9981-1100

Proximity Sensors are vital components for many industrial automation field, where accurate sensing of the environment is essential for efficient operations. The 9901-1100 proximity sensors are no different, with its accuracy and robust construction making them a dependable choice for sensing applications.

What is the 9901-1100 Proximity Sensor?

The 9901-1100 is a tubular shaped, non-encoding type, DC two-wire switch sensor with a flush mounting. Its housing is made of stainless steel and is IP67 rated for protection against dust and water. It has a sensing range of 1-2 cm and a voltage range of 50 to 250VAC/DC. It is capable of detecting objects at a distance, usually up to 10 cm, without making contact with them. It is very common in factory automation, door entry systems, or security applications. Its sensing element consists of an oscillator coil and a permanent magnet, which vibrate at a frequency of 5kHz. This vibration allows the sensor to detect the presence of any metallic objects within its proximity.

9901-1100 Application Field and Working Principle

The 9901-1100 is used in many industrial automation and entry systems where accurate sensing is required. Its robust design and accurate sensing make it a reliable choice for a wide range of applications. It is commonly used in door entry systems and in security applications. Its high reliability and long-term stability make it suitable for long-term service in harsh environments and for industrial automation applications. The 9901-1100 is also used in automation machines where it can detect the presence of a foreign object or a defective product.

The 9901-1100 works with a simple working principle. The sensor consists of two coils which are vibrating at 5kHz, one of them is oscillating and the other one is permanent. When a metallic object or any other conductive element approaches the 9901-1100, an alternating electric field is generated in the two coils which causes a resonance effect and a voltage increase in the circuit. This voltage increase alerts the controller of the 9901-1100 that an object is present and in the proximity of the sensor. The controller will then send a signal to the automation system to indicate if an object is present or not.

Advantages of Using 9901-1100 Proximity Sensors

The 9901-1100 proximity sensors offer several advantages over traditional inductive and capacitive sensors. For one, they have a wide range of voltages they can operate on, from 50 to 250VAC/DC. This ensures that they can be used in a variety of applications as well as in various conditions. They also offer accurate sensing of objects in their proximity, up to 10 cm, without contact, making them ideal for automation, security, and door entry systems. Furthermore, their robust construction and IP67 rating make them suitable for harsh industrial environments. All of these features make the 9901-1100 an excellent choice for many industrial applications.

Conclusion

The 9901-1100 proximity sensors are a reliable and dependable choice for sensing applications in different industrial settings. With its robust construction, accurate sensing range, and full voltage range, it is suitable for a wide range of indoor and outdoor applications. The 9901-1100 works by using two coils vibrating at 5kHz which generate an alternating electric field when a metallic or conductive object approaches the sensor. This in turn increases the voltage in the circuit and allows the controller to alert the system that an object is present. The 9901-1100 is a great choice for all your industrial applications and automation needs, providing reliable and accurate sensing.
