Core Features Diamond-Tip Toggle Lever for Precision Sensing: Functions as a micro limit switch with a compact toggle lever featuring a 3mm diamond-shaped POM (polyoxymethylene) tip, engineered to detect small, delicate, or irregularly shaped targets in tight spaces. The tip’s narrow profile ensures reliable contact with minimal surface area, making it ideal for sensing electronic components, thin films, or fragile workpieces without causing damage. Snap-Action Mechanism for Fast Response: Equipped with a high-speed snap-action contact system that achieves switching in ≤4ms, minimizing contact bounce and preventing false signals in high-precision control systems. This design supports 1 million+ mechanical operations, ensuring longevity in high-cycle applications such as automated inspection systems or micro-assembly lines. The switch features a single-pole double-throw (SPDT) configuration (1 NO + 1 NC) for flexible integration. Low-Voltage Compatibility for Micro Systems: Rated for DC 30V (maximum) with a switching current of 1A (resistive), optimized for low-power electronics and precision automation. It is ideal for: PLC input circuits in micro-manufacturing (e.g., Siemens S7-1200, Allen-Bradley Micro820). Sensor networks in laboratory automation equipment. Battery-powered devices where energy efficiency is critical. Ultra-Compact Housing: Housed in a glass-reinforced nylon housing (UL94 V-0) with an ultra-small footprint (28mm × 15mm × 12mm) and lightweight design (10g), suitable for installation in space-constrained environments (e.g., inside small enclosures, on robotic end-effectors, or within electronics testing jigs). Adjustable Actuation Parameters: The toggle lever offers 180° rotation for versatile alignment with targets, while its 12mm length balances sensitivity and reach. A light return force (0.8N) ensures gentle contact with fragile workpieces, preventing deformation or damage during actuation. Dust-Resistant Protection: Meets IP40 protection (IEC 60529) for dust resistance, making it suitable for indoor, controlled environments such as cleanrooms, electronics manufacturing facilities, or medical device assembly lines. Simplified Installation: Designed for surface mounting via two M2 screws, with solder terminals for secure connection to fine-gauge wires (24–30 AWG). The lever’s tool-free adjustment allows on-site calibration without dismounting the switch. Typical Applications The ALCO Switch MST115D is engineered for precision sensing of small components in micro-manufacturing, with core use cases including: Electronics Assembly: Installed in chip placement machines to detect the presence of ICs, resistors, or capacitors on PCBs, where the diamond tip ensures reliable contact with tiny surfaces. Medical Device Manufacturing: Integrated into catheter or syringe assembly lines to verify component alignment, with the light actuation force preventing damage to delicate medical-grade materials. Optical Equipment Testing: Used in lens or camera module testing stations to sense part positioning, ensuring precise alignment for calibration and quality control. Watch & Jewelry Manufacturing: Deployed in micro-machining setups to detect the position of small metal components (e.g., watch gears, jewelry clasps), ensuring accurate processing and assembly. Laboratory Automation: Integrated into liquid handling robots or sample preparation systems to sense the presence of microtubes or well plates, providing feedback for precise robotic movements.
