Electromagnetic Actuator with State Recognition Feature Used in Fuze

Abstract

Electromagnetic actuator can realize safety state restoration function of fuze via switching on or off. In order to make fuze or safety and arming device easily obtain the information of relief safety procedure accomplishment and security status recovery of electromagnetic actuator, a new electromagnetic actuator with state recognition feature used in fuze is proposed, in which the triggering unit and signal output unit are added. The working principle of electromagnetic actuator is synchronized with switching process of signal output unit. The fuze or safety and arming device can obtain the safety state information by means of signal acquisition. The test results show that the operation state of this new electromagnetic actuator is stable, the signal output is reliable, and the best-case response time is 3 ms.
