Technical Datasheet: PEPPERL+FUCHS MLV12-54-LAS/76b/110/124

Product Type: Retroreflective Photoelectric Sensor with Laser Line (M12 Connector)

Part No.: 128098

Manufacturer Location: 68307 Mannheim, Germany

1. Product Characteristics & Application

• Sensor Type: Photoelectric Retroreflective Sensor.

• Sensing Principle: Works in combination with a reflector. This specific variant utilizes a highly visible, precise Laser Line (-LAS) to optimize alignment, target detection tracking, and micro-object edge validation.

• Housing Design: Compact rectangular die-cast zinc frame or high-integrity metal reinforced block. Features integrated through-holes for flexible machine frame alignment.

• Special Features: High resistance to ambient light, immune to cross-talk, and designed with a robust optical system capable of detecting fast-moving clear or reflective materials without false triggers.

2. Electrical Data

• Operating Voltage ($U_B$): 10…30 V DC (Class 2 Supply compliant)

• Electrical Design / Output Type:

  • Code /110: Includes a Push-Pull output (or custom active combination logic).

  • Code /124: Multi-functional configuration supporting light-on / dark-on switching choices.

• Test Input Option: Features a dedicated active diagnostic validation line (Test) mapped to pin 5 for system checkups.

• Protection Class: Protection Class II / Double Insulated (Type 1 Enclosure, UL Listed)

3. Performance & Structural Output

• Switching Output ($Q$): Push-Pull or complementary dual-stage logic line, allowing flexibility depending on network controller wiring.

• Dynamic Handling: High switching response frequency optimized for high-speed automated packaging, sorting systems, and robotic cells.

• Short-Circuit & Reverse Polarity Protection: Yes

4. Mechanical & Environmental Data

• Housing Profile: Compact block style with an integrated adjustable rotatable/angled connector base design.

• Optical Face Material: Scratch-resistant, high-grade coated glass or PMMA optical pane.

• Ambient Operating Temperature: Standard industrial environment rating.

• Ingress Protection: IP67 ruggedized sealing.

• Electrical Connection: Integrated standard 5-pin male circular M12 × 1 quick-connect thread header at the bottom base terminal.

• Item Code / Variant: 03

5. Electrical Connection & Wiring Layout

The sensor features a 5-pin assignment diagram directly mapped on the label face.

Pinout Assignment:

• Pin 1: +UB (10…30 V DC Power Supply)

• Pin 2: Not connected / Mode selector or complimentary output

• Pin 3: 0V (Ground / Common reference line)

• Pin 4: Q (Active Switching Output Signal)

• Pin 5: Test (External test function control line for sensor diagnostic checks)
