Answer:
The FAAC 844 R is delivered without a pinion to accommodate FAAC Z12, Z16, or Z20 rack pinions or chain conversion sprockets based on weight and speed requirements. It pairs with inductive metal sheet limit switches and operates with built-in electronics or external FAAC 844T three-phase control boards.
The FAAC 844 R 380V MC 3PH is shipped from the factory without a pre-fitted drive pinion, allowing site engineers and installers to tailor the final mechanical drive configuration to site requirements:
- Modular Rack Pinions: Supports genuine FAAC Z12, Z16, and Z20 steel rack pinions, matching heavy-duty steel gear racks for weights between 1,000 kg and 2,200 kg.
- Chain Transmission: Can be adapted using FAAC chain drive sprockets for commercial applications requiring chain links rather than gear rack rails.
- Limit Switches: Features an integrated inductive limit switch system that interfaces with steel trip plates mounted directly along the rack rail.
- Control Electronics: Built with onboard control provisions and fully compatible with the dedicated FAAC 844T three-phase external microprocessor control panel, which provides motor reversing contactors and electronic braking.
- Safety Accessories: Directly interfaces with active Category 3 resistive safety edges and external directional infrared photobeams across opening spans up to 50 meters.
