IL-S025 CMOS Laser Displacement Sensor Head
Brand: Keyence | Model: IL-S025 | Series: IL Series
The Keyence IL-S025 is an ultra-compact reflective CMOS laser displacement sensor head. It uses laser triangulation for short-range measurement. The reference distance is 25 mm. The measurement range is 20 to 30 mm. It connects to an IL series amplifier unit. No built-in communication port exists on the head. This sensor suits tight spaces and fast inline inspection.
Core selling point: 1 µm repeatability with a 0.33 ms fastest sampling rate. It delivers stable data for small part measurement, profile checking, and position feedback.

Installation Guide
- Mount the IL-S025 at the 25 mm reference distance.
- Keep the target inside 20 to 30 mm for best linearity.
- Angle the head to avoid direct mirror reflection.
- Use the IL series amplifier unit for power and signal output.
- Route cables away from motors, drives, and high-current lines.
- Tighten the mounting bracket to reduce vibration drift.
Debugging and Maintenance
- Check the spot position on the target before zeroing.
- Set sampling time to match the production cycle.
- Clean the front window with soft lens paper and alcohol.
- Do not touch the lens with bare hands.
- Verify repeatability with a standard white diffuse target.
- Replace damaged cables before they affect data stability.
Compatibility
The Keyence IL-S025 works only with IL series amplifier units. It has no built-in communication port. It does not support standalone protocols. All power, output, and expansion functions come from the IL amplifier. This head fits existing IL systems and replacement projects.
Certifications
- Laser Class 2 per IEC 60825-1.
- FDA CDRH Part 1040.10 compliance.
- IP67 protection rating.
Packing List
- 1 x Keyence IL-S025 sensor head
- 1 x protective packing box
- 1 x quick verification record from Oiltech Controls
Warranty and Shipping
All products include a 12-month warranty. We ship by FedEx, UPS, and DHL. Tracking is provided after dispatch. Contact us for stock checks and lead times.
Typical Applications
- Small part height and thickness measurement.
- Inline profile checking on automated lines.
- Position feedback for pick-and-place heads.
- Gap, step, and surface runout inspection.
- Obsolete IL system replacement and repair.
Diagnostic Capability
The IL-S025 sends raw displacement data to the IL amplifier. The amplifier handles judgment, scaling, and alarm output. Users can monitor received light intensity and measurement stability. This helps find target tilt, surface color change, or cable noise. Fast sampling supports short-cycle diagnostics.
