HL2-31 Photocell

20m span
Internal/External power supply
Easy alignment
Professional carry case

TAG Heuer's extensive experience in the development of infrared photocells has led to the production of highly reliable and precise instruments that are very stable in adverse conditions.

Infrared reflector-type photocell with an exceptional
quality/price ratio. For timing line widths of up to 20 meters.
Internal battery power as well as a plug for external power
input of 6-12 V DC. If the external power fails, the batteries assure proper operation of the photocell.

Impulse output length adjustment. Two indicator lamps (LED) provide information on battery condition and photocell signal alignment. Installation of standard photographic tripods (1/4" mount) or on HL 4 mounting brackets.

Recommended use
• This photocell satisfies the highest standards of timing
accuracy for the majority of sports applications.
• In all cases, photocells that use reflector technology for
timing sensing should not be employed whenever a risk
of reflection from the object being timed exists.
