Why Langir is Your Go-to Choice
Responsive Touch in Harsh Conditions
19mm capacitive switches detect capacitance shifts with 0N force, auto-calibrating for gloves/humidity. 50M cycles ensure reliability without mechanics. 316L stainless or aluminum housings machined to precise tolerances, anodized for durability. IP68/IP69K per IEC 60529 seals against water jets; production includes sensor calibration and ESD testing.
Vandal-Proof for Public Interfaces
IK10 rating defies impacts, ideal for kiosks. Seamless surface resists chemicals/dirt for easy cleaning. NPN/PNP outputs (200mA/24VDC) with momentary/latching modes suit controls. Assembly: CNC housing, PCB mounting, wire termination (300mm leads), and burn-in for stability. -20°C to +65°C operation.
Flexible LED and Power Efficiency
LED options (1/2 colors) sync with output—e.g., green ON closed. Low 7–25mA draw fits low-power systems. Sensitivity tweak via ground wire enhances glove use. Workflow: material selection (316L stainless), integration, and QA for consistent thresholds. RoHS-compliant for global OEMs.
Seamless OEM Panel Integration
19mm bushing fits standard cutouts; HE14 connectors speed wiring. No moving parts boost hygiene. Manufacturing emphasizes precision anodizing, sealing verification, and cycle simulation. ESD tolerance (±15kV air) protects in EMI-heavy sites like automation.
Precision Path to OEM-Grade 19mm Switches
Langir’s process delivers customized capacitive switches with zero compromises on reliability or fit.
1. Spec definition and feasibility
Gather needs: output (NPN/PNP), materials (316L), LED, sensitivity. Confirm 19mm fit and environment (IP69K). Early review prevents rework, aligning with OEM deadlines.
2. Prototype fabrication and validation
Machine housings, embed sensors/LEDs, wire (300mm). Test 0N response, auto-calibration, IK10 impact. Client checks sealing/ESD before approval.
3. Tooling and small-batch pilots
Finalize for anodizing/assembly. Pilots endure temp cycles (-20°C/+65°C), 50M sims. Refine glove sensitivity for your use case.
4. Scale production and rigorous QA
Lines produce consistently; inspect IP68, output (200mA), LEDs. Batches certified RoHS-ready for shipment.
5. Global delivery and follow-up
Pack securely; support reorders with spec matching. Ensures ongoing supply chain stability.
