The sensor industry has also ushered in a new round of price adjustments.

"From sensors to analog chips, from passive components to connectors, the wave of price increases across electronic components in 2026 has already swept through the entire industrial chain. For downstream manufacturers, now is a critical window to reassess supply chain strategies and secure capacity ahead of time."
　　Following collective price hikes in April by major chipmakers such as MPS, TI, and NXP, the sensor sector has also entered a new round of price adjustments. STMicroelectronics and Allegro MicroSystems recently announced official price increases, reflecting how cost pressures from upstream raw materials and packaging/testing are continuously propagating down the semiconductor supply chain into automation components. Since late 2025, there have been a cumulative total of 56 price adjustment notices covering passive components, analog ICs, connectors, and upstream materials—signaling intensifying cost pressure across electronic components that will directly drive up procurement costs for automation equipment.
　　01—ST and Allegro Announce Price Increases
　　Since the beginning of 2026, the global sensor industry has faced a concentrated wave of price hikes, with leading companies including Novosense, SmartSens, onsemi, and Omron successively raising product prices. These increases span core categories such as magnetic sensors, image sensors, and industrial sensors, with price hikes ranging from 5% to 50%.
　　STMicroelectronics (ST): On March 24, ST officially notified customers of a price increase effective April 26, 2026, across multiple product lines. ST explained that semiconductor demand across industries is growing significantly, while material suppliers are imposing allocation fees or raising prices, energy and transportation costs are climbing, and additional expenses incurred to secure wafer fab and outsourced semiconductor assembly and test (OSAT) capacity have collectively driven up overall operating expenditures.
　　As a globally leading semiconductor supplier, ST offers the most comprehensive portfolio in the sensor market, featuring mature product lines including MEMS sensors, magnetic sensors, environmental sensors, and image sensors. Its automotive-grade sensors have passed stringent certifications like AEC-Q100 and serve as key components for global automakers such as Tesla, Volkswagen, and BMW.
　　Allegro MicroSystems: On March 22, this company—often dubbed the "hidden champion" in magnetic sensors—issued a price increase notice, announcing that all products would see price adjustments effective April 27, 2026, with a minimum hike of 10%. Allegro stated that over the past two years, the semiconductor industry has continually faced rising raw material costs, increasing labor expenses, high energy prices, logistics challenges, and constrained global manufacturing capacity. Although the company absorbed these cost pressures internally for two years, it ultimately decided to raise prices to ensure supply chain stability, invest in capacity expansion, and support long-term customer needs.

　　Allegro ships over one billion units annually to sectors including automotive engines, electric powertrains, data centers, and industrial automation, serving more than 10,000 customers worldwide. Its price increase will profoundly impact downstream manufacturers in industrial automation and automotive electronics.
　　02—Industry-Wide Price Surge
　　Sensor price hikes are merely the tip of the iceberg. Supply chain data shows that following initial price increases by wafer foundries and memory makers, there have been a cumulative 56 price adjustment notices between late 2025 and early 2026, spanning passive components, analog ICs, connectors, and upstream materials. Cost pressures on electronic components are expanding from isolated points into a broad-based escalation.
　　Specific price adjustments include:
　　Passive components: Key items such as aluminum electrolytic capacitors, tantalum capacitors, MLCCs, and resistors have seen普遍 price hikes of 10%–30%. Panasonic raised some aluminum capacitor prices by 15%–30%, KEMET increased premium tantalum capacitors by 20%–30%, and Yageo hiked prices for high-voltage, high-capacitance, and automotive-grade MLCCs by 10%–20%.
　　Analog and power management ICs: Texas Instruments implemented new pricing for core analog chips starting April 1, with increases as high as 15%–85%; Analog Devices raised overall prices by approximately 15%, with certain automotive-grade parts seeing even higher hikes.
　　Connectors and industrial control components: Omron increased prices for robotics, sensors, relays, PLCs, and temperature controllers by about 5%–35%; TE Connectivity raised its entire product line by 5%–12%, and Amphenol increased prices by 5%–15%.
　　Memory chips: Surging AI demand has led to dramatic memory price increases. Samsung’s NAND Flash prices rose over 100%, while DRAM jumped 60%–70%; SK Hynix saw DRAM increases of 60%–70%, with some LPDDR variants nearing 100% hikes.
　　Wafer foundry services: SMIC raised prices for its 8-inch BCD process by approximately 10%; Vanguard International Semiconductor adjusted overall process pricing by 10%–15%; Nexchip began uniformly increasing wafer prices by 10% for all new output starting June 1.
　　03—Root Causes: This round of component price hikes is driven by three key factors:
　　Soaring prices of precious metals. Spot gold briefly breached $5,000 per ounce, silver climbed above $93 per ounce (up over 27% year-to-date), and international copper prices exceeded $13,000 per ton. After rising 34.34% in 2025, domestic copper prices in China surged again at the start of 2026—reaching RMB 102,000 per ton in Shanghai spot markets by end-February, a year-over-year increase of over 35%. Copper and aluminum account for 60%–70% of power device packaging costs; thus, doubling raw material prices directly inflates product costs. Japanese materials giant Resonac, facing tight supply and soaring prices for copper foil and glass fiber cloth, raised prices for copper-clad laminates and bonding films by 30% effective March 1, 2026.
　　Exploding AI demand creating a "capacity suction effect." AI servers require 8–16 times more memory and computing chips than traditional servers. Global AI server shipments are projected to grow approximately 180% year-over-year in 2026, diverting massive production capacity toward AI applications and causing supply shortages in other segments.
　　Geopolitical conflicts exacerbating supply chain uncertainty. Tensions in the Middle East have driven logistics costs sharply higher, with crude oil prices remaining above $100 per barrel. According to a SEMI survey, nearly 70% of member companies identified soaring raw material prices as their primary challenge this year, while over 35% reported that extended lead times for materials and supplies pose significant issues.
　　04—Procurement Recommendations for Downstream Enterprises
　　This round of component price increases is extensive in scope, substantial in magnitude, and prolonged in duration—directly pressuring procurement costs for automation equipment manufacturers and end users. The following four strategies are recommended for procurement teams:
　　1. Secure long-term agreements early. For core automation components such as servo drives, PLCs, and sensors, negotiate long-term supply contracts with suppliers to lock in prices and capacity, mitigating risks from further price hikes.
　　2. Explore domestic alternatives. For imported components experiencing significant price increases (e.g., sensors, MCUs, power devices), evaluate performance and cost competitiveness of domestic alternatives. Leading Chinese suppliers now offer compelling value propositions.
　　3. Build moderate safety stock. For critical components with visibly extended lead times, maintain slightly higher safety inventory levels to ensure production continuity. Multiple vendors report that lead times for certain components have stretched from weeks to months.
　　4. Diversify the supply base. Avoid over-reliance on single suppliers; adopt multi-sourcing strategies to spread risk and enhance supply chain resilience.
