Keyence LS-5501 Built-In Display Type Controller

The Keyence LS-5501 is a built-in display type controller engineered for precision laser displacement measurement within the LS-5000 series. This unit integrates sensor parameter configuration, real-time measurement display, and tolerance-based quality control in a single chassis. The 7-level LCD tolerance check output provides immediate visual feedback on part conformance, while the dedicated green LED indicator at the scanning head confirms laser emission status. ## Technical Specifications Display & Measurement • Display range: −99.99995 to 999.99995 mm or −0.99999" to 9.99999" • Minimum displayable unit: 0.05 µm • 7-level LCD tolerance check indicator Input Interfaces • Program selection input: Non-voltage (contact/solid-state) • Laser stop/remote input: Non-voltage (contact/solid-state) • Timing, reset, and auto-zero inputs: Non-voltage (contact/solid-state) Output Interfaces • RS-232C: Measurement data and control output • 7-level comparator output: 100 mA maximum at 40 V maximum • Analog voltage output (optional I/O board): ±10 V, 100 Ω impedance • BCD output: Available as optional module Power & Environment • Input voltage: 85 to 264 VAC, 50/60 Hz • Power consumption: 85 VA maximum • Ambient temperature: 0 to +40 °C (32 to 104 °F) • Relative humidity: 35 to 85 % RH (non-condensing) • Weight: Approximately 3.7 kg ## Key Features • Multi-level comparator output enables simultaneous monitoring across seven zones for product categorization and multi-stage quality gates • RS-232C communication for automated data logging and equipment integration • Non-voltage input topology provides flexibility in timing synchronization across diverse production line architectures • Optional analog and BCD outputs expand integration pathways for legacy and modern control systems ## Typical Applications Precision dimensional inspection, automated quality control, thickness measurement, surface profiling, and multi-zone product sorting in manufacturing environments. ## Compatibility & Integration Designed for use with Keyence LS-5041 sensor head and the LS-5000 series ecosystem. Optional I/O boards extend measurement and output capabilities. This model is discontinued; LS-9000 series optical micrometers are recommended as successors.
