Buzzer magnets with a locking function. The direction of movement of the plunging core is determined by the polarity of the control. In the retracted state on the pull side, the core remains unpowered. The extension movement is supported by a compression or return spring. Flexible in application, as the lifting movement is free of stops on one side and is only limited by the size of the device. Connection type: wire (approximately 21 cm). Insulation class B (130 °C). Designed for 100% duty cycle. Force specifications apply to the warm coil; force values for a cold coil are approximately +25% (depending on the model). Ideal for price-sensitive industrial applications such as energy-saving locking mechanisms.
