Product Description:
NORGREN 18D Series Electro-Mechanical Pneumatic Pressure Switch
The NORGREN 18D Series, comprising Model 0880 and 0881, is a reliable diaphragm-actuated pressure switch designed for industrial automation applications. It serves as an effective pressure monitor for alarms, interlock mechanisms, and loop control systems. This series accommodates a wide range of pressures, from vacuum levels up to 30 bar, and provides multiple port configuration options including G1/4, 1/4 NPT, and flange mounting.
Users can select between two types of electrical connections: the DIN EN 175301-803 Form-A and the M12×1 IEC 947-5-2. Additionally, LABS-free variants and special brass-body versions tailored for water service are available, making the switch suitable for neutral gases, liquids, and water-based media.
Featuring a gold-plated contact microswitch certified by UL and CSA, the device offers intrinsically safe operation and withstands vibrations up to 15 g. Its mechanical service life can reach up to 10 million switching cycles, ensuring excellent repeatability. The standard housing is made of aluminium alloy, whereas models intended for water applications utilize a brass housing. Seal materials include NBR and FPM, and the maximum ingress protection rating is IP67, allowing the switch to perform reliably in harsh factory environments.
When the system pressure attains the pre-set threshold, the SPDT micro-switch triggers an electrical signal that can be used for machine interlocks, alarms, and on/off control functions in pneumatic machines, hydraulic circuits, and water treatment equipment.
Note: It is recommended to set the pressure set-points near the center of the operating range. Avoid exceeding the rated pressure indicated on the nameplate. For inductive loads, spark-quenching protection circuits are necessary. Connectors must be purchased separately, as DIN or M12 plugs are not included.
Features:
Experience the genuine quality of NORGREN IMI with the comprehensive 18D‑0880 series, offering a wide selection of pressure ranges and port options to suit various applications.
This diaphragm-operated device functions efficiently within an operating pressure range of ‑1 to 30 bar (‑14 to 435 psi), and can withstand a maximum over-pressure of up to 80 bar, ensuring reliable performance under demanding conditions.
Equipped with a gold-plated contact micro-switch, it meets UL and CSA approvals and boasts an impressive mechanical lifespan of 10 million switching cycles, providing durability and consistent operation.
Designed to endure high vibration environments up to 15 g, this product supports intrinsically safe operation, making it suitable for use in challenging and hazardous settings.
The ingress protection ratings are IP65 for the DIN connector version, and IP67 for the M12×1 connection variant, ensuring robust sealing against dust and water ingress.
Compatible with neutral, non-flammable gases and liquids, it features a specialized brass body option for water service applications. It can handle media with viscosity levels up to 1000 mm²/s, expanding its usability.
Featuring an SPDT switch output with fixed hysteresis, the device allows for unrestricted mounting positions to accommodate diverse installation requirements.
Seal materials are selectable between NBR and FPM, with LABS-free versions available, covering the full vacuum range for versatile usage across industries.
Two electrical interface options are provided: DIN EN175301‑803 Form‑A and M12×1 IEC947‑5‑2, offering flexibility in connectivity according to system specifications.
