⛔ Limit Unit – Mechanical Limit Switch Sensor The Limit Unit is a compact limit switch sensor designed to provide limit protection in mechanical equipment. When the switch bar is p ressed, the output signal changes from 3.3 V to 0 V, enabling microcontrollers (MCUs) or peripheral devices to detect critical positions such as end of travel, maximum extension, or boundary limits. This reliable signal can be used to stop equipment, activate safety mechanisms, or send alerts, ensuring safe operation and preventing mechanical systems from exceeding their limits. With its simple design, long durability (up to 400K cycles), and multiple installation methods, the Limit Unit is easy to integrate into a wide range of control setups. ⚙️ Key Features ✅ Contact limit switch for precise position detection ✅ Durable design: up to 400K mechanical lifetime cycles ✅ Multiple installation methods for flexible integration ✅ Digital signal output: 3.3 V → 0 V transition ✅ Compact and lightweight for embedded systems 📦 Package Contents 1 × Limit Unit 1 × HY2.0‑4P Cable (20 cm) 🔧 Applications 🛑 Stop switch / limit switch in mechanical systems ⚙️ Boundary detection for moving equipment 🔒 Safety protection in industrial automation 🏭 Position monitoring in robotics and machinery 📊 Technical Specifications Specification Parameters Switch Bar Length 16 mm Mechanical Lifetime 400K cycles Power Supply DC 5 V Output Signal DC 3.3 V → 0 V Standby Current 2 mA @ 5 V Operating Current 3 mA @ 5 V Net Weight 6.3 g Gross Weight 11.4 g Product Size 37 × 24 × 9.5 mm Package Size 92 × 135 mm 🌍 Why Choose Limit Unit?
