Sensa-Bloc II™

  • Indicates occupancy of an entire block by sensing current drawn by locomotive or lighted car.
  • No soldering required
  • DCC compatible

Sensa-Bloc II™ provides the sensing that is needed to control all the track side signals.

Sensa-Bloc II™ uses quick plug-in connectors for fast and easy installation to track and throttle. It detects current flow in a given block of track. It can be used for triggering flashing grade crossings, controlling aspect signals, and showing that a given block is occupied by turning on an indicator positioned on a control panel. For more control, there is a potentiometer mounted for adjusting the sensitivity so there are no false indications.
