Product Description:
NORGREN 18D Series Electro-Mechanical Pneumatic Pressure Switch
The NORGREN 18D Series (Model 0880 / 0881) electro-mechanical pneumatic pressure switch is a reliable diaphragm-actuated pressure monitor designed for industrial automation applications. It is widely used for pressure alarm systems, interlock functions, and loop control in various automated processes. This series supports vacuum pressures up to 30 bar and offers multiple port options, including G1/4, 1/4 NPT, and flange mounting configurations.
Users can choose between two electrical connection styles: DIN EN 175301-803 Form-A or M12×1 IEC 947-5-2. Additionally, the product lineup includes LABS-free variants and special brass-body versions specifically intended for water service applications. These variations make the switch suitable for handling neutral gases, liquids, and water-based media under different working conditions.
The pressure switch features a gold-plated contact microswitch that has been certified by UL and CSA, ensuring intrinsic safety and reliable operation even under challenging conditions. It is built to withstand vibrations up to 15 g and boasts a mechanical service life of up to 10 million switching cycles, delivering excellent repeatability. The standard housing material is aluminium alloy, with brass housing available for models designed for water applications. Sealing options include NBR and FPM to accommodate various environmental requirements. Its maximum ingress protection rating is IP67, making it suitable for harsh factory environments.
When the system pressure reaches the designated set-point, the single-pole double-throw (SPDT) micro-switch outputs an electrical signal. This feature enables machine interlock, alarm triggering, and on-off control for pneumatic machinery, hydraulic circuits, and water-treatment equipment.
Note: It is recommended that set-points be set within the middle of the pressure range. Avoid exceeding the rated pressure indicated on the nameplate. When dealing with inductive loads, appropriate spark-quenching protection circuits are necessary. Connectors must be purchased separately, as DIN or M12 plugs are not included.
Features:
Experience authentic NORGREN IMI quality with the comprehensive 18D‑0880 series, offering a variety of pressure ranges and port options to suit your specific application needs.
This diaphragm-operated system handles operating pressures from ‑1 to 30 bar (‑14 to 435 psi) and can withstand a maximum over-pressure of 80 bar, ensuring reliable performance under demanding conditions.
Equipped with a gold-plated contact micro-switch, the device features UL and CSA approvals and boasts an impressive mechanical lifespan of 10 7 switching cycles, guaranteeing durability and safety.
Designed for high vibration resistance up to 15 g, it supports intrinsically safe operation, making it suitable for use in challenging environments.
The product offers excellent ingress protection ratings: IP65 for DIN connectors and IP67 for M12×1 connections, providing reliable sealing against dust and water ingress.
It is compatible with neutral, non-flammable gases and liquids, and features a dedicated brass body variant specifically for water service. The system accommodates media with viscosities of up to 1000 mm 2 /s.
The switch output is SPDT with fixed hysteresis, and the device allows for unrestricted mounting positions, enhancing installation flexibility.
Seal materials are available in NBR or FPM, with LABS-free versions offered as well, covering the full vacuum range according to your application requirements.
Two electrical interfaces are supported: DIN EN175301‑803 Form‑A and M12×1 IEC947‑5‑2, providing versatile connectivity options.
