High-pressure piston pressure switches from SUCO (including 0164, 0184, 0185, and 0142 series) are engineered for operating pressures up to 400 bar across high-tonnage stamping presses, plastic injection molding machinery, and heavy off-highway mobile equipment.

For hazardous chemical and petrochemical installations, ATEX and IECEx certified explosion-proof series 0165, 0340, and 0341 provide flameproof Ex d and intrinsically safe Ex ia protection in Zone 1, 2, 21, and 22 explosive gas and combustible dust atmospheres.

• Operating pressure rating up to 400 bar: precision hardened steel piston with specialized PTFE low-friction seals
• ATEX and IECEx explosion-proof certification: certified Ex d and Ex ia compliance for petrochemical plants
• High mechanical cycling endurance: tested beyond 1 million switching cycles under severe hydraulic pulsation
• Corrosion-resistant stainless steel 1.4404 (AISI 316L) housings: optimal for offshore and caustic processing media

SUCO 0500, 0510, and 0570 Series Electronic Pressure Switches and VDMA Display Units

Intelligent electronic pressure switches from SUCO combine the functionality of a pressure switch, digital pressure gauge, and continuous transmitter within a rugged modular casing.

Series 0500, 0501, 0510, and 0570 integrate ceramic thick-film or piezoresistive sensing cells, microprocessor-controlled hysteresis and switching delay damping, a 330-degree rotatable high-brightness LED display, and standardized menu navigation conforming to VDMA 24574-1 for machine tools and

robotic assembly cells.

• Dual independent PNP/NPN transistor switching outputs or combination with 4-20 mA / 0-10 V analog signal
• Standardized VDMA 24574-1 menu structure: rapid two-button setpoint and window mode configuration on-site
• 330-degree rotatable display and electrical head: effortless reading in constrained machine installation bays
• High measuring accuracy of 0.5% F.S.: continuous microprocessor temperature compensation from -20 to +85 deg C

SUCO 0601, 0630, and 0645 Series Pressure Transmitters and CANopen Smart Sensors

Precision pressure transmitters and transducers from SUCO across 0601, 0602, 0630, 0645, 0675, 0680, and 0690 series convert static and dynamic media pressure into proportional, noise-immune electrical signals.

Utilizing cutting-edge Silicon-on-Sapphire (SOS) and ceramic diaphragm sensing elements, these transmitters exhibit exceptional zero-point stability, high overload burst margin, and immunity to cavitation.

Advanced digital bus models support native CANopen and SAE J1939 communication for smart mobile machinery.

• Silicon-on-Sapphire (SOS) sensor technology: zero mechanical hysteresis with annual drift below 0.2% F.S.
• Industry-standard analog outputs: 4-20 mA current loop, 0-10 V voltage, and 0.5-4.5 V ratiometric signals
• Digital CANopen and SAE J1939 protocols: direct streaming of pressure, temperature, and diagnostic metrics
• Pressure spans from 0-0.5 bar up to 0-1,000 bar: compatible with hydraulic oils, fuels, coolants, and hydrogen

SUCO 0150 and 0151 Series Mechanical Vacuum and Differential Pressure Switches

Mechanical vacuum switches from SUCO (0150 and 0151 series) deliver accurate, fail-safe monitoring of technical negative pressure across a tuning span of -0.1 to -0.85 bar (-100 to -850 mbar).

These compact devices are deployed in industrial automated packaging machines, vacuum thermoforming stations, robotic suction handling grippers, and suction filtration lines to detect vacuum leaks or premature filter element clogging before process failure occurs.

• Negative pressure setpoint range from -100 to -850 mbar: fine-pitch screw sensitivity calibration on the line
• High overpressure proof pressure up to 20 bar: prevents diaphragm rupture during high-pressure reverse purges
• Elastomer diaphragm options in NBR, EPDM, and FKM: broad chemical resistance to dry air, oil vapor, and gases
• High electrical contact rating up to 250 V / 2 A: directly commands solenoid valves and PLC digital input cards

SUCO F, S, and C Series Smooth-Start Centrifugal Friction Clutches

Centrifugal friction clutches from SUCO in F-type (straight guide blocks), S-type (pivoted centrifugal weights), and C-type configurations provide automated, shock-free mechanical load engagement when the prime mover accelerates to operating speed.

These clutches allow electric motors and internal combustion engines to start completely unloaded at idle, eliminating high startup current surges, preventing drive belt slippage, and shielding powertrains from destructive torsional spikes on plate compactors, compressors, and pumps.

• Smooth unloaded acceleration: automatic mechanical engagement triggered purely by centrifugal force at set RPM
• Torque transmission capacity from fractional kW to 100+ kW: available with integrated pulleys, flanges, or hubs
• High-wear asbestos-free friction linings: stable dynamic friction coefficient and optimal thermal dissipation
• Powertrain anti-stall protection: clutch automatically disengages the driven load if engine RPM drops abruptly

SUCO Passive Centrifugal Speed-Limiting Safety Brakes for Lifting Systems

Autonomous centrifugal safety brakes from SUCO represent maintenance-free, passive mechanical protection systems designed to automatically govern descent speed or rotational velocity without requiring external electric power.

These brakes are engineered into cable winch hoist drums, passenger and materials construction elevators, suspended facade cradles, emergency rescue descent equipment, and wind turbine yaw/pitch drives to ensure controlled descent during emergency power outages.

• Fully autonomous zero-power operation: mechanical braking governed solely by centrifugal force without sensors
• Self-regulating smooth braking torque: descent velocity is locked strictly within preset maximum safety limits
• High thermal dissipation friction linings: safely absorbs large kinetic energy without glazing during descent
• Compliance with EN 1808 European hoist safety regulations and international machinery safety directives
