Industrial Safety Light Curtains, LiDAR & Sensors — Factory Direct from DAIDISIKE
Foshan DAIDISIKE Optoelectronics manufactures machine-safety and industrial sensing products: Type-4 architecture safety light curtains, 2D TOF LiDAR scanners, guard-locking door switches, proximity and photoelectric sensors. OEM/ODM supported, engineering support included.
Who We Are — Inside the DAIDISIKE Sensor Factory
A three-minute look at who actually builds these sensors: the production floor in Beijiao, Shunde, the assembly and test benches, and the engineers who run the on-site machine-safety assessments behind our application guides.

We manufacture at Beijiao, Shunde, in Foshan — the middle of China's Pearl River Delta machine-building belt. This short film walks the production floor, the assembly and test benches, and introduces the engineers who carry out the on-site machine-safety assessments that our application guides are written from.
If you are sourcing from China and want to know whether you are talking to a factory or a trading company, three minutes here will answer it faster than a spec sheet.

Featured Series
DQC General Safety Light Curtain
General-purpose through-beam safety light curtain for presses, hydraulic and shearing machines and automatic doors — a transmitter/receiver pair in 8 beam pitches from 10 to 200 mm, standard sensing distance 0.3-3 m or 0.3-6 m, with NPN or PNP output. Designed to the Type 4 architecture of IEC 61496 and Category 4 of ISO 13849-1.
DLD-50D 2D TOF LiDAR for Navigation & Mapping (50 m)
50 m-range 2D TOF LiDAR for mobile robot navigation and mapping — ±20 mm repeatability, 280° FoV, Ethernet output.
DX-D6 Guard Locking Safety-Door Switch
Guard locking safety-door switch: 2000 N holding force, redundant dual outputs, RFID-coded actuators.
DKE-L3 Press Brake Laser Protection
Ram-mounted laser guarding that tracks the punch tip on press brakes and shears without blocking hand-fed work.
DQSA Area Protection Light Curtain
One emitter/receiver pair and passive mirrors fold the beam around 2-4 sides of a danger zone -- built to a Category 4 / Type 4 design basis (IEC 61496-1/2, EN 61496-3:2019, EN ISO 13849-1:2015 Cat 4 PLd); certification documents available on request.

Installing a Safety Light Curtain on a Punch Press — Mounting, Alignment & Test
Watch a safety light curtain being fitted to a mechanical power press: bracket mounting on the press frame, emitter-to-receiver alignment, and the final interrupt test before production restarts. A practical reference if you are retrofitting punch press guarding to pass a safety inspection.

Robot Cell Perimeter Guarding with Infrared Safety Light Curtains
Infrared light curtains fencing the working envelope of an industrial robot: entry through the curtain drops the safety circuit before a person can reach the arm. An alternative to full hard guarding when parts flow in and out of the cell.

3D Animation: How Light Curtains, Door Locks, Safety Mats & LiDAR Guard a Machine
A three-minute animated tour of a guarded machine: safety light curtains at the opening, guard-locking switches on the doors, pressure-sensitive mats on the floor and a laser scanner watching the approach zone — and how each one feeds the stop circuit.

Pneumatic Automatic Feeder on a Pressing Machine — A50 / A100 / BX150 Running
An air feeder with pneumatic clamping advancing strip stock into the die at a fixed pitch, cycle after cycle. Automatic feeding keeps hands out of the point of operation — the feed area itself is then guarded with a safety light curtain.

Why buy from DAIDISIKE?
Real manufacturer, not a trader
Our factory in Shunde, Foshan designs and builds the sensors we sell — you get engineering answers, not reseller guesses.
Deep model coverage
Thousands of orderable part numbers across 140+ series: beam pitches, sensing ranges, NPN/PNP outputs, connector options.
OEM / ODM friendly
Custom protective heights, cable lengths, housings and private labeling for machine builders and brand owners.
Straight answers on compliance
Certification documents available on request — we tell you exactly what each product line carries before you order.
Both NPN and PNP, on almost every series
Most DAIDISIKE sensors ship in both NPN (sinking) and PNP (sourcing) versions, with NO/NC selectable — so the same part number family works with Japanese, Chinese and European PLCs without a converter.
Model codes you can read
Our light-curtain part numbers encode the specification directly: DQC06/10-50 means 6 beams, 10 mm pitch, 50 mm protective height (height = (beams − 1) × pitch). Quote and reorder without a catalog.
