LiftMaster OES-EDSR Optical Edge Sensor Kit
The LiftMaster OES-EDSR is an optical edge sensor kit for compatible LiftMaster Optical Edge System safety edges. It provides the infrared sensing components used inside the rubber edge assembly.
What This Part Does
This sensor kit is commonly used when servicing a monitored OES edge where the rubber edge remains usable but the internal optical sensing components need replacement or installation.
Compatible With
This LiftMaster OES component is commonly used with select LiftMaster commercial door operator installations that require monitored entrapment protection. Compatibility depends on door type, edge profile, operator safety input, and the installed OES system components.
- Select LiftMaster OES sectional door edge systems
- Select LiftMaster OES rolling door edge systems
- OES-SD16 and OES-SD24 sectional door edge kit families when matching service parts are required
- OES-RD16 rolling door edge kit family when matching service parts are required
- OES-RD50 rolling door edge component installations
- Commercial door operators with compatible monitored edge inputs
Important Compatibility Notes
- Use sectional door OES parts only on compatible sectional door applications.
- Use rolling door OES parts only on compatible rolling door applications.
- Do not mix edge profiles, sensor kits, mounting kits, or wiring components unless the LiftMaster OES instructions support the combination.
- The commercial operator must support the required monitored edge input for the installation.
- All safety devices should be tested after installation before the door is returned to service.

Also Known As / Related Part Numbers
This part may be searched under related LiftMaster OES names or nearby component numbers. Related numbers are not always interchangeable, especially when the door type or edge length is different.
Technician Note
Match the OES component to the door type and the original installation, not just the LiftMaster brand name. Sectional door edges, rolling door edges, sensor kits, coil cords, junction boxes, and mounting kits work together as a monitored safety system. A similar-looking component may not be correct if the edge profile, door style, wiring, or operator input is different.
Before Ordering, Confirm
- Original LiftMaster OES part number or kit number
- Door type: sectional overhead door or rolling door/grille
- Required edge length or field-cut edge material
- Existing optical sensor, junction box, coil cord, and mounting hardware condition
- Commercial operator model and monitored edge input requirements
- Whether the job requires one replacement component or a complete OES kit
Professional Advisory
Optical edge systems are safety-related components on commercial doors. Installation, wiring, adjustment, and testing should be performed by a qualified commercial door technician. Do not bypass a monitored safety edge or operate a commercial door with missing, damaged, or untested entrapment protection.
Important Ordering Warnings
- Do not assume sectional and rolling door OES parts interchange.
- Do not use rubber edge material alone when the installation requires sensors, wiring, and monitoring components.
- If the operator displays a monitored edge fault, inspect wiring, sensor alignment, coil cord, and junction box before replacing parts.
- Confirm package contents because some OES listings are complete kits while others are individual replacement components.
Questions & Answers
What does the OES-EDSR kit replace?
The OES-EDSR kit replaces or supplies the optical sensing components used inside compatible LiftMaster OES rubber door edge systems.
Is OES-EDSR the same as the rubber edge?
No. OES-EDSR is the optical sensor kit. The rubber edge material, mounting hardware, junction box, and coil cord may be separate depending on the installation.
Can OES-EDSR be used with both sectional and rolling door edges?
It may be used with select LiftMaster OES sectional and rolling door edge systems when the edge profile and installation parts are compatible.
What symptoms can point to a bad optical edge sensor?
A failed or misaligned sensor may cause monitored edge faults, failure to close, intermittent reversal, or a safety input error on a compatible commercial operator.
What should be checked before replacing OES-EDSR?
Check the rubber edge condition, sensor alignment, wiring, junction box, coil cord, and operator error codes before replacing the sensor kit.
