Speed switch / overspeed switch / speed monitor
The electronic speed switches (overspeed switches) of the EGS 40 series monitor up to four programmable speed ranges (overspeed, underspeed and standstill) with high switching accuracy even at low speeds. If one of the programmed speeds is exceeded or is too low, the respective switching output of the speed monitor switches. The speed switches thus contribute to system and personal protection.
The speed switches are mainly used on crane motors, in mining and in rolling mills.
Safe
The electronic speed switches (overspeed switches) of the EGS 40 series ensure reliable speed monitoring even under extreme ambient conditions.
