Description
The Panasonic (formerly SUNX) EX-13EA is an ultra-slim through-beam photoelectric sensor from the EX-10/13 series — the thinnest class of industrial photoelectric sensors (just 3.5 mm thick). It consists of a separate Emitter (E) and Receiver (R) pair that detects objects when the light beam between them is interrupted.
- EX-13EA → NPN Normally Open (NO) output, 1 m sensing range (through-beam), 1 m cable (pre-wired), 12–24 V DC 3-wire.
- Housing: 12 × 20 × 3.5 mm (W×H×D approx.) — fits in extremely tight grooves, slit guides, or between close-spaced machine parts where standard Ø4–Ø18 mm barrel sensors cannot go.
- “A” suffix = NPN NO; “P” suffix (EX-13EP) = PNP NO.
Through-beam type gives the highest immunity to dust, smoke, and target color/reflectivity — simply breaking the beam triggers it.
Key Features
- Ultra-Slim: Only 3.5 mm thick — industry’s slimmest class
- Through-Beam Design: Emitter + Receiver pair — unaffected by object color or reflectivity
- Sensing Distance: 1 m (max. guaranteed — typical EX-13 series)
- Output: NPN Open Collector NO (black wire pulls LOW when beam broken)
- Supply: 12–24 V DC (10–30 V DC)
- LED Indicators: Red RX LED (lights when beam received — goes OFF on detection)
- Mounting: M2 side/back screw holes — flush or standoff
- Country of Origin: Japan / Malaysia (Panasonic Industrial Devices)
Model & Variant Reference (EX-13 Family)
Model | Type | Output | Cable | Notes |
|---|---|---|---|---|
EX-13EA | Through-Beam (E+R pair) | NPN NO | 1 m | Most common — NPN (Asian/JIS machines) |
EX-13EP | Through-Beam (E+R pair) | PNP NO | 1 m | PNP (European/NA style sourcing) |
EX-13FA | Retro-Reflective (single body) | NPN NO | 1 m | Needs reflector — less common in EX-13 |
EX-13EB (if avail.) | Through-Beam | NPN NO | M8 connector | Quick-disconnect version |
⚠️ Important Notes:
Technical Specifications (EX-13EA — Through-Beam NPN NO, 1 m, 1 m Cable)
Parameter | Specification |
|---|---|
Model / Order Code | EX-13EA (Panasonic / SUNX EX-13 Series) |
Sensing Principle | Through-Beam (Separate Emitter + Receiver) |
Maximum Sensing Distance | 1.0 m (guaranteed — typical alignment range up to 1.2 m in clean air) |
Minimum Detectable Object | Ø 0.5 mm opaque wire/object (theoretically — practical depends on alignment) |
Output Type | NPN Open Collector (NO — Normally Open: Output LOW when beam interrupted = object detected) |
Max. Load Current | 50 mA (DC resistive) — lower than GX series — check load! |
Supply Voltage | 12–24 V DC (10–30 V DC allowable) |
Current Consumption (Rx side) | ≤ 15 mA (Emitter typically ≤ 20 mA) |
Response Time | ≤ 1 ms (both turn-ON & turn-OFF) |
Hysteresis | — (through-beam has no hysteresis in same sense — operates on beam presence/absence) |
Protection Circuitry | Reverse polarity protection, Over-current (short-circuit) protection |
Connection | 3-wire PVC cable, 1 m length (both E & R have same pinout — E ignores output wire) |
Housing Material | PBT (UL94 V-0) — Aluminum mounting bracket typically included |
Mounting | Flush or standoff via M2 screw holes (side & rear) |
Protection Rating | IP64 (splash resistant — not for high-pressure washdown) |
Operating Temp. | -25 … +55 °C (no freezing/dewing) |
Dimensions (per piece — E or R) | ~ 12 mm (W) × 20 mm (H) × 3.5 mm (D) |
Weight (Pair) | ~ 10 g (with cable) |
Standards | CE, UL (component), RoHS |
Warranty & After-Sales

Applications
- Tight Clearance Detection: Detect wafer/PCB edge, thin tab, or product passing through narrow guide rails (< 5 mm gap available).
- High-Speed Counting: Bottles/cans on high-speed filler — through-beam responds < 1 ms.
- Part Presence in Fixture: Verify small component seated before cycle start — slim profile fits in fixture slot.
- Label / Film Web Break: Detect web break on converting line (through-beam not fooled by translucent film reflection).
- Retrofit: Replace bulkier Ø4 mm / Ø6 mm barrel through-beams where space is < 4 mm wide.
