Solenoid factors in machine automation

Process and machine automation range from one-off basic functions to sequence the complex. In these situations where these processes involve rotary or linear motion, solenoids are one of the best types of actuation devices when it comes to ease of use, simple installation, cost, and size.

Solenoids are used in a wide variety of applications. Some of the common applications for rotary solenoids include copiers, ticket machines, brakes, pinch rollers, machine tools, film processors, automatic tellers, textile machinery, defibrillators, IC insertion machines, and circuit breakers, and counters. Among the most common applications for linear solenoids are electronic typewriters, disk drive locks, film processors, coin changers, interposers, pumps, door locks, copiers, brakes, and vending machines.

Here are some of the main functions that solenoids are ideally suited for as follows-


The life span of dc solenoids is as much as 100 million cycles of workout and the delivery of repeatable, predictable performance, solenoids deliver uncompromising reliability.

Simplified Control

Solenoids are pulsed devices and have minimal components, making them ideal for digital control, resulting in higher reliability and faster cycling with fewer interfaces.


The electrical operation and snap-acting response of solenoids benefit part rejection processes where electronic interfacing involving a photo sensor is needed.


Medical equipment often involves tubes that carry body fluids The flow regulation on these tubes must be accurately controlled. A linear solenoid, for example, has variable positioning capability and can be used to pinch the tube smoothly and precisely to the operator’s demand. By using a solenoid this way, valves and other types of connecting apparatuses that could pose leakage or contamination threats are eliminated.

Latch and Lock

Long life, reliability, compact size, and low cost are some of the major reasons solenoids are becoming increasingly in demand for use in many different types of locking applications such as missile systems, lamp solenoids, and solenoids door lock disk drives, cash registers, and vaults doors.

Whether the solenoid is linear or rotary, it can be configured quite easily into machine designs that required a stage or platform to be latched or locked into position throughout a specific machine process.


Depending on what the specification application is a gate diverter can be used infrequently or continuously. A rotary solenoid, for example, can be used due to its actuation life rating of 100+ million.

Exceptional Torque or Force

Linear solenoids that are 2 1/4 inches long or less can provide as much as 30 pounds in force as well as 100 pounds in torque. So, tubular solenoids are used in a linear solenoid.


There is a wide range of positioning applications from simple ratcheting devices to variable precise positioning that can make use of rotary or linear solenoids.

Variable Positioning

Rotary solenoid applications and linear solenoid applications are both capable of offering variable positioning.

High Speed

It only takes milliseconds for a solenoid to be actuated. The velocity of a solenoid can also be controlled, which provides noiseless, smooth actuation.

Small Size

Whether a small frontal area, minimum volume, or low profile is needed, solenoids are ideal. Compared to motors, the work they deliver per cubic inch is much greater.

Last word and conclusion

Solenoids are very flexible and are used in a wide range of applications and industries. They are useful in any situation where controlled motion is necessary, such as holding, rotating, positioning, clamping, latching, locking, pulling, pushing, and lifting. Whether your system includes rotary or linear operations, there is a good chance that there is a solenoid that can meet your specific application requirements.
