Kacon KXM-902 Light-Duty Limit Switch: Spring Wire Actuator, 1NO/1NC SPDT, IP65, 6A 250V AC
A compact Kacon light-duty mechanical limit switch with a flexible spring wire actuator, snap-action 1NO/1NC SPDT contacts, an IP65 aluminum housing, and a 6A at 250V AC resistive-load rating.
✅ For Flexible Position Detection with a Spring Wire Actuator
The KXM-902 is suited to moving targets that may approach from slightly different positions or angles. Its flexible spring wire can be deflected over a broad contact area, making it useful where a rigid plunger or short lever would require tighter alignment.
Reliable Light-Duty Detection for Machinery and Material Movement
The Kacon KXM-902 uses a spring wire actuator to detect the presence, position, or end of travel of moving machine components. A snap-action SPDT contact block provides one normally open and one normally closed circuit for control, interlock, or status-feedback functions.
The aluminum housing and plastic cover provide a compact 28 mm-wide body with IP65 protection against dust and low-pressure water jets. Gold-plated silver-alloy contacts, a 10-million-operation mechanical life, and operating rates up to 120 mechanical cycles per minute support repeatable light-duty automation service.
〰️ Flexible Spring Wire
Accepts contact across a broad area and tolerates variation in target approach or alignment.
🔄 SPDT Snap Action
One normally open and one normally closed contact support control and feedback circuits.
🛡️ IP65 Housing
Dust-tight construction resists low-pressure water jets in industrial environments.
⚙️ Long Mechanical Life
Rated for 10,000,000 mechanical operations in properly applied light-duty service.
Key Features & Benefits
- Less exact target alignment: The long flexible wire can engage moving objects that do not strike the same rigid point every cycle.
- Circuit flexibility: SPDT contacts allow the switch to open one circuit while closing another.
- Reliable low-resistance contact: Gold-plated silver-alloy contacts are designed for consistent electrical switching.
- Compact machine integration: The narrow housing fits packaging machinery, conveyors, material-handling equipment, and compact automation assemblies.
- Environmental protection: IP65 construction supports dusty equipment and areas exposed to low-pressure wash or spray.
- High cycle capability: Electrical and mechanical life ratings support repetitive position-sensing applications.

📍 Common Applications
• Packaging machinery position detection
• Conveyor and material-handling systems
• Construction equipment and light-duty automation
⚙️ Choose Spring Wire for Broad, Flexible Contact
Select the KXM-902 when the target may vary in position or needs to sweep past a flexible actuator. For a defined contact point with a rod and tip, compare the KXM-903 plastic-tip or KXM-923 metal-tip models.
🔧 Installation Notes
Mount the switch so the target deflects the spring wire without exceeding the actuator's safe travel. Wire the 1NO/1NC contacts according to the required control logic and keep the resistive load within 6A at 250V AC.
