Installation TorqueInstallation RequirementThe Honeywell Pressure Switches, High Pressure, MediumPressure, and Low Pressure, are capable of being mounted inany orientation via a threaded port. A 27 mm hexagonal wrenchshould be used to install the pressure switch. Installation torqueshould be based on the information in Table 1. Installation ofthe pressure switch shall permit usage of maximum 27 mm hexbox spanner, modified socket wrench, and open-ended wrench.ThreadTorque (Nm)StandardM10 1.015ISO 6149-3M12 1.525ISO 6149-3M14 1.535ISO 6149-3M18 1.545ISO 6149-31/2-20 UNF25SAE J1926-39/16-18 UNF30SAE J1926-37/16-20 UNF18SAE J1926-33/4-16 UNF50SAE J1926-3, CAUTION7/8-14 UNF60SAE J1926-3PRODUCT DAMAGEG1/8 BSPP25ISO 1179-3G1/4 BSPP50ISO 1179-3INSTALLATION Use a hex wrench for installation. DO NOT exceed atorque level based on the information in Table 1. Neverapply torque to the connector housing or the body of thepressure switch. Do not subject the pressure switch to high temperatures from soldering, brazing, or welding of the systemplumbing or operating environments above the specifiedmaximum temperature.Failure to comply with these instructions could result indeath or serious injury.Ensure the power supply is off while wiring.Safety and Productivity Solutions1/4-18 NPT1/8-27 NPT1/8-27 PTFR1/8 BSPTR1/2 - 14 BSPTR1/2 BSPTR1/4 BSPT1-Screw in untilhandtight2-Then tighten the ASME B 1.20.1product by two tothree threads usingwrenchThe pressure switch can withstand a side load (actingperpendicular to the mounted axis) of 100 Newton at theend of the integral connector in its mounted orientation. Thisload requirement is for any incidental physical abuse duringinstallation or intended use.

Honeywell Pressure SwitchesOVERPRESSURERev. D50038194WIRING INSTRUCTIONS, CAUTIONNOTICEPRODUCT DAMAGETo ensure proper environmental sealing and electricalconnections when using a connector, follow the connectormanufacturer’s installation guidelines. All terminal cavitiesmust be sealed using the correct wire gauge and seal combination. If only two leads are used, any additional terminalcavities should be sealed per the connector manufacturer’sinstallation guide. Honeywell recommends using a crimpingtool for crimping wires to the connector terminals. Contactthe individual connector manufacturer for connector wiring. Do not exceed the operating pressure.Failure to comply with these instructions could result indeath or serious injury.If the operating pressure is exceeded, the life of the Honeywellpressure switch may be reduced and electrical failure mayoccur. Both static and dynamic over-pressuring must beconsidered, particularly in hydraulic system applications.Hydraulic pressure fluctuations can have very high and rapidpressure spikes, as in a water hammer effect. The high pressureversions (HP Series, HE Series) have a snubber feature built-into reduce the peak pressure applied to the pressure switch. Themedium and low pressure versions (ME Series, LP Series, LESeries) do not employ this feature.If system pressure pulses are expected, choose a pressureswitch with a proof pressure rating high enough to allowoperation at the highest expected pressure spikes.MEDIA COMPATIBILITY, CAUTIONPRODUCT DAMAGE Use non-abrasive, chemically compatible media to prevent damage to the pressure switch.Failure to comply with these instructions could result indeath or serious injury.The pressure switch’s fluid path is an assembly of zincplated steel, stainless steel, DuPont Teflon -coated Kapton ,and nitrite. The Series is compatible with a wide variety ofpetroleum-based fluids, air, water, and mineral oil-based brakefluid. Please confirm your media compatibility or speak with aHoneywell Application Engineer.2 sensing.honeywell.comFUNCTIONAL TESTConnect the pressure switch to the pressure source (off).Based on the pressure switch’s specified normally open (NO) ornormally closed (NC) output, connect the electrical terminationto a dc voltage supply. With no pressure on the pressure switch,turn on the power supply and ensure that the pressure switchis in the correct NO or NC position. Apply the appropriate setpoint pressure to ensure that the NO or NC contact position ofthe switch will switch over.
