CSL 34 EMA

Electromagnetic Actuator - Clockstopper

The CSL 34 EMA Electro Magnetic Actuator is a high-power electromagnetic system designed to stop and hold certain clockwork fuze mechanisms, allowing controlled and deliberate render-safe procedures to be carried out. By applying a sustained magnetic field, the EMA enables operators to intervene safely in scenarios involving mechanical fuze timing systems.

​

The kit is supplied as a two-barrow system to support field deployment. One wheeled barrow houses the high-capacity battery pack, while the second carries the electromagnet assembly itself. This separation improves handling, positioning, and system stability during operation.

​

The EMA is operated via a hard-wired remote control with an integrated cable reel, allowing the operator to maintain a safe distance from the target while retaining precise control. A portable generator unit is also included to extend operating time during prolonged tasks or when external power sources are unavailable.

Key Features:

  • High-power electromagnet for stopping clockwork fuze mechanisms

  • Enables controlled render safe procedures

  • Two-barrow configuration for field mobility

  • High-capacity battery power system

  • Hard-wired remote control with cable reel

  • Portable generator unit for extended operation

  • Designed for professional EOD use

Typical Applications:

  • Render safe procedures involving mechanical clockwork fuzes

  • EOD operations requiring sustained magnetic intervention

  • Controlled intervention during timed fuze neutralisation

  • Field operations requiring mobile electromagnetic systems
