High-pressure units (250 bar, 400 bar) are supplied with an integrated damping
device to avoid any risk of injury in case of bursting, when the bursting pressure is
exceeded, and to comply with the regulations for UL approval�
• When the damping device is removed, it can become unusable�
• When the damping device is removed, the unit can no longer be used under

If you have any questions, please contact ifm electronic’s sales specialists�
For the scope of validity cULus:
The sensor shall be connected only by using any R/C (CYJV2) cord, having
suitable ratings�
The device shall be supplied from an isolating transformer having a secondary
listed fuse rated either
a) max 5 amps for voltages 0~20 Vrms (0~28�3 Vp) or
b) 100/Vp for voltages of 20~30 Vrms (28�3~42�4 Vp)�
