Control Type Page
Reliable, field-adjustable tubular motors for projects that need simple wired control and stable upper/lower end positions.
How it works
How a Mechanical Limit Motor Works
Adjustment screws
Installer adjusts upper and lower stop positions mechanically.
Cam and micro-switch
The cam mechanism triggers the stop positions without software programming.
No programming required
Useful for simple wired systems and distributor stock models.

Best use
When Mechanical Limit Is the Best Choice
Cost-sensitive projects
Practical for standard wired systems and repeat distributor demand.
Simple installation
Good where installers are familiar with mechanical adjustment.
Stable standard models
Useful when smart control is not required and field adjustment is preferred.
Alternatives
When Electronic Limit Is Better
Comparison
Mechanical, Electronic, Receiver and Manual Override
| Type | Best fit | Caution |
|---|---|---|
| Mechanical limit | Simple wired or receiver systems | Requires correct field adjustment. |
| Electronic limit | Projects needing electronic setting | Confirm model and controller compatibility. |
| Built-in receiver | RF remote control projects | Confirm transmitter, frequency and pairing process. |
| Manual override | Power-failure operation for shutters and awnings | Confirm head, crank and bracket access. |

FAQ
Mechanical Limit Motor FAQ
Is mechanical limit reliable?
Yes, it is a practical and widely used limit method when the motor is correctly sized and installed with compatible accessories.
How are upper and lower limits adjusted?
Mechanical limit motors use adjustment screws with a cam and micro-switch mechanism to set upper and lower stop positions.
Can mechanical limit motors work with remote control?
Yes. Models such as YYGL35R, YYGL45R and YYGL59R combine mechanical limits with a built-in receiver.
Which models include manual override?
YYGL45M, YYGL45MR, YYGL59M and YYGL59MR include manual override configurations.
How do I choose the correct motor?
Confirm application, tube, load, torque, voltage, control method, accessory set and whether manual override is required.
Need confirmed motor selection?
Send application, tube size, load, voltage, control method, quantity and target market. Walter Motor can check the motor family, accessories and OEM configuration before sample or batch order.
