The SICK AL20E-NM111 is a versatile, short-range, non-contact inductive proximity sensor. It is designed for the reliable detection of metallic objects (primarily ferrous metals like steel and iron) in a wide array of industrial automation applications. Its robust design and dependable performance make it a fundamental component for position sensing, end-of-travel checking, and counting tasks.
Key Features
Non-Contact Detection: Provides wear-free operation compared to mechanical switches, leading to higher longevity and reliability.
Embedded Mounting Capability: Can be mounted flush (level) in a metal bracket without any reduction in its specified sensing range, simplifying mechanical design and installation.
Short-Circuit and Reverse Polarity Protection: Built-in electronic protection safeguards the sensor from accidental wiring errors and electrical faults, preventing damage and minimizing downtime.
LED Status Indicator: An integrated red LED provides clear visual confirmation of the switching state (target detection) and power status, aiding immensely in setup, commissioning, and troubleshooting.
Rugged Housing: Features a robust nickel-plated brass housing and a PTFE (Teflon) sensing face, offering good resistance to many industrial chemicals, oils, and coolants.
Extended Temperature Range: Suitable for operation in a wide range of ambient temperatures.
