Suco - 0122/0123 Pressure Switch
IP67
The SUCO 0122/0123 series features compact, rugged diaphragm-style mechanical pressure switches with an integrated M12×1 connector and zinc‑plated steel HEX‑24 housing, conforming to DIN EN 61076‑2‑101‑A standards and IP67/IP6K9K ingress protection. They operate up to 42 V AC/DC with a resistive contact rating of 4 A, offering SPST normally open or closed contacts. The switches allow six field-adjustable pressure ranges with overpressure resistance up to 300 bar (diaphragm type) and higher ranges up to 600 bar. Technical specifications include excellent repeatability, fast switching frequency (up to 200 cycles/min), and a long mechanical life expectancy of 1 million cycles. Warranty against harsh conditions includes vibration tolerance (10 g, 5–200 Hz), shock resistance (294 m/s²), and superior seal compatibility—NBR, EPDM, FKM, FFKM, HNBR, and silicones—covering broad media types and temperature tolerances from –40 °C up to +120 °C depending on seal material.
These switches serve as reliable pressure monitors and safety devices in mobile hydraulic systems, industrial machinery, water and braking systems, and pneumatic setups. Their compact HEX‑24 design with integrated M12 connector enables quick installation and secure electrical connections even in tight engine bays or control panels. On-site adjustability and factory pre-setting options allow technicians to calibrate switch points precisely for pump start/stop control, system protection, leak detection, or interlock management. With robust overpressure tolerance, IP67 dust/water resistance, and compatibility with hydraulic oils, fuels, and aggressive media, the 0122/0123 ensures reliable long-term operation in harsh, heavy-duty environments like construction, agriculture, and off-highway equipment.
