Festo
7451
PE converter PE-VK-5.1
The Festo part number 7451 is a pneumatic-to-electric pressure transducer measuring relative pressure in compressed air systems operating from 0 to 0.025 MPa, where oil lubrication is not possible within an ambient temperature range of -10 °C to 50 °C. Featuring a contact-based changeover switch with a fixed hysteresis threshold value, this unit provides a switch-on point of 0.0005 bar and a switch-off point of 0.0001 bar, supporting a maximum switching output voltage of 250 V AC or DC across AC-12, AC-14, DC-12, and DC-13 utilization categories via a 4-core cable connection. This component conforms to EN 60947-5-1 standards and carries CCC certification, CE marking under the EU low voltage directive, and UKCA marking for electrical equipment.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
