Pasco PS-3703 Wireless Smart Gate Dynamics System

The PASCO PS‑3703 Wireless Smart Gate Dynamics System is a versatile photogate timing setup. It wirelessly connects to computers for recording, displaying, and analyzing motion data—capturing time, speed, and velocity metrics with precision. The unit mounts effortlessly to the PASCO Dynamics Track via included brackets. It also ships with picket fences that attach directly to Dynamics Carts. Built around dual infrared beams spaced 1.5 cm apart, the Smart Gate achieves a timing resolution of 3 µs and a minimum block time of 1.5 ms. This makes it ideal for studying pendulums, carts, projectiles, and other dynamic systems.

It features Bluetooth and USB connectivity, a rechargeable Li‑Po battery, and a compact footprint (~10.5 × 7.0 × 3.0 cm, approx. 90 g). All components are packaged together—one Smart Gate, a photogate head, bracket set, and two picket fences—providing a ready-to-use experimental tool for physics education and lab-based dynamics analysis.
