A "Solenoid Pull Push Type Electromagnet" with the specifications of DC 5V-12V and a force range of 0.4N to 8N can be described as follows:

Operating Voltage: This solenoid is designed to operate with a range of direct current (DC) voltages, specifically between 5 volts (5V) and 12 volts (12V). This voltage range allows for flexibility in adapting the solenoid to different power supply options.

Operation Mode: It is a "Pull-Push Type" solenoid, which means it has the capability to both pull and push when energized. In its default state, it is normally closed, indicating that it tends to remain in the closed or resting position when not powered.

Force Range: This solenoid is capable of exerting a force in a range from 0.4 Newtons (N) to 8 Newtons (N). The specific force within this range may vary depending on factors such as the voltage applied and the design of the solenoid.

Versatility: The ability to operate within a voltage range and the dual pull-push functionality make this solenoid versatile and suitable for various applications that require controlled linear motion in both directions.
