Product Information
HM/HO350 Hydraulic Pressure Switches
The HM/HO350 Hydraulic Pressure Switches are compact and lightweight devices used in various applications such as high/low pressure alarms in CNC machines, compressors, hydraulic power packs, and manifolds/stacks with sandwich plates. They offer three mounting styles and come with a lockable protective cap to prevent tampering (optional). The switches have a choice of wetted parts to suit different working media. The electrical rating is 5A, 250VAC; 0.2A, 250 VDC (res.).

Product Usage Instructions
To order the HM350 Hydraulic pressure switches, follow the below steps:
Group 1: Model
Specify “HM” for Hydraulic Pressure Switch or “HO” for Hydraulic Pressure Switch.
Group 2: Range Code
Select “350” as the range code for the HM350 Hydraulic pressure switch.
Group 3: Base Type
Select one of the following base types:
- “S” for Subplate mounting.
- “L” for Line Mounting.
- “V” for Vertical Stacking (2 mounting holes).
- “R” for Vertical Stacking (4 mounting holes).
Group 4: Protective Cap
Select one of the following options:
- “U” for without any protective cap.
- “P” for with a lockable protective cap.
Group 5: Wetted Parts
Select “M” for Standard Wetted parts.
Group 6: Enclosure
Select “0” for IP 65 enclosure.
For example, to specify a hydraulic pressure switch with a pressure range from 35 bar to 350 bar, as a subplate mounting element without a lockable protective cap and standard wetted parts with a standard enclosure, the full model number would be:
Group 1: HM
Group 2: 350
Group 3: S
Group 4: U
Group 5: M
Group 6: 0
Please specify the full model number when ordering to avoid ambiguity. If only the first two groups are specified, uncalibrated switches with standard wetted parts and enclosures will be supplied.
