The Sommer 7028 is a 2-wire frame photo eye designed for professional installation. Important: Installation must be performed only by qualified experts. The device must be installed at a height of less than 300 mm and requires precise 90-degree alignment between the transmitter (TX) and receiver (RX) to function correctly.
Technical Data
- Recommended Range: 0 to 6 m
- Range Limit: 8 m
- Temperature Range: -20°C to 60°C
- Connection: 2-wire
- Protection Type: IP 67
- Max Cable Cross-section: 0.5 mm²
- Installation Height:< 300 mm
Scope of Supply
The package includes the transmitter (TX) and receiver (RX) units, mounting covers, Euro terminals, screws, and mounting sheets depending on the specific kit version (7028V000/V001, S10929-00001, S10230-00001).
Installation
There are three primary mounting variants depending on the frame type and thickness:
- Variant 1: Standard wall mounting using the provided back cover.
- Variant 2: Mounting using the provided mounting sheet.
- Variant 3: Flush mounting into the frame.
Refer to the plate thickness table for hole diameter requirements: 1 mm plate requires a 13 mm hole; 2-3 mm plates require a 13-13.5 mm hole.
Alignment
Proper alignment is critical for operation. The transmitter (TX) and receiver (RX) must be positioned directly opposite each other at a 90-degree angle. Ensure the installation height is strictly below 300 mm from the ground.
Wiring
The system uses a 2-wire connection. Connect the TX and RX units to the control unit as shown in the wiring diagram. Ensure wires are stripped correctly (10 mm) before insertion into the terminals.
Practical help
Common problems
Photo eye not detecting
Ensure the transmitter and receiver are aligned at exactly 90 degrees and the installation height is below 300 mm.
