Product Overview
The E3X-ZV11 is the NPN output variant of Omron's E3X-ZV 1-channel Smart Fiber Amplifier family — a cost-optimized amplifier with twin 7-segment display, smart-tuning teach, and a 50 µs response time that makes it the right pick for high-speed counting applications (up to 10 kHz event rates). The amplifier accepts any E32-series fiber-optic cable on the front face and supports through-beam, diffuse, and retro-reflective modes. The NPN open-collector output sinks current (up to 100 mA at 30 VDC) to drive a PLC input, relay coil, or counter directly. The 2 m pre-wired PVC cable terminates at stripped-and-tinned leads (brown = +V, blue = 0 V, black = output, white = not connected).
E3X-ZV vs E3X-HD: when to pick which
The E3X-ZV is positioned below the E3X-HD in the E3X amplifier hierarchy: ZV = cost-optimized 1-channel tier (1 output only), HD = full-functionality 1-channel tier (also 1 output but with more tuning modes), MZV = 2-channel tier (2 outputs + 2 inputs). The ZV has the smart-tuning teach, twin display, and E32 fiber compatibility shared with HD; what the ZV does NOT have: (1) external trigger input (only on E3X-MZV@2 series); (2) high-sensitivity mode and APC (auto-power-control, only on HD); (3) EtherCAT/CompoNet communication adapter support (the HD supports the E3X-ECT, the ZV does not).
50 µs response time — where this matters
The 50 µs (0.05 ms) response time gives a maximum counting rate of 10,000 pulses/sec on a 50 % duty-cycle — twice the speed of the older E3X-NA amplifier, and on par with dedicated high-speed photoelectric counters. Real-world uses: small-part counting on a high-speed filling line (5,000+ parts/min), label-edge detection at high conveyor speeds (10 m/s), pin-marking registration at high production rates (300 ppm stamping line), PCB component presence verification at placement-head rates (50,000+ placements/hr). The output pulse width is also 50 µs minimum — narrow pulses must be widened by the receiving PLC or counter.
Smart tuning, 1-channel operation, and external wiring
Like all E3X-ZV amplifiers, the ZV11 supports one-button smart tuning with the SET button — point the fiber at the target, press SET; point at the background, press SET; the threshold is auto-set at the midpoint. The Light-ON / Dark-ON mode is selected via a separate push button on the front face. The amplifier has 1 output (NPN, sinking) on the pre-wired cable's black conductor. There is no separate external trigger input on the 1-channel ZV@ models — if you need external trigger (e.g. conveyor-encoder synchronization), step up to the 2-channel E3X-MZV@2 series. There is no EtherCAT or CompoNet communication support on any ZV variant.

Buying Checklist
- Pick E3X-ZV11 for NPN pre-wired 2 m fiber amplifier with 50 µs ultra-fast response for high-speed counting
- Pick E3X-ZV41 for the PNP version of this amplifier — pick for PNP/sourcing PLCs
- Pick E3X-HD11 if you need NPN with high-sensitivity mode and EtherCAT support — pick for networked installations
- Pick E3X-HD8 if you prefer an M8 connector instead of pre-wired cable
- Pick E3X-MZV11 if you need 2 channels in one amplifier for panel-space savings
- Pick the E32-T@ thru-beam fiber for 5-100 mm through-beam detection

FAQ for E3X-ZV11
What's the difference between E3X-ZV11 and E3X-HD11?
Both are 1-channel smart fiber amplifiers with twin display, but at different price/feature tiers: E3X-HD11 is the higher-functionality tier (~30 % more expensive) with added features: (a) high-sensitivity mode for sub-millimetre object detection; (b) APC (auto-power-control) for compensation when fiber ages; (c) EtherCAT/CompoNet communication adapter support (E3X-ECT); (d) external trigger input (some HD variants); (e) additional tuning modes like 7-step fine-tuning.
Can the E3X-ZV11 do 10 kHz counting?
Yes — the 50 µs response time (1/0.05 ms = 20 kHz theoretical max) handles 10 kHz actual event counting reliably with margin. Note that the 50 µs is the response time of the analog front-end; the digital processing adds ~100 µs of decision time, giving a practical 200 µs decision time per event.
What's the difference between E3X-ZV11 and E3X-MZV11?
E3X-ZV11 (this SKU) is 1-channel with 1 output and no external input. E3X-MZV11 is 2-channel with 2 outputs, allowing two fiber-optic cables per amplifier (saves panel space when you have 2 adjacent detection points). The MZV11 also has 2 external inputs (on the E3X-MZV@2 variants) for trigger / synchronization.
Can the E3X-ZV11 be controlled from a PLC over a network?
No — the E3X-ZV11 does not support any fieldbus communication adapter; the amplifier only has the pre-wired NPN output to communicate with a controller. For networked control where you want to read incident light level, set threshold remotely, and run diagnostics over Ethernet, the E3X-HD@ series supports the E3X-ECT communication unit (up to 16 amplifiers on EtherCAT), the E3X-CRT (CompoNet), or the E3X-SRT (Slave Terminal CompoNet).
