Product Detailed Description
Working Principle
A push-pull linear actuator functions by transforming electrical energy into linear mechanical motion. Electromagnetic variants, including solenoids, generate a magnetic field upon coil energization, thereby causing a plunger to move either inward (pull) or outward (push). Conversely, in motor-driven linear actuators, a DC or stepper motor drives a lead screw or ball screw, thereby converting rotary motion into linear displacement.
The actuator’s movement direction is determined by polarity, current direction, or motor rotation, thereby enabling precise pushing and pulling of loads.

✅ FAQ
Q1: How does a push-pull linear actuator differ from a solenoid?
A solenoid is a specific kind of push-pull actuator, characterized by a short stroke and rapid response; in contrast, motor-driven actuators provide longer strokes and greater positioning precision.
Q2: Can a push-pull linear actuator maintain its position when not powered?
Certain designs incorporate mechanical locking mechanisms or self-locking screws; solenoids typically necessitate continuous power, unless they are of the latching variety.
Q3: What voltage options are available?
Standard options encompass 12V DC, 24V DC, and voltages tailored to specific application needs.
Q4: How should I select the appropriate actuator?
Crucial considerations encompass force, stroke length, duty cycle, speed, and environmental factors.
