KEYENCE Expands High-Precision Sensing Portfolio with FX-MR2, FW-V25 and Versatile FU Fiber Optic Series for Global Automated Manufacturing

Industry News, July 2, 2026

OSAKA, Japan – KEYENCE Corporation, a global leader in industrial automation sensing and measurement technology, has reinforced its end-to-end precision detection solution lineup, highlighting the FX-MR2 amplifier module, FW-V25 fiber optic amplifier unit and a full suite of FU-series fiber heads including FU-E11, FU-77V, FU-77TZ, FU-77, FU-75F, FU-66Z, FU-66TZ and FU-66. The integrated product group targets micro-component inspection, narrow-space mounting, high-speed production lines and harsh industrial environments across electronics, automotive, food packaging and precision machinery sectors worldwide.

The FW-V25 serves as the core signal processing hub for the complete FU fiber optic portfolio, engineered with dual-row 3-digit LED displays and dual independent NPN open-collector control outputs to deliver stable signal conversion for both through-beam and reflective fiber probes. Equipped with adjustable chattering prevention timers ranging from 0.5s to 10s, reverse polarity and overcurrent protection circuits, the FW-V25 maintains consistent detection performance amid vibration, electrical interference and rapid workpiece transit. Its power-saving eco mode cuts power consumption to under 97mA, lowering long-term operational energy costs for mass-production factories running 24/7 shifts. Complementary to the FW-V25, the FX-MR2 multi-functional amplifier module extends system scalability, supporting bank shift input and multi-channel switching for complex multi-point inspection stations on automated assembly equipment.

KEYENCE’s FU fiber optic heads cover diversified mounting and precision detection demands, forming a complete modular matching ecosystem with the FW-V25 and FX-MR2 amplifiers:

FU-77, FU-77V, FU-77TZ Through-Beam Fiber Sensors
Adopting M4 threaded nut-style housings with 2m free-cut fiber cables and a minimum detectable object of ø0.005mm, these through-beam units excel at counting tiny electronic pins, wafer edge verification and small component passing detection. FU-77TZ features a concentrated optical axis of ø1.13mm for ultra-fine target recognition, while FU-77V optimizes light transmission stability for dusty, humid workshop conditions. The fiber cable withstands tight bending radii down to R2mm without signal attenuation, ideal for robotic grippers and moving fixture setups.
FU-66, FU-66Z, FU-66TZ Reflective Fiber Probes
Parallel dual-core reflective design delivers high signal contrast for non-contact surface detection, suitable for PCB solder joint presence check, label positioning and transparent film edge tracking. FU-66TZ’s compact M4 body fits ultra-narrow installation gaps inside injection molding molds and compact automation jigs, with wide operating temperature tolerance from -40°C to +50°C to support low-temperature warehouse and high-temperature molding production lines.
FU-75F Ultra-Thin Sleeve Fiber Head
Boasting an ultra-slender ø0.82mm sleeve section, FU-75F solves mounting bottlenecks in densely arranged connector assemblies and miniature device internal inspection, where conventional fiber sensors cannot penetrate confined spaces. It provides reliable detection for micro spring contacts and miniature chip conveyance without interfering with surrounding mechanical structures.
FU-E11 General-Purpose Fiber Unit
A cost-effective universal reflective fiber model balancing detection range and compact size, widely deployed for standard workpiece presence detection in packaging, logistics sorting and household appliance assembly processes, lowering total sensing hardware investment for mid-volume production lines.

Industry automation engineers note that the unified KEYENCE sensing stack eliminates compatibility debugging work between amplifiers and fiber probes, shortening equipment development cycles for machine builders serving European, Southeast Asian and North American manufacturing markets. All models comply with UL and CSA industrial safety standards, supporting global deployment without regional hardware modification.

Against the backdrop of rising demand for micro-precision manufacturing driven by semiconductor, EV component and consumer electronics industries, KEYENCE’s combined FX-MR2, FW-V25 and FU fiber series addresses two core pain points for manufacturers: stable detection of sub-millimeter targets and flexible installation in space-restricted automated equipment. Field tests at automotive electronics assembly plants show the integrated sensing system reduces false detection rates by over 85% compared to generic fiber sensor combinations, directly boosting production yield and cutting unplanned downtime.

KEYENCE global product marketing director stated that the full FU fiber and amplifier lineup will maintain steady global stock supply throughout 2026, with localized technical support teams providing on-site parameter tuning and application scheme design for system integrators and end manufacturers across all major industrial regions. Moving forward, the brand will further optimize digital communication compatibility of FW-V25 and FX-MR2 to seamlessly connect with PLC, HMI and factory MES systems, advancing the integration of high-precision fiber sensing into full digital smart factory architectures.
