SUCO
Pressure Switch HEX 27
Reliable and precise pressure switches for hydraulic and pneumatic systems
The Suco HEX 27 mechanical and piston pressure switch is a compact and durable solution for monitoring pressure in liquids, air, and gases. It ensures stable operation, precise adjustment.
The Suco HEX 27 pressure switch is a highly reliable pressure control device equipped with a toggle microswitch and advanced configuration options. The device is characterized by high overload resistance, accuracy of operation, and a wide variety of modifications — diaphragm and piston, with silver-plated or gold-plated contacts.
Key Features
- Changeover contact: micro switch used (NO/NC in one circuit).
- Contacts: choice of silver-plated or gold-plated contacts (for low-current circuits).
- Wide pressure ranges: diaphragm and piston designs for low and high pressures.
- Hysteresis adjustment: factory setting available (except for series 0140 and 0141).
- Convenient adjustment: operating points can be adjusted on site or set during production.
- Media: liquids, gases, air, water.
- Connection options: screw and fork terminals, compatible with AMP 6.3×0.8 plugs.
- Contact protection: use protective covers or connectors to prevent dust and moisture ingress.
- High overload resistance: burst pressure up to 1000 bar for piston models.
- Compact design: 27 mm turnkey installation.
- Environmental safety: full RoHS II compliance.
