Product description
Electronic pressure switch ifm efector PK6521
The PK6521 electronic pressure switch from ifm electronic, with a protection rating of IP67, has a complimentary switching output and operates in a pressure range of 0-3625 psi (0-250 bar). The two easy-to-read adjustment rings allow easy and accurate switching and reset point adjustment in both liquid and gas media. Mechanical locking prohibits unauthorized manipulation. Two clearly visible LEDs indicating the switching and operating status provide the required transparency. The PK6521 electronic pressure sensor, with G 1/4 male process connection and M12 connector, is particularly suited for use in hydraulic and pneumatic applications as well as for pressure monitoring and cooling technology.
