Hybrid steppers take position, precisely
In a frame measuring only 20mm square, the new DSM2032H and DSM2035H hybrid stepping motors from Geeplus offer 200 steps per revolution, making them ideal for applications requiring precise position.
For safety applications, Geeplus provides a range of electromagnets which develop an attraction force when an electric current is applied to the device.
The most common use would be in fire doors which, in the event of an alarm being triggered or power failure, the magnet would release the door to close off the area.
Also available are HMER (holding magnets with electrical release) devices which combine the properties of both.
Permanent magnets provide excitation to hold the mating part without external power being applied and an excitation pulse is applied with reverse polarity to counter the permanent magnetic field and release the mating part. Request a free brochure from Geeplus ...
