r-tec Photocell
The photocell can detect an interrupted beam across a passage. Whether the door stops or reverses depends on the connected control board, wiring and settings of the completed installation. These product sheets do not establish a universal installation obligation for every door or barrier.
Model and connection scope
- The IR20 sheet shows 12–24 V DC supply, NO/NC contact options and sensitivity adjustment.
- MF-A and BT180 sheets list 15 m distance; this is not a documented IR20 range.
- The BT180 sheet shows a battery transmitter and a 12/24 V AC/DC receiver.
Read the current diagrams for both the selected photocell and control board to confirm compatibility and the safety function when the beam is interrupted.

How is the r-tec safety photocell (IR20) connected and aligned?
The IR20 sheet shows 12–24 V DC supply, NO/NC contact options and sensitivity adjustment. It does not state a 15 m range or 12/24 V AC supply for IR20; those values must not be copied from BT180 or MF-A. Verify transmitter-receiver placement and the control-board input against the selected model's wiring diagram.
