Herga Vacuum Pressure Sensor 250V 21A Nylon 12 Housing Neoprene Diaphragm Stainless Steel Spring 6721-0021

The Herga 6721-0021 Pressure Sensor is engineered for vacuum pressure detection within a range of 185 mbar minimum operating pressure and maximum operating pressure of 686 mbar. This sensor operates at a voltage of 250V and supports a contact current of 21A with a 1 CO contact configuration, making it suitable for a wide variety of industrial applications where precise vacuum sensing is critical.

Constructed with a robust Nylon 12 housing, the sensor offers enhanced durability and resistance to environmental factors. It features a neoprene diaphragm that provides sensitive and responsive pressure detection, while the stainless steel spring ensures reliable mechanical operation under fluctuating pressure conditions.

The unit is fully adjustable, allowing for fine-tuning to meet specific application needs. It includes five fixing holes arranged on a 28.5mm pitch circle diameter, designed to fit No. 4 self-tap screws for secure mounting. The sensor can reliably function within the temperature range of -5°C to 70°C, enabling usage in diverse climatic and industrial environments.

This vacuum pressure sensor is calibrated for a vacuum rating spanning from -75 to -270 inches water gauge (in. WG), making it ideal for pneumatic and fluid power controls, vacuum systems, and other industrial equipment monitoring. Compliant with RoHS standards, it meets environmental safety requirements without hazardous area certifications.
