Marantec 97246 M8-705 Photo Eye Safety Sensor Kit
The Marantec 97246 M8-705 photo eye kit is a replacement hardwired safety sensor set for Marantec residential garage door operators. Photo eyes are one of the most important safety parts on a garage door opener because they watch the door opening while the door is closing. When the beam is interrupted, the opener should stop or reverse instead of continuing down. This kit is used when a sensor lens is cracked, the LED will not stay aligned, the wiring terminals are damaged, or the opener will only close when the wall button is held. Because Marantec used several sensor names over the years, this item is often searched under M8-705, M4-705, ML-705, and older sensor kit numbers. Use the opener model and original sensor reference to confirm fitment before replacing safety equipment.

Technician Note
Match the part number, operator model, and product family before ordering. For safety-related or wiring-related parts, confirm the original installation and parts diagram instead of relying on appearance alone.
Before Ordering
- Confirm the Marantec part number printed on the old part or shown in the parts diagram.
- Match the opener model, product generation, and accessory type.
- Check frequency, wiring style, safety-device requirements, and included components where applicable.
- Review whether the old number has been superseded or is only a related search number.
- Use a qualified garage door technician for unsafe door movement, electrical diagnosis, or control-board wiring.
Important Ordering Warnings
- Do not bypass, remove, or defeat garage door safety sensors.
- Check wiring and alignment before assuming both sensors have failed.
Professional Advisory
Garage door and gate products should be installed and serviced with all required safety devices in place. If wiring, safety sensor diagnosis, or opener troubleshooting is uncertain, have the system checked by a qualified technician.
Product Questions and Answers
Is Marantec 97246 the same as the M8-705 sensor kit?

Will this work on all Marantec garage door openers?
It is commonly listed for Marantec residential openers, including many Synergy and M-Line models, but older installations should be checked by model and original sensor type.
What symptoms point to bad photo eyes?
Common symptoms include the door reversing while closing, the opener light flashing, the door only closing while the wall button is held, or sensor LEDs that will not align.
Can I bypass the photo eyes?
No. Photo eyes are required safety devices. Do not bypass them; repair the wiring, alignment, or sensor kit instead.
Does this kit include both sides?
Marantec 97246 is normally sold as a sensor kit with both the sending and receiving photo eyes, but always check the package contents on the order page.
