OMRON ZFV series intelligent visual sensor

Product Overview and Safety Standards

Product positioning

Ultra high speed CCD intelligent visual sensor, no programming required, LCD visual operation.

Version: Ver. 2.0, added functions such as image logging, measurement data reset, and communication settings.

Safety and usage taboos

Non safety grade products cannot be used for personal safety protection.

Environment: 0~50 ℃, 35%~85% RH, no corrosion/dust/strong electromagnetic.

Power supply: DC24V ± 10%, reverse connection is prohibited, strong and weak electricity are separated and wired.

Maintenance: Use air to clean the lens, and do not use acetone/alcohol.

Hardware composition and specifications

1. Core components

Key parameters of component model

Sensor head ZFV-SR10 (narrow field of view) with a distance of 34-49mm and a field of view of 5 × 4.6~9 × 8.3mm

ZFV-SR50 (wide field of view) distance 38~194mm, field of view 10 × 9.2~50 × 46mm

Amplifier unit ZFV-A10/A15 NPN/PNP, simple type: pattern/brightness detection

ZFV‑A20/A25 NPN/PNP， Standard type: Full function testing

2. Electrical and Performance

Processing speed: high-speed 4ms/standard 8ms/high-precision 12ms

Resolution: Maximum 468 × 432

Bank quantity: 8 groups, expandable to 128 groups

Input/output: TRIG trigger, TEACH teaching, BANK switching ENABLE/ERROR/OUTPUT

Installation and wiring

Installation method

DIN rail installation (35mm), panel installation (with ZS-XPM1 bracket).

The amplifier must be installed vertically to ensure heat dissipation.

I/O wiring definition

Brown: 24V; Blue: GND; Black: OUTPUT; Orange: ENABLE; Light Blue: ERROR

Yellow: TEACH; Powder: TRIG; Gray/Green/Red: BANK1~3

Group installation

Up to 5 amplifiers can be linked together, with shared triggering and comprehensive judgment output.

The image is transmitted from right to left and triggered by the rightmost host for unified input.

Operation and Setting

Three working modes

MENU mode: demonstration, parameters Bank、 System settings.

ADJ mode: Adjust the judgment threshold (related value/area/width, etc.).

RUN mode: Run detection, output results, support display switching.

Teaching demonstration types (8 types)

PATTERN (SEARCH/MATCH): Shape presence/matching degree

BRIGHT: Brightness/Scratches

Area: Area

WIDTH: Width

POSITION: Position

COUNT: Counting

CHARA1/CHARA2: Character Whole/Missing Character Detection

Key setting items

Measurement speed: FINE/NORMAL/HIGH SPEED

Trigger mode: TRIG synchronous/Continuation continuous

Output: OK ON/NG ON, single pulse, delay

ECO mode: Screen off after 3 minutes of inactivity (default ON)

Group linkage (Gang Mounting)

rule

Maximum connection: 5 units

Trigger/Teach/Enable: Only valid on the host

Output: Can choose between comprehensive judgment (ALL) or individual output (EACH)

data flow

Image: Right → Left

Trigger: Right → Left

Output/Enable: Left → Right

Malfunctions and anomalies

Common exceptions

No image: lens not connected, light source turned off, focusing error

Not outputting: mode not RUN, trigger not inputted, output polarity reversed

Teaching failure: workpiece out of field of view, improper area, too bright/too dark

error code

HEAD IS NOT CONNECTED: Sensor head not connected

TEACHING FAILED: Teaching failed

BANK DATA ERROR: Bank data exception

Key issues

Question 1: What is the core difference between the ZFV simplified model (A10/A15) and the standard model (A20/A25)?

answer:

Simple type (A10/A15): Only supports two types of detection: PATTERN and BRIGHT, suitable for basic presence/absence/brightness judgment.

Standard type (A20/A25): Supports all 8 types of detection (area, width, position, counting, characters, etc.), with complete functionality.

Question 2: How many groups can ZFV collaborate with at most? How to configure triggering and output during linkage?

answer:

Up to 5 amplifiers can be linked together.

The triggering, teaching, and enabling signals are only valid for the rightmost host.

The output can be set as:

ALL: All unit results are synthesized and output uniformly by the host.

EACH: Each unit outputs results separately.

Question 3: How to save ZFV parameters? What will happen if the power is not saved?

answer:

The parameters are automatically saved when switching to RUN mode or when external TEACH teaching is successful.

If the power is directly cut off after modifying the MENU/ADJ mode, all changes (including teaching) will be lost and the state before the power outage will be restored.
