Electro-Mechanical Timers


Electro-mechanical timers function as On delay, off delay, interval timers, or repeat cycle devices. This device regulates specific machine functions, such as filling or actuating a part of the system, such as a conveyor. In addition, an electro-mechanical timer is characteristically long-lived. If your application for a timer requires less space or where a non-fixed (variable) time range is required, then look at our Electronic timer products.

Eagle Signal electro-mechanical timers are very popular for applications that do not require extremely fast duty cycles or reset actions. Select the proper electro-mechanical timer from the Eagle Signal portfolio based on the time interval requirements of your application. Characteristics common to all models are:

  • Simplicity of Operation – user-adjustable setpoint with a knob and a simple clock-like dial.
  • Operate in Harsh Power Environments – electro-mechanical timers are virtually immune to EMI, brownouts, and blackouts and withstand many power surges.
  • Heavy Duty Construction - years of operation continue to prove the extended maintenance-free life in dirty, dusty, damp, hot, and cold environments.
  • Simple Programming - no switch programming required. Timer works the way you expect it to work.
  • Long Service Life - highly reliable. Exact or similar replacements available for an extensive installed base.

Commonly Asked Questions About Electro-Mechanical Timers

What are electro-mechanical timers?

Electro-mechanical timers consist of electrical and mechanical components and often feature an electric motor that drives one or more gears. They typically accept electric or electronic inputs to operate a mechanical output such as rotating wheels or knobs. The ruggedness and simple efficiency of an Eagle Signal electro-mechanical timer are what makes them ideal for applications in spaces such as:

  • Pump controls
  • Food processing
  • Material handling
  • Packaging
  • Plastics manufacturing
  • Irrigation timers

How do electro-mechanical timers work?

In electro-mechanical timers, a synchronous motor turns the cam through the switch contacts. Sometimes, a friction clutch can be found between the cam and the gear train. Electro-mechanical timers must be adjusted manually.

What are the types of electro-mechanical timers?

The five main types of electro-mechanical timers include on-delay, off-delay, internal delay, recycle (percentage), and one-shot timers.
