High quality clamping electromagnet. Its supply voltage is 12V. The lifting capacity of up to 2 kg. The temperature limit reaches 130 degrees centigrade. Retention electromagnets are most often used for electric / magnetic locking of doors, flaps, and others. Use metal plates with a thickness starting from 3mm, this will ensure maximum retention force on the locking element. It is important to remove heat from the housing. The maximum force decreases as the coil temperature increases. This electromagnet will meet the expectations of even the most demanding user.
