A magnetic motion sensor that monitors the rotational axis speed of mechanical devices, energy-saving and does not require a power supply!!
It is a magnetic motion sensor that monitors the operating speeds of belt conveyors, cranes, crushers, etc., and activates an internal switch when the speed of the machine shaft reaches the set value. The speed switch mechanically opens and closes the switch using the induced torque generated by the rotation of a permanent magnet, making it unnecessary to have a power supply and easy to maintain. 【Features】 ● No power supply required The switch operates by mechanically detecting the rotational speed. ● No maintenance required Continuous operation for long periods is possible without lubrication or inspection. ● Sturdy and highly durable Over 30,000 units delivered guarantee high quality. ● Diverse lineup There are various models available, including drive roller type (ESRW type), flange type (ESRK type), stationary type (ESRB type), low-speed type (ESRL type), dust explosion-proof type (ESRDP type), and factory pressure-resistant explosion-proof type (ESRM type). *For more details, please download the catalog or contact us.
