KEYENCE IL Series: CMOS Multi-Function Analog Laser Sensor
Introducing the Intelligent Sensor IL Series, a new CMOS Multi-Function Analog Laser Sensor.
Key Features and Introduction
The IL Series is a new CMOS Multi-Function Analog Laser Sensor that offers a balance of low cost and high performance. It is designed for a variety of applications requiring precise measurement.
Key measurement capabilities include:
- Height / Height Difference
- Warpage
- Thickness / Width
- Positioning
- Vibration
- Count
Intelligent, Rugged, Easy Design Philosophy
The IL Series is designed with three core principles:
- Intelligent: Achieves high precision through state-of-the-art technology and functions developed for high-accuracy measurement instruments.
- Rugged: Features a robust structure designed for use in harsh environments, with components like die-cast metal for the optical base (SUS304) enhancing strength and protection.
- Easy: Offers excellent usability for quick and stable measurements without complex adjustments or settings.
The series offers low cost and high performance, focusing on advanced functions for on-site operations.
High-Precision Head + Multi-Function Amplifier
The IL Series features a high-precision head and a multi-function amplifier, combining higher stability with an all-in-one design.
The amplifier automatically controls laser power based on target reflectivity, enabling stable measurements on various materials from black rubber to highly reflective metal. Application-specific functions are integrated into the compact amplifier for streamlined communication with process control systems.
Rugged Head Structure
The head structure is redesigned for ruggedness, utilizing die-cast metal for the IP67-rated optical base, which is made of die-cast SUS304 for added strength and protection.
Compact Head Design + Easy Mounting
The IL Series boasts the smallest head housing in its class, achieved through a unique aspherical lens. The head weighs a mere 60g (for the IL-030 model). The sensor head cable is designed as a robot cable, offering high cycle service life, making it ideal for robotics and high-cycle applications.
The Hi-flex cable is rated for 20 million cycles, can withstand a load of 250g, and has a bending radius of R50 mm at a rate of 30 bends per minute.
IL Series Sensor Heads

|---|---|---|---|---|
| IL-100 | 100 mm (3.94") | 75 to 130 mm (2.95" to 5.12") | 2 µm (0.08 Mil) | 10 µm (0.39 Mil) |
| IL-065 | 65 mm (2.56") | 55 to 105 mm (2.17" to 4.13") | 2 µm (0.08 Mil) | 4 µm (0.16 Mil) |
| IL-030 | 30 mm (1.18") | 20 to 45 mm (0.79" to 1.77") | 1 µm (0.04 Mil) | 2 µm (0.08 Mil) |
Multi-Function Amplifier with All-in-One Design
The amplifier unit provides versatile connectivity and advanced functions.
New Mode: Thickness Calibration Function
A new mode allows for a simplified 3-step thickness calibration process, reducing setup time compared to conventional methods where each sensor head required individual calibration.
Ambient Light Elimination Function
The IL Series automatically activates an ambient light elimination function when the sampling cycle is set to 2 ms or 5 ms, reducing interference from ambient light.
Calculation Functions
Addition Mode
Used for thickness or width measurements.
Subtraction Mode
Used for measuring height differences or tilt.
Function Choices
NPN/PNP Output Selection
Supports both NPN and PNP outputs, which are set upon initial power-up and can be changed later. Judgments are output as HIGH, GO, or LOW.
Analog Output Selection
Five types of analog outputs can be selected:
| Setting Value | Description |
|---|---|
| OFF | Not output |
| 0-5V | Analog output after the judgment value is converted to the range from 0 to 5 V. |
| ±5V | Analog output after the judgment value is converted to the range of ±5 V. |
| 1-5V | Analog output after the judgment value is converted to the range from 1 to 5 V. |
| 4-20mA | Analog output after the judgment value is converted to the range from 4 to 20 mA. |
Settings can be changed.
Bank Function
Allows registration of up to four patterns of specific settings (e.g., HIGH setting value, LOW setting value, shift value, analog output scaling) for easy switching between measurement target changeovers.
Mounting Method Options
Both panel mount and DIN-rail mount units are available for the amplifier.
Communication Units
- DL-RB1A (BCD Output Unit): Used for retrieving numerical data from the IL Series to an external device as digital data. A single unit can retrieve data from up to 8 IL Series display units via BCD.
- DL-RS1A (RS-232C Communication Unit): Used for outputting digital data to an external device via RS-232C signals. It can also be used to externally program the amplifiers.
Applications
The IL Series is suitable for a wide range of industrial applications:
Height difference measurements of a plastic extrusion
Provides constant monitoring by measuring height with two sensors simultaneously, then calculating the height difference. Reliable detection is possible even if the product type or color changes.
Warpage detection in ceramic boards
The compact sensor head allows for multiple point measurements on small boards. External calculation of measurement data enables simultaneous measurement of positioning and warpage.
Thickness/width measurements of a plaster board
Easy setup using the thickness calibration mode. Setup man-hours are reduced, allowing for easy product changeovers.
Packaging material counting
Reliable counts are achieved by detecting rising edges, even for targets with significant shape scatter.
Accuracy checks on an automotive door assembly
Simultaneous measurement of multiple points allows for evaluation of assembly accuracy. Reliable detection is possible regardless of body color.
Positional control of welding beads
Through external calculation of height data, the device detects weld seam positions. Welding accuracy can be improved via measurement data feedback to the welder.
Heat processing inspection of cans
Observing the expansion displacement of a can after heat processing allows for evaluation of the process. Reliable differentiation is possible even with color changes in the cans.
Vibration measurements of a washing machine
Easy mounting due to a compact and lightweight head. Recording analog output with a data logger enables defect analysis and research.
Differentiation of different types of plastic components
Reliable differentiation of small, highly variable parts is possible. External changeover of up to 4 patterns is supported via the bank function.
Stacker device counts and stacking disturbances
The IL Series counts items on a conveyor and detects non-contact stacking disturbances. Reliable detection is achieved regardless of target color changes.
Wire winding process
Prevents irregular winding by monitoring the traverser position. Feedback control is possible by measuring the volume wound onto the bobbin simultaneously.
Deflection measurements in a PC board
Non-contact, reliable detection of board displacements during strength inspections. A maximum sampling speed of 0.33 ms allows for real-time displacement measurements.
Detection of stage inclination prior to furnace transportation
Calculates stage inclination by measuring multiple points before furnace transfer. Correcting inclination ensures consistent temperature control.
Behavior detection in an operational unit
Measures the behavior of each unit within a device. The small head footprint allows installation in compact spaces, even after machinery setup.
Misalignment measurement and presence detection of a wafer/glass in a cassette
Measures presence and protrusion of glass in a cassette. Stable detection is possible even with positional misalignments by utilizing analog processing.
Measuring the height of a chip after bonding
Measures board height pre-bonding and chip height post-mounting, allowing control of post-processing suction and dispenser nozzles.
