Adafruit ADA-413 24 V Push-Pull Solenoid

The Adafruit ADA-413 is a 24 V DC push-pull solenoid with a 40 mm long body and a captive armature that includes a return spring. It suits makers and engineers building linear actuation into robotics, locking mechanisms or automated fixtures. Four M3 threaded holes on the base allow secure mounting on metric grids. The coil draws roughly 250 mA when energised.

Upgrade from simple push or pull units

Many low-cost solenoids offer only a single directional force and lack a captive armature, so the slug can fall out during operation. This model provides both push and pull action from opposite ends and the spring returns the armature automatically when power is removed. The jump is worth it when a design needs reliable two-way motion without external return mechanisms or when the armature must stay captured inside the coil.

Limits of direct 24 V DC drive

Operating the solenoid directly from a logic-level output is not possible because the coil requires a current surge that exceeds typical microcontroller pin limits. A power transistor and flyback diode are mandatory to switch the load safely. The supply must deliver enough current for the 250 mA inrush; small 9 V batteries cannot sustain it. Voltage below 24 V reduces force but the device functions down to 9 V DC.

Questions about this item

How do I mount the 40 mm solenoid body?

The base has four M3 threaded holes so you can bolt it directly to a panel or bracket with standard M3 screws.

What circuit parts are required to drive this solenoid from a microcontroller?

You need a power transistor and a flyback diode; the coil draws roughly 250 mA at 24 V so the transistor must handle that current.

Does the return spring ever need replacement?

The captive armature includes a built-in return spring rated for the life of the solenoid; no user-serviceable spring replacement is expected.
