The part number **14CEC-2102-R/W** generally refers to a specific type of **Magnetic Proximity Sensor** or a **Magnetic Contact/Switch**, often used in security systems, industrial automation, or position sensing. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. Component Overview These components are typically **Reed Switches** housed in a protective casing. They operate based on the presence of a magnetic field. When a magnet comes within a specific range, the internal reeds either close (completing the circuit) or open. ### 2. Technical Specifications While specific manufacturers may vary slightly, the standard specifications for this series are as follows: | Parameter | Specification (Typical) | | :--- | :--- | | **Contact Type** | Form A (Normally Open - N.O.) | | **Switching Voltage** | Max 100V DC/AC | | **Switching Current** | Max 0.5A | | **Power Rating** | 10W / 10VA | | **Operating Distance** | 15mm to 25mm (Gap) | | **Color Code** | R = Red / W = White (Housing Color) | | **Housing Material** | ABS Plastic / Flame Retardant | --- ### 3. Key Electronic Features * **Non-Contact Operation:** Since it relies on magnetism, there is no physical friction between the sensor and the actuator, leading to a long mechanical life. * **Hermetically Sealed:** The internal reed switch is usually sealed in glass with an inert gas, protecting the contacts from oxidation, dust, and moisture. * **Passive Component:** It does not require a power supply to operate; it functions purely as a physical switch triggered by an external magnetic field. * **Low Resistance:** When closed, the contact resistance is typically very low (<200mΩ), ensuring minimal signal loss. ### 4. Wiring and Implementation The device is usually provided with two wires (leads). In a standard security or control loop, it is wired as follows: ```cpp // Example: Logic for a Microcontroller (e.g., Arduino) int sensorPin = 2; // Connected to one lead of 14CEC-2102 int val = 0; void setup() { pinMode(sensorPin, INPUT_PULLUP); // Use internal pull-up resistor } void loop() { val = digitalRead(sensorPin); if (val == LOW) { // Magnet is present (Door Closed) } else { // Magnet is absent (Door Open) } } ``` --- ### 5. Common Applications 1. **Security Systems:** Monitoring doors and windows. 2. **Industrial Positioning:** Detecting the end-of-travel for pneumatic cylinders or robotic arms. 3. **Appliances:** Sensing if a lid or cover is properly closed before operation.
