Speed Control Products


Speedshield’s original product solutions were based on speed control technology for industrial and automotive applications. Speedshield’s limiters are true dynamic speed limiters adapting to environment terrain and load.

  • Pedal reference voltage and pedal ground inputs
  • Three pedal attenuation signals configurable to attenuate signal to pedal reference voltage (max 5V) or pedal isolated group (0V)

SLA Speed Limiter

Speedshield’s SLA speed limiter system is suitable for cable throttle vehicles. Unlike most conventional speed limiters, where fuel or spark is cut to prevent power and drive, Speedshield first converts the cable throttle system into an electronic pedal and actuator controlled throttle system allowing for full smooth electronic speed and acceleration control.

The result is a fully computer controlled speed limiting system that doesn’t harm the vehicle drive train, and can interact with Speedshield zoning accessories to provide variable speed control in different zones.
