Core Features
Precision Plunger Actuator for Linear Detection: Functions as a compact micro limit switch with a spring-loaded plunger, engineered for accurate linear position sensing in neutral industrial environments. The 8mm stainless steel plunger (3mm stroke) provides direct, perpendicular contact with targets, ensuring reliable actuation in applications requiring precise linear motion detection (e.g., sliding components, part alignment, or door latches in electronics and light machinery).
Snap-Action Mechanism for Fast Response: Equipped with a high-speed snap-action contact system that switches in ≤3ms, minimizing contact bounce and preventing false signals in sensitive control circuits. This makes it ideal for high-cycle applications (e.g., pick-and-place robots, automated assembly lines) where rapid, consistent feedback is critical. The switch features a single-pole double-throw (SPDT) configuration (1 NO + 1 NC) for versatile integration.
Low-Voltage Compatibility for Micro Systems: Rated for DC 30V (maximum) with a switching current of 1A (resistive), optimized for low-power control systems such as:
PLC input modules in precision automation (e.g., Siemens S7-1200, Mitsubishi FX5UC).
Sensor networks in medical devices and laboratory equipment.
Battery-powered portable machinery where energy efficiency is essential.
Durable, Space-Saving Housing: Housed in a glass-reinforced thermoplastic housing (UL94 V-0) with a diminutive footprint (29mm × 19mm × 13mm) and lightweight design (13g), suitable for space-constrained installations (e.g., inside small enclosures, on miniature robotic arms, or within electronics testing fixtures).
Consistent Actuation Force: The plunger’s fixed return force (1.0N) ensures reliable contact with targets without causing damage to delicate components (e.g., plastic parts, circuit boards). Its rounded tip reduces wear on both the switch and contact surfaces, extending service life in high-cycle applications.
Dust-Resistant Protection: Meets IP40 protection (IEC 60529) to shield internal components from dust and particulate matter, ensuring reliability in cleanrooms, electronics manufacturing facilities, and controlled laboratory environments.
Simplified Installation: Designed for surface mounting via two M2 screws, with solder terminals for secure connection to fine-gauge wires (24–30 AWG). Its low profile minimizes interference with adjacent components, while the plunger’s axial alignment simplifies integration into linear motion paths.
