Electronic pressure switch ifm electronic PK5521
The PK5521 electronic pressure switch from ifm electronic with a protection rating of IP67 has a Normally Open PNP switching output and operates in a pressure range of 0-250 bar. The easy-to-read adjustment ring allows easy and accurate switch point adjustment with a fixed hysteresis of 5 bar. Mechanical locking prohibits unauthorised manipulation. Two clearly visible LEDs indicating the switching and operating status provide the required transparency. The PK5521 electronic pressure switch 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.
