An infinitely variable multi-directional linear motion solenoid actuator (10) for use on printed circuit boards (12). The solenoid actuator includes wire coils (14) wound onto a bobbin (16) and a moveable magnetic armature (18) passing through a central bore (20) of the body. The armature is responsive to current passing through the coils to produce infinitely variable and reversible motion. Support posts (22) passing through the bobbin are used for electrical connection between the coils and the circuit board, as well as for mounting the actuator to the circuit board. The support posts may have solder heads on one end for surface mounting to the board, and may have plain heads on an opposed end for alternative through-hole mounting. A vacuum pick area (56) may be formed on one or both sides of the bobbin body to facilitate automated handling of the actuator.
