Its coded actuator principle helps provide dependable detection while reducing the possibility of unintended switching. With a compact rectangular housing, 5 mm sensing range, 24 V DC operation and IP67 protection, it is suitable for machine guarding, access monitoring and safety door applications where dependable position detection is required.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MN204S is a magnetically coded safety sensor developed for reliable monitoring of movable guards, doors and protective equipment. It uses a defined coded actuator to provide dependable switching when the protected element reaches the required position. The compact rectangular construction supports installation in space-limited machine areas. Its potential-free normally open outputs and 24 V DC supply make it suitable for integration with safety-related control systems. The sensor is intended for continuous industrial operation.
The MN204S provides a 5 mm sensing range with its defined actuator and uses two normally open potential-free outputs. Its compact 36 x 13 x 26 mm housing allows convenient mounting around machine guards and access doors. The sensor supports a switching frequency of up to 150 Hz and has a response time of 10 ms to a safety request. IP67 protection supports use in demanding industrial environments.
The sensor is designed for dependable safety-position monitoring where repeatable detection is important. It operates across an ambient temperature range of -25 to 80 °C and can provide extended operational life under defined conditions. Shock resistance up to 30 g and vibration resistance up to 10 g support industrial machine environments. The sensor can be used with suitable IFM evaluation units for higher safety performance levels.
