Buzzers NEF30-BIP and NEF30-BUZZ.
The NEF30 buzzers are intended for building in standardized Ø30.5mm holes – drilled in various types of control and signal equipment, or directly into bodies of machines and equipment.
Buzzers are produced in two versions: with continuous sound (NEF30-BUZZ) and with intermittent, pulse sound (NEF30-BIP). Likewise lamps and indicators of NEF30 series, the buzzers work under any voltage within the 24-230V AC/DC range.
