Product Description

Johnson Controls - PENN F261MAH-V01C Liquid Flow Switch

The F261 Series Flow Switches respond to fluid flow in lines that carry water, ethylene glycol, or other nonhazardous fluids. These models also work in applications with swimming pool water and lubricating oils.

F261 Series Standard Flow Switches use a variety of paddle sizes to respond to fluid flow rates in applications with 1 inch or greater trade size pipe. F261 Series Low Flow Switches respond to low fluid flow rates in applications with 1 inch or less trade size pipe.

A low-energy model with gold-plated contacts provides improved electrical performance in low-voltage, low-current circuits (dry circuits) to switch low-energy resistive loads, such as control signals.

Features and Benefits

Type 3R (NEMA) or Type 4 (NEMA) polycarbonate enclosure
Provides dust protection in indoor and outdoor applications.
Viton® diaphragm Facilitates use in fluid lines that carry chlorinated water, treated water, or other nonhazardous fluids.
Low-flow operation on low-flow models Actuates switch with less than 2.0 GPM (7.6 L/min) flow for water applications or 11.0 GPM (41.6 L/min) flow for steam applications.
Gold-plated contacts on selected models Reduce intermittent contact problems in low-voltage and low-current circuits (dry circuits).
Maximum fluid pressure of 290 psig (20 bar) Facilitates use in a wide range of pressure flow conditions.

Technical Specifications

Switch: single-pole, double-throw (SPDT)
Enclosure: UL: Type 3R or Type 4 CE: IP43 (IP23 with drain hole plug removed) or IP67
Wiring connections: Three color-coded screw terminals and one ground terminal
Conduit connection: One 7/8 in. (22 mm) hole for 1/2 in. trade size (or PG16) conduit
Pipe connector: Standard: 1 in. 11-1/2 NPT Threads Low-Flow: 1/2 in. x 1/2 in. Female NPTF; 3/4 in. x 3/4 in. Female NPTF
Maximum fluid pressure: 290 psi (20 bar
Minimum fluid temperature: -20°F (-29°C) Note: Ensure that the low liquid temperature combined with the low ambient temperature does not lead to freezing the liquid inside the body or, if applicable, the bellows. Observe the liquid freezing point.
Maximum fluid temperature: 250°F (121°C) Note: At higher ambient temperatures, the maximum liquid temperature becomes lower. The temperature of the electrical switch inside should not exceed 158°F (70°C).
Ambient conditions: -40°F to 140°F (-40°C to 60°C)
Country of Origin (subject to change): Mexico

Additional Information

Application

All F261 Series Flow Switches are intended to control equipment under normal operating conditions. Where failure or malfunction of an F261 Flow Switch could lead to an abnormal operating condition that could cause personal injury or damage to the equipment or other property, other devices (limit or safety controls) or systems (alarm or supervisory) intended to warn of, or protect against, failure or malfunction of the F261 Flow Switch must be incorporated into and maintained as part of the control system.
Do not install or use this F261 Series Flow Switch in or near environments where corrosive substances or vapors could be present. Exposure of the F261 Series Flow Switch to corrosive environments may damage the device’s internal components and will void the warranty.
Do not use F261 Series Flow Switches where the fluid in the pipes drops below the fluid’s freezing point, causing an internal freeze-up.

Standard flow switches

Use the F261 Series Standard Flow Switches in applications with fluid pressures up to 290 psig (20 bar). In a standard application for a standard F261 flow switch, shut down the refrigeration compressor on a fluid chiller system if flow stops. This reduces the chance of chiller freeze-ups.

Low-flow switches

The F261 Series Low-Flow Switches have 1/2 in. Female NPTF or 3/4 in. Female NPTF inlet and outlet connections.

Use F261 Low-Flow Switches in applications where flow rates are low, such as:

Water purification and treatment systems.
Booster pumps.
Cooling systems for electronic tubes, bearings, and compressors.
In rapid recovery water heaters to start the water heater when water withdraws.

The performance specifications are nominal and conform to acceptable industry standards. For applications at conditions beyond these specifications, consult the local Johnson Controls office or representative. Johnson Controls shall not be liable for damages resulting from misapplication or misuse of its products.
