Pepperl+Fuchs SU18/16/40a/110/115/126a | Fiber‑Optic Sensor Amplifier | Push-Pull Output | Red LED | M8 / DIN‑Rail Options
Overview
The Pepperl+Fuchs SU18/16/40a/110/115/126a is a fiber-optic sensor amplifier available in compact M8 or DIN-rail versions. Designed for use with plastic and glass fiber optic cables, it pairs with tiny fiber heads to deliver detection ranges up to ±450 mm. Equipped with a modulated visible red LED transmitter (~660 nm), push‑pull (4‑in‑1) output logic, and self‑diagnostic feedback, it’s ideal for high‑precision detection in space‑constrained automation applications.
Key Features
-
Sensor Range (depending on fiber): Up to 150 mm (diffuse); 450 mm (thru‑beam)
-
Light Source: Modulated visible red LED, ~660 nm; ambient light tolerance up to 10,000 lux(
-
Output Type: Push‑pull (4‑in‑1), switchable NPN/PNP, light‑on/dark‑on logic
-
Operating Voltage: 10 – 30 V DC, ripple ≤ 10 %
-
Supply Current: ≤ 30 mA (no‑load)
-
Max Output Current: 100 mA resistive load
-
Self-Diagnostics: LEDs show power, output, short‑circuit, and undervoltage events
-
Response Modes: Teach‑in key plus slide switches for light/dark mode, timer (off‑delay/on-delay), and response mode selection (normal, high-speed, high-resolution)
-
Approvals: MTTFd = 690 a, Mission Time = 20 a, Diagnostic Coverage (DC) = 0 %
Applications
-
Compact detection in medical or sensor arrays
-
Thru‑beam and diffuse sensing in tight industrial installations
-
Cleanroom or high-tech assembly lines
-
Integration with Pepperl+Fuchs KLR/KLE plastic/glass fiber optics
-
OEM control systems requiring modular sensing proximity
Why Choose the SU18/16/40a/110/115/126a Series
-
Flexible sensing distances—up to 150 mm diffuse or 450 mm thru‑beam
-
Compact design with M8 or DIN‑rail options for versatile mounting
-
Full push‑pull output supports NPN or PNP and light/dark switching
-
Self‑diagnostic LEDs and Teach‑in controls simplify setup and monitoring
-
Selectable response modes and timer functions optimize performance to match application speed and precision
-
High reliability with safety‑rated MTTFd and operational diagnostics
