The Future of Miniature Automation: Meet the IAI ELECYLINDER® Wire Cylinder

In today's manufacturing environment, engineers are constantly challenged to design machines that are smaller, faster, cleaner, and smarter. Traditional pneumatic cylinders have served the industry well for decades; however, as the demand for greater precision, higher productivity, longer service life, more compact equipment, and improved energy efficiency, their limitations become increasingly visible.
IAI has addressed this challenge with one of its most innovative products: the ELECYLINDER® Wire Cylinder (EC-WER1 Rod Type and EC-WEGR2 Gripper Type). This technology introduces a completely new way of achieving linear motion while delivering the precision and programmability of electric actuators in an incredibly compact package.
Why a Wire Cylinder?
Conventional electric actuators place the motor directly on the moving mechanism, increasing the size and weight of the end effector.
The IAI Wire Cylinder takes a different approach.
Instead of mounting the motor on the actuator, the motor, encoder, and controller are relocated into a separate Wire Controller, connected by a flexible control wire. This unique design provides several important advantages:
Extremely compact actuator size
Reduced moving mass
Better thermal isolation from the work area
Greater design flexibility
Easier integration into tight spaces
Tiny Size—Big Performance
The Wire Cylinder is designed for applications where every millimeter counts.
EC-WER1 Rod Type
Body width: only 13 mm
Weight:
32 g (10 mm stroke)
48 g (20 mm stroke)
EC-WEGR2 Gripper
Body width: 25 mm
Weight: only 43 g
These dimensions are comparable to Ø6–Ø8 mm pneumatic cylinders, yet they provide the advantages of a fully programmable electric actuator.
The Benefits of Electric Motion
Unlike pneumatic cylinders that depend on air pressure, flow controls, and mechanical adjustments, the Wire Cylinder allows users to digitally configure:
Position
Speed
Acceleration
Deceleration
Push force
Grip force
All parameters can be adjusted numerically using the IAI Teaching Pendant or PC software, making machine setup faster, more repeatable, and easier to optimize.
Intelligent Push and Grip Detection
One of the most powerful features of the Wire Cylinder is its ability to verify contact automatically.
Instead of relying on external sensors or pressure switches, users can define a target push position and force. The controller then determines whether:
The required force has been achieved
The workpiece is present
The operation completed successfully
The actuator is idling without contacting a part
This built-in intelligence improves process reliability while reducing sensor count and wiring complexity.
Perfect for Multi-Axis Robotic Tools
Because the actuator itself is extremely lightweight, several Wire Cylinders can be mounted directly on a robot end-of-arm tool.
Applications include:
Precision pick-and-place
Electronic component assembly
Quartz handling
Semiconductor equipment
Medical device assembly
Small-part gripping
Laboratory automation
IAI even supports installations with up to 16 Wire Controllers positioned close together, making complex multi-axis tooling remarkably compact.
Lower Maintenance Than Pneumatics
Traditional pneumatic systems require:
Air tubing
Solenoid valves
Flow controls
Regulators
Air preparation
Leak maintenance
The Wire Cylinder eliminates most of these components.
No compressed air means:
Reduced energy consumption
Cleaner installations
Lower maintenance
Improved reliability
Simpler machine design
The actuator also includes an Automatic Servo OFF function, which turns the servo off automatically after positioning is complete and reactivates it only when the next motion command is received, helping reduce power consumption.
Built for Long Service Life
Despite its compact size, the Wire Cylinder is designed for demanding industrial environments.
Key specifications include:
Position repeatability down to ±0.01 mm (pressure operation)
Operation life of 10 million reciprocating motions
CE and RoHS compliance
IP20 protection
Built-in stepper motor technology
These features make it suitable for continuous production environments requiring precision and repeatability.
Flexible Integration Options
The Wire Cylinder supports multiple control configurations, including:
NPN or optional PNP I/O
Battery-less absolute encoder
Wireless teaching
RCON-EC field network connection
Three-position operation mode
Configurable cable exit directions
This flexibility allows machine builders to integrate the actuator into virtually any automation platform.
Ideal Applications
The IAI ELECYLINDER® Wire Cylinder is especially well suited for:
Electronics manufacturing
Semiconductor equipment
Battery production
Medical device assembly
Optical component handling
Laboratory automation
Precision robotic end effectors
Compact assembly machines
Whenever space is limited and precision matters, the Wire Cylinder offers an attractive alternative to miniature pneumatic cylinders.
Why Choose IAI?
For fives decades, IAI has led the industry in electric actuator technology.
The ELECYLINDER® Wire Cylinder represents another step toward fully electric automation by combining miniature size with intelligent motion control.
Compared to conventional pneumatic cylinders, users gain:
Higher positioning accuracy
Programmable motion profiles
Adjustable push and grip forces
Reduced energy costs
Simplified maintenance
Cleaner machine designs
Greater process repeatability
Final Thoughts
As manufacturers continue replacing pneumatic systems with electric motion, products like the IAI ELECYLINDER® Wire Cylinder make it possible to automate even the smallest mechanisms without sacrificing precision or flexibility.
Its innovative remote-drive architecture, intelligent force control, and ultra-compact design make it one of the most exciting solutions available today for next-generation automation equipment.
If your next machine demands miniature size, precision, and intelligent motion control, the IAI Wire Cylinder deserves a closer look
