Product Description:
NORGREN 18D Series Electro-Mechanical Pneumatic Pressure Switch
The NORGREN 18D Series (Model 0880 / 0881) is a reliable diaphragm-actuated pressure switch designed for industrial automation applications. It serves as a pressure monitor for alarms, interlocks, and loop control systems. Manufactured by IMI Norgre, this series accommodates a wide pressure range from vacuum conditions up to 30 bar working pressure. Users can choose from multiple port options including G1/4, 1/4 NPT, and flange mounting to suit various installation requirements.
For electrical connections, two options are available: the DIN EN 175301-803 Form-A and the M12×1 IEC 947-5-2 connectors. Additionally, there are LABS-free variants and brass-body special versions specifically designed for water service. These configurations make the switch suitable for neutral gases, liquids, and water-based media operating conditions.
The pressure switch is equipped with a gold-plated contact microswitch certified by UL and CSA, ensuring intrinsically safe operation. It also withstands vibrations up to 15 g. The device boasts a mechanical service life of up to 10 million switching cycles, offering excellent repeatability. While the standard housing is made of aluminum alloy, models intended for water applications use brass housing. Seal options include NBR and FPM materials. The switch can achieve a maximum ingress protection rating of IP67, making it ideal for harsh industrial environments.
When the system pressure reaches the preset set-point, the SPDT micro-switch delivers an electrical signal that can be used for machine interlock, alarms, or on/off control in pneumatic machines, hydraulic circuits, and water treatment equipment.
Note: It is recommended that set-points be selected near the midpoint of the pressure range. Do not exceed the rated pressure indicated on the nameplate. Inductive loads require spark-quenching protection circuits. Connectors are sold separately; DIN or M12 plugs are not included.
Features:
Experience the authentic quality of NORGREN IMI with the comprehensive 18D‑0880 product range, offering multiple pressure ranges and a variety of port options to suit diverse applications.
These diaphragm-operated devices function 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, the products hold UL and CSA approvals and boast a mechanical lifetime of up to 10 7 switching cycles, highlighting their durability and long-term usability.
Designed to endure high vibration environments with resistance up to 15 g, they also support intrinsically safe operation, making them suitable for challenging and hazardous settings.
The ingress protection ratings include IP65 for the DIN connector and IP67 for the M12×1 connection, ensuring robust protection against dust and moisture.
These devices are compatible with neutral non-flammable gases and liquids, featuring a dedicated brass body variant specifically for water service applications. They can handle media viscosity up to 1000 mm²/s, broadening their scope of use.
Featuring an SPDT switch output with fixed hysteresis, these switches allow unrestricted mounting positions. Seal materials are selectable between NBR and FPM, with LABS-free versions available to cover the full vacuum range.
Two electrical interface options are provided: DIN EN175301-803 Form-A and M12×1 IEC947-5-2, offering flexibility in integration with various systems.

Applications:
Pressure monitoring and alarm systems play a crucial role in industrial pneumatic automation. These systems ensure safe and efficient operation by continuously tracking pressure levels and triggering alarms when abnormal conditions arise.
Additionally, compressor and vacuum pump setups benefit from pressure interlock protection, which helps prevent equipment damage by automatically controlling operational sequences based on pressure feedback.
In hydraulic fluid power systems, pressure signal feedback is essential for maintaining stability and precision. This feedback allows for accurate control and adjustment of hydraulic operations to meet specific performance requirements.
Water-treatment and water-supply equipment, especially those utilizing brass water-service variants, also rely on specialized pressure monitoring devices to ensure reliable and contamination-free service.
Pressure detection is vital in packaging machinery, machine tools, and conveyor equipment, where maintaining consistent pressure levels directly impacts product quality and operational safety.
Over-pressure alarm systems combined with machine start-stop controls are widely used in industrial fluid pipeline networks. These mechanisms safeguard the infrastructure by preventing excessive pressure buildup and controlling machine operation accordingly.
Lastly, general-purpose machinery often incorporates vacuum monitoring and control functions to optimize performance and protect sensitive components from vacuum-related issues.
