The DAIDISIKE Story — From Distribution Shop to Integrated Sensor Manufacturer
DAIDISIKE's story began when Mr. Cai founded Foshan Bozhao Optoelectronics in Beijiao, a manufacturing district at the heart of Guangdong's Pearl River Delta. In the early years the team focused entirely on sensor distribution — selling photoelectric switches, infrared detectors, and machine-guarding components to the stamping factories, packaging-line builders, and metal-fabrication shops that filled the surrounding industrial parks. That distribution period gave the company something most sensor brands lack: direct, day-after-day exposure to real factory-floor problems. Customers brought broken installations, half-working interlocks, and applications that off-the-shelf products couldn't solve. The team learned the industry by fixing it.
By 2013, accumulated engineering know-how had outgrown the distribution business model. The company restructured into Foshan DAIDISIKE Optoelectronics Technology Co., Ltd. — the DAIDISIKE (戴迪斯科) brand was registered, the first in-house R&D team was formed, and dedicated production lines were brought online. The transition wasn't a rebrand — it was the shift from selling other people's sensors to designing and building DAIDISIKE's own, with full control over optical components, electronics, firmware, housing, and quality.
Today DAIDISIKE supplies industrial sensors to manufacturers across China and to international customers including leading EV manufacturers, global 3C electronics OEMs, home-appliance makers, Tier-1 contract assemblers and MEMS/acoustic component manufacturers domestically, and connector-interconnect manufacturers (USA) and display-module producers (Korea) internationally. The product line spans safety light curtains (Type 2 and Type 4), laser distance and displacement sensors, infrared perimeter detectors, industrial safety door locks, relay and control modules, and stamping-line peripheral equipment. The thread that runs through all of it is the same as it was at the start: solve real problems for real customers on real factory floors — and back the products up with engineering support that knows the application as well as the customer does.
Sensor Manufacturing — Milestone Timeline
Foshan Bozhao Optoelectronics Founded
Mr. Cai established Foshan Bozhao Optoelectronics in Beijiao, Foshan. The team focused on sensor distribution — gaining frontline market insight by working directly with stamping factories, machine builders, and integration shops across Guangdong's manufacturing belt.
From Distribution to In-House Engineering
Customer demand pushed the company beyond distribution: customers brought specific problems that off-the-shelf sensors couldn't solve. The team built its first in-house engineering capability, designing custom safety light curtains and infrared detection systems for press lines, packaging machinery, and material-handling equipment.
Rebranded as DAIDISIKE
Formal reorganization into Foshan DAIDISIKE Optoelectronics Technology Co., Ltd. The rebrand marked the transition from a trading + custom-engineering shop into a fully integrated R&D + production + sales operation under the DAIDISIKE (戴迪斯科) brand.
Product Line Expansion
Launched the DQA, DQC, and DQB safety light curtain families — the products that became the company's recognizable identifiers in the market. Expanded into laser distance and displacement sensing (DK-G, LK-F), industrial safety door locks (DX series), and relay/control modules (A1J / B2J / D2J / E4J families).
International OEM Partnerships
First OEM contracts with international automation integrators. Worked with major Chinese OEMs across EV manufacturing, 3C consumer-electronics, home appliance, MEMS/acoustic components and Tier-1 contract assembly on factory-line safety upgrades; began serving connector-interconnect manufacturers (USA) and display-module producers (Korea) as a tier-2 component supplier.
Outdoor and Long-Range Lineup
Launched the DDSK-J 500-meter outdoor laser beam sensor family for perimeter security, and the SDLD / DLD30T series industrial LiDAR scanners for AGV/AMR safety. These products expanded DAIDISIKE's reach from indoor machine guarding into outdoor perimeter and mobile-robot safety applications.
Smart-Manufacturing Era
Released the PZ-CM10 visual intelligent learning photoelectric switch — DAIDISIKE's first AI-trainable vision sensor — and the JT14 industrial safety carpet for floor-mounted operator detection. Continuing R&D investment in Industry 4.0 / MES integration features (RS-485 Modbus, OPC-UA gateways, MQTT cloud bridges).
What We Bring to the Table
Safety photoelectric, laser/LiDAR, vision sensing, and industrial automation control — each running independent product roadmaps with shared compliance and reliability resources.
Automated SMT lines for sensor PCB assembly, in-house optical lensing and calibration, full environmental test chamber (−40 °C to +85 °C, salt fog, vibration, drop test), final acceptance against IEC 61496 / IEC 60825-1.
Lean-manufacturing discipline with full traceability from incoming inspection through final shipment. Critical-component lot-traceability for safety products; FAI / FCS on every new product launch.
Type 4 safety light curtains compliant to IEC 61496-1 / EN 61496-1; laser products Class 1 / 2 to IEC 60825-1; EMC tested to EN 61000-6-2 / EN 61000-6-4 industrial standards.
Granted invention patents covering high-stability monocrystalline silicon differential pressure sensor design, foldable light-curtain framework, stable grating-scale construction, and photovoltaic curtain-wall module integration.
Annual production capacity scales with order book; standard products ship from stock with 1-2 week lead time, custom products run 4-8 weeks depending on configuration complexity.
Customers We're Proud to Serve
DAIDISIKE products quietly run on factory floors at some of the world's largest manufacturers. Below is a representative — though deliberately partial — list of OEMs that have used DAIDISIKE sensors in their production lines:
| Customer | Region | Industry |
|---|---|---|
| Leading EV manufacturer | China | Automotive & energy storage manufacturing |
| Global 3C electronics OEM | China / global | Consumer electronics & telecom production |
| Home-appliance OEM | China / global | Home appliance manufacturing automation |
| Tier-1 electronics contract assembler | China / global | Electronics contract manufacturing lines |
| MEMS / acoustic component manufacturer | China | Acoustic & MEMS component assembly |
| Connector-interconnect manufacturer | USA | Connector and interconnect manufacturing |
| Display-module manufacturer | South Korea | Display and electronics assembly |

What Hasn't Changed Over the Years
The technology has evolved — from simple photoelectric switches to AI-trainable vision sensors and Modbus-connected MES integration — but the operating principle of the company hasn't. DAIDISIKE picks up the phone when a customer's line is down. Engineering answers application questions, not just spec questions. Manufacturing builds to the spec we ship to. And the same distribution-era discipline of knowing the factory floor still drives the company's product roadmap. That's the kind of supplier industrial automation actually needs.
