OMRON E32 / E3X fiber optic sensors
In electronic component inspection, diffuse reflective and thru-beam optics each have their place: diffuse reflective for checking opaque objects, thru-beam for long distances or transparent objects. The OMRON E32 series offers the E32-D22L diffuse reflective fiber (IP67, long distance, ø3 mm cylinder) and the E32-T11 thru-beam fiber (M4 thread, up to 3,750 mm), combined with E3X amplifiers — the E3X-F21 (PNP, simple type) and E3X-HD11 (NPN, Smart Tuning, 20 μs high speed).
Specifications
| Model | Type | Key specifications |
|---|---|---|
| E32-D22L | Fiber unit (diffuse reflective) | ø3 mm cylinder, long distance, top-view in-line, IP67, nickel-plated brass housing, 2 m fiber |
| E32-T11 | Fiber unit (thru-beam) | M4 thread, R4 bend radius, IP67, sensing distance up to 3,750 mm, 2 m fiber |
| E3X-F21 | Amplifier (PNP) | Pre-wired, 200 μs response, simple operation for packaging lines |
| E3X-HD11 | Amplifier (NPN) | Smart Tuning, 20 μs high speed / GIGA mode, IP50, red LED |
| E3X-HD11-2M | Amplifier (NPN, 2 m cable) | Long-cable version of E3X-HD11, flexible wiring, automatic compensation for aging and dirt |
Key features
- Diffuse reflective + thru-beam: E32-D22L for in-place checks of opaque objects; E32-T11 thru-beam up to 3,750 mm for long-distance or transparent object detection.
- Smart Tuning (E3X-HD11): automatically sets the threshold, without repeated manual adjustment, shortening setup time.
- GIGA high-speed mode, 20 μs: E3X-HD11 response as fast as 20 μs for part counting on high-speed lines.
- Automatic aging compensation: E3X-HD11-2M compensates for aging and contamination, reducing maintenance.
- IP67 fiber units: E32-D22L / E32-T11 are IP67 for oil mist and wet environments.
- PNP / NPN options: E3X-F21 (PNP) / E3X-HD11 (NPN) to suit different PLC systems.
Applications
- Electronic component presence / position confirmation
- Object detection on packaging machines (E3X-F21)
- Part counting on high-speed lines
- Long-distance detection of transparent objects / bottles
- M4 thread mounting in tight spaces
- Equipment upgrades and maintenance replacement
