Honeywell Micro Switch PMHG135A1: Precision and Reliability in a Compact Package

The Honeywell Micro Switch PMHG135A1 is a versatile and reliable proximity sensor designed to meet the demanding requirements of various industrial automation applications. This micro switch, manufactured by Honeywell, offers a compact design, making it an excellent choice for space-constrained environments.

The PMHG135A1 is a proximity micro switch, which means it operates without physical contact between the switch and the actuator. It uses an infrared sensing technology that can detect the presence of objects within its sensing range. This feature makes it ideal for applications where there is a risk of contamination, as it eliminates the need for mechanical contact.

With a sensing range of up to 12 mm (0.47 inches), the PMHG135A1 offers high precision and accuracy. It can detect objects as small as 6 mm (0.24 inches) in diameter, making it suitable for applications where detecting small objects is crucial. The switch can be used to detect a wide range of materials, including metal, plastic, and carbon.

The PMHG135A1 is designed to withstand harsh industrial environments. It features a robust housing made of die-cast zinc and a corrosion-resistant finish, ensuring that it can withstand extreme temperatures, humidity, and vibrations. The switch is also IP67 rated, which means it is protected against dust and water immersion, making it suitable for use in wet or dirty environments.

The PMHG135A1 micro switch is easy to install and integrate into various automation systems. It comes with a normally open (NO) contact configuration, which means it is closed when an object is detected and open when no object is present. This configuration is commonly used in applications where the switch is used to activate an alarm or relay when an object is detected.

The PMHG135A1 micro switch is a reliable and cost-effective solution for various industrial automation applications. Its compact size, high precision, and rugged design make it a popular choice among engineers and automation professionals. With its wide sensing range and ability to detect various materials, it offers flexibility and versatility in a compact package.
