Keyence IL-100 Sensor | 100mm Mid-Range Head

Keyence IL-100 CMOS Laser Sensor Head

Product Introduction

The Keyence IL-100 belongs to the IL series of CMOS laser displacement sensors. This reflective-type sensor head uses triangulation technology for precise distance measurement. Its 100 mm standoff suits applications that need generous clearance. The IL-100 measures targets between 75 and 130 mm with linearity of ±0.15% of full scale. Furthermore, a 4 µm repeatability ensures stable readings for quality control tasks. The sensor head requires an IL series amplifier unit for power and signal processing.

Technical Specifications

Optical Performance

The Keyence IL-100 operates with a red semiconductor laser at 655 nm wavelength. This visible light source simplifies alignment during installation. Laser output is rated at 560 µW, placing the device within Class 2 safety limits. Specifically, the spot diameter at the reference distance measures approximately 400 × 1,350 µm, enabling detection of small features at longer standoff.

Measurement Capabilities

The sensor head covers a measurement range of 75 to 130 mm from the reference distance. Highest linearity of ±0.15% of F.S. applies within the 80 to 120 mm segment. Meanwhile, repeatability reaches 4 µm when sampling at 1 ms with a standard white diffuse target. The sampling rate is selectable among 0.33, 1, 2, and 5 ms across four levels.

Temperature Stability

Temperature characteristics are rated at 0.06% of F.S./°C. Additionally, the unit maintains stable output across the operating temperature range from -10 to +50 °C.

Mechanical and Environmental Parameters

Physical Construction

The housing material combines PBT for the main case and SUS304 stainless steel for metal parts. A glass lens cover protects the optical components. Moreover, the cable uses PVC insulation for durability in industrial settings. The Keyence IL-100 weighs approximately 75 g, making it suitable for mounting on moving fixtures.

Protection Rating

The enclosure carries an IP67 rating for dust and water resistance. This protection allows operation in environments where coolant spray or dust may be present. Besides, pollution degree 3 certification covers typical industrial conditions.

Operating Conditions

Ambient temperature range extends from -10 to +50 °C without condensation or freezing. Relative humidity tolerance spans 35 to 85% RH with no condensation permitted. For ambient light, the sensor tolerates incandescent illumination up to 5,000 lux. Vibration resistance meets 10 to 55 Hz standards with 1.5 mm double amplitude across all three axes for two hours each.

Installation Guide

Amplifier Compatibility

The IL-100 sensor head requires connection to an IL series amplifier unit such as the IL-1000 or IL-1550. First, verify that the amplifier is powered off before making connections. Next, insert the sensor head cable into the designated port on the amplifier unit. The amplifier provides both power and signal conversion for the sensor head.

Mounting Position

Position the sensor head so the target surface sits near the 100 mm reference distance. For best linearity results, maintain target placement within the 80 to 120 mm window. The long standoff offers extra clearance for fixtures and tooling. Use appropriate mounting brackets to secure the head against vibration.

Target Considerations

The Keyence IL-100 performs optimally with diffuse reflective targets. However, extremely shiny or transparent surfaces may require adjustment of the sampling rate or target positioning. Therefore, test the setup with actual production parts before full deployment.

FAQ

What amplifier unit works with the IL-100?

The IL-100 connects exclusively to IL series amplifier units. Compatible models include the IL-1000 (DIN-rail mount) and the IL-1550 (panel mount). These amplifiers supply power and convert sensor signals to analog or digital outputs.

Can the IL-100 detect transparent objects?

Standard reflective sensors struggle with transparent materials. However, the IL-100 may work with some translucent targets if the user adjusts the sampling rate and threshold settings on the amplifier. For glass or clear film, consider a dedicated transparent-object sensor instead.

What is the smallest detectable feature with this sensor?

The 400 × 1,350 µm spot diameter defines the minimum target size. Features smaller than the spot may not produce reliable readings. For finer resolution at shorter range, consider the IL-030 sensor head with its narrower beam profile.

Does the IL-100 require maintenance?

The sensor head has no user-serviceable parts inside. However, periodic cleaning of the glass lens cover prevents measurement drift from dust or oil accumulation. Use a soft cloth with appropriate optical cleaning solution. Furthermore, inspect the cable for damage during routine maintenance checks.

What is the difference between the IL-100 and IL-065?

Both models share the same CMOS technology and IL series amplifier compatibility. However, the IL-100 offers a longer 100 mm reference distance with a 75 to 130 mm range. Meanwhile, the IL-065 provides a 65 mm reference distance and a narrower 55 to 105 mm measurement span. The choice depends on the available mounting space and required standoff distance.
