery powered, so they will start showing readings as soon as you turn on the engine. It adjusts to nine different engine types for accurate readings. They’re rated IP67, so they won’t get damaged from dust and water.

Panel-Mount Tachometers
Install in a convenient location and measure speed remotely using a sensor (sold separately).
Sensors generate a light beam across a 0.8" wide gap. When a rotating object enters this gap, the beam is broken.

Speed-Monitoring Switches
Detect unwanted slowdowns in a rotary shaft that could cause machine damage and downtime. These switches are often used on drivetrains, conveyors, and other power-driven components. They come with a pulser disc, which you’ll need to attach to the shaft by drilling and tapping a hole. Once mounted, the disc rotates with the shaft and creates magnetic signals that the switch senses. When the speed falls below a set point, the switch will trigger an alarm or turn off the system.
Switches are UL listed and rated NEC Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G. They have an explosion-proof housing and are also rated NEMA 4X for washdown and corrosion protection.
