The **1M5AN-R** is a specific part number typically associated with **M8 sized Industrial Proximity Sensors**, most commonly produced by manufacturers like **Panasonic (formerly SUNX)** or within specialized electronic component series. Below is a detailed breakdown of the electronic specifications, functionality, and applications for this component. --- ### 1. General Specifications The "1M5AN-R" generally refers to a **Cylindrical Inductive Proximity Sensor**. These sensors are used to detect the presence of metallic objects without physical contact. | Feature | Specification (Typical) | | :--- | :--- | | **Sensing Distance** | 1.5 mm | | **Thread Size** | M8 × 1 | | **Output Type** | NPN / Normally Open (NO) | | **Mounting** | Shielded (Flush mountable) | | **Voltage Range** | 12V to 24V DC | | **Response Frequency** | ~1 kHz to 2 kHz | | **Material** | Stainless Steel or Nickel-plated Brass | --- ### 2. Part Number Deciphering While codes vary slightly by brand, the alphanumeric string usually follows this logic: * **1M:** Often indicates the sensing range (e.g., 1.5mm). * **5:** Can denote the voltage rating or housing length. * **A:** Usually represents the output logic (e.g., NPN). * **N:** Stands for "Normally Open." * **R:** Often indicates a **flexible cable** or "Robot Cable" (high-flex life), making it suitable for moving parts like robotic arms. --- ### 3. Connection Diagram Inductive sensors like the 1M5AN-R typically use a standard 3-wire DC color code: ```markdown Brown (BN) ---- [+] Positive (12-24V DC) Blue (BU) ---- [-] Negative (0V) Black (BK) ---- [Output] Signal to PLC/Relay ``` --- ### 4. Key Applications Because of the **-R (Robot Cable)** designation and the small **M8 size**, this part is commonly found in: 1. **Robotic End-Effectors:** Detecting if a metallic tool or workpiece is successfully gripped. 2. **High-Speed Assembly Lines:** Counting small metal parts (screws, nuts, gears). 3. **Position Sensing:** Detecting the home position of a sliding axis in CNC machinery. 4. **Limited Space Environments:** The compact M8 diameter allows installation in tight mechanical housings. --- ### 5. Selection Considerations If you are looking for a replacement, verify these three critical factors: * **NPN vs. PNP:** Using the wrong polarity will prevent the PLC from reading the signal. * **Shielded vs. Unshielded:** Shielded sensors (like this one) can be buried flush in metal, whereas unshielded ones require a metal-free zone around the head. * **Cable Flex:** The "-R" implies high durability for bending; a standard cable might fail prematurely in a motion-heavy application. ---
