TAG-HEUER photocells are very reliable and accurate, immune to sunlight, reflection and difficult climatic effects.
The items on this page are only available for Dutch residents.
Ref. HL 2-31
Infrared photocell with reflector, range 20 meters. Built in power sources and adjustable duration of output impulse. Two LED indicators for battery condition and correct alignment. Mounting on tripoids or on supports ref. HL 4. Not recommended if the moving body (for instance a car) can cause reflection.
Ref. HL 2-35
Infrared photocell, separate transmitter and receiver, range 40 or 80 meters. Built in power sources and adjustable duration of output impulse. LED indicators for battery condition and correct alignment. Mounting on tripoids or on supports ref. HL 4-3. Recommended for professional use with distances in excess of 20 meters.
Ref. HL 2-32
Double infrared photocell (HL 2-35) with 2 synchronized transmitters and 2 independent receivers for optimal reliability. The 2 outputs are insulated by optocoupler to give one impulse by whichever beam is cut first. Range 80 meters. Recommended for professional use needing a back-up system. Confirms to FIS timing rules.
Ref. HL 2-34
Double infrared photocell for timekeeping in athletics, range 12 meters. Composed of 2 synchronized photocells. Both beams (separated by 20 cm) must be interrupted to get an impulse. Two LED indicators for battery condition and correct alignment. Mounting on tripoids.
Ref. HL 990
6-digit spectator display, digits are 15 cm (7-segment electromagnetic), size 108x23x13 cm. Low power consumpion. Needs 12 V power supply (not included). Can be connected to a Chronoprinter. Has an internal clock and remote control pad allowing the main timing functions.
