3B Scientific NETlog Infrared Photo Gate, 75mm Barrier Spacing, 0.1 ms Time Resolution

Infrared photo gate for triggering the 3B NETlog unit or a digital counter. For time measurements in experiments on free fall, motion on a track or pendulum oscillations and for counting pulses. It can be operated in internal mode using the built-in infra-red light source or in external mode with the aid of a laser pointer, which needs to be obtained separately. It then acts as a wide-range light barrier, allowing it to be used at sporting events, for example. The gate includes an operational indicator light, stand rod with screw thread, M6 bolt for attachment to a roller track and connector lead with 8 pin mini DIN plugs. Barrier spacing: 75mm. Rise time: less than 500 ns. Spatial resolution: less than 1 mm. Time resolution: 0.1 ms.
