  XLC Series Raceclocks
Full-Featured Sports Timing Clocks with Super-Bright LED Digits.
Battery powered, CE-certified for 90-264 Vac, 50/60 Hz AC power.


XLC Series Raceclocks by Electro-Numerics set the international standard for full-featured sports timers with all-solid state reliability and no moving parts. The display is provided by sunlight legible ultra-bright LEDs with a 90 wide viewing angle. The units can be ordered for single or dual-sided viewing, with 5 or 6 digits, and in three digit heights: 102, 152 or 229 mm (4", 6" or 9"). A rule of thumb is that viewing distance n meters is 0.5 times digit height in millimeters, or viewing distance in feet is 40 times digit height in inches. Please see our Raceclock dimensions.

Internal sealed batteries provide 10 hours of continuous operation on a single battery charge. A battery charge indicator is included.

CE certified for international use, XLC Series Raceclocks feature an external battery charger suitable for 90 to 264 Vac, 50/60 Hz AC power. They are available with different power cords for use in different countries. CE certification covers safety according to IEC requirements, electromagnetic immunity (EMC), and electromagnetic emissions (EMI). Please see our XLC Declaration of Conformity.

The race clocks feature a rugged aluminum case with a carrying handle and a built-in keypad to select timing modes, time-of-day, and preset times. Remote operation is provided by an optional remote keypad, remote control unit, and remote display. Please see our Raceclock Accessories page. Options also include a tripod and a carrying case for each size Raceclock.


Other race clocks:  Intended for North America, our XL Series Raceclocks feature an internal 120 Vac, 60 Hz battery charger and a US power cord. Our LM Series Raceclocks feature yellow, reflective, electromagnetic flip digit in heights of 102, 152 or 229 mm (4", 6" or 9"). Also see our low-cost LED MileMarker Raceclocks, which are intended for use at mile marker locations along the race course.
