QPSH-AP-42

Introducing the QPSH-AP-42 Pressure Switch, a versatile and reliable solution for your automation needs. This pressure switch is designed to operate within a wide pressure range of 14.5 to 145 psi (1 to 10 bar), making it an ideal choice for various industrial applications. The switch is powered by a 12-24V DC power source, ensuring compatibility with a broad range of power supplies.

The QPSH-AP-42 is meticulously crafted with high-quality components to ensure durability and precision. The switch body is made of robust materials, providing resistance to harsh environments and ensuring a long service life. The diaphragm, which is in direct contact with the process media, is made of a strong and flexible material, allowing it to accurately detect pressure changes.

The QPSH-AP-42 features a normally open (NO) contact configuration. When the pressure in the system reaches the set point, the diaphragm deflects, closing the contact and completing the circuit. This allows the connected device to respond to the pressure change. The switch is designed to provide a quick and reliable response to pressure fluctuations, ensuring timely and accurate automation.

The QPSH-AP-42 is easy to install and use. It comes with clear markings on the pressure scale, making it simple to set the desired pressure level. The switch also includes a test point, allowing you to easily check the status of the switch without disrupting the system.

The QPSH-AP-42 pressure switch is designed to provide reliable and accurate pressure detection in a variety of industrial applications. With its wide pressure range, 12-24V DC power compatibility, and robust construction, this switch is an essential tool for any automation system. Trust the QPSH-AP-42 to help you maintain optimal system performance and ensure the safety and efficiency of your operations.
