877 type electromagnetic counterDetailed product description：

Working principle and purpose:

The 877 electromagnetic counter is used to record the cumulative number of electrical pulse signals. It can be used as a digital display instrument in secondary instruments and is widely used for various electrical pulse counting in industries such as petroleum, chemical, textile, machinery, mining, national defense, agriculture, food, printing, etc. After the electrical signal is input into the counter, a suction force is generated in the electromagnet, which drives the armature to drive the escapement mechanism and drives the digital wheel to rotate for decimal counting.
