Features
PFA enclosure gives excellent chemical resistance [EX-F60]
The sensor enclosure and the cable sheath are made from PFA which is highly resistant to chemicals. Accurate sensing is achieved even if there are leaks of chemicals such as sulfuric acid, hydrochloric acid or ammonia.
Easy installation & reset [EX-F60]
The simplified shape makes it easy to clean up after liquid leaks, simply by wiping off the liquid, and no parts need to be replaced.
Compact, space-saving [EX-F60]
Even with its built-in amplifier, the size is compact at W26 x H19 x D9 mm W1.024 x H0.748 x D0.354 in, so that it can be used even in narrow spaces.

Wire-saving unit made especially for connecting leak detection sensors! [EX-FC1]
- Saves wiring! Connects up to 8 leak detection sensors
EX-FC1 is a simple wire-saving unit for exclusive use with EX-F71/72, EX-F61/F62 leak detection sensors. (It can be used with general sensors as well.)
EX-FC1 integrates the outputs from up to 8 leak detection sensors into a single OR output, so significant wiring and space savings are achieved.
* Even with only one leak detection sensor connected, an OFF signal is output if the sensor detects liquid leakage, or if the unit has been installed incorrectly.
- Slim & compact
Space savings are significant, as the ultra-thin & compact EX-FC1 has main unit body dimensions of only W20 x H80 x D52 mm W0.787 x H3.150 x D2.047 in.
- Connects easily with one-touch connector Connections are made by simply inserting the leak detection sensor cable leads into the snap male connector SL-CP1, then push until the connector snap-locks! This saves the time and the trouble of stripping the insulation from each lead before attaching to terminals.

Mounting
EX-F71(-PN)
- Insert the M4 stud-bolt (length 10 mm 0.394 in or more) welded on the user’s facilities into the mounting hole of the SUS mounting bracket and screw with an M4 nut (please arrange separately). The tightening torque should be 0.98 N·m or less.
EX-F72(-PN)
- Insert M4 stud-bolts (length 10 mm 0.394 in or more) welded on the user’s facilities into the mounting holes of the two-point-fixing mounting bracket and screw with M4 nuts (please arrange separately). The tightening torque should be 0.49 N·m or less.
- Use adhesive to stick fast the mounting bracket on the mounting surface. Please note that if the adhesive sticks out from the bottom surface of the mounting bracket or is 0.5 mm 0.020 in, or more thick, the sensor body cannot be fitted to the mounting bracket.
- Match the notch in the sensor body with the projection of the exclusive mounting bracket and slide till a click is felt.
- When mounting, make sure to use the brackets included with the unit in order to eliminate human error (such as forgetting to install). If the included brackets are not used, stable sensing is rendered impossible. Also, because sensitivity settings differ between the EX-F71(-PN) and the EX-F72(-PN), their brackets cannot be interchanged.

Operation matrix for each indicator
| Operation | Connection state of the leak detection sensor | State of the connection setting switch | Leak detected condition | Normal indicator (Green) | Error indicator (Red) | Output indicator (Orange) |
|---|---|---|---|---|---|---|
| Normal | Connected | ON | Not leaked | Lights up | Turns off | Lights up |
| Leaked | Turns off | Lights up | Turns off | |||
| Unconnected | OFF | － | Turns off | Turns off | Lights up | |
| Error | Connected | OFF | Not leaked | Lights up | Lights up | Turns off |
| Unconnected | ON | － | Turns off | Lights up | Turns off |
- For the channel that the unit sensor is connected to and the connection setting switch is set to “ON” side, the error indicator (red) lights up for a moment when the power is turned on. This is not a malfunction for the unit because it is caused by characteristic of the sensor.
- Make sure to set the connection setting switch with the connector No. to which the leak detection sensor is connected, to “ON” side.
- In case both the normal indicator (green) and the error indicator (red) light up, the connection setting switch with the connector No. to which the leak detection sensor is connected, is not set to “ON” side. Set the connection setting switch with the connector No. to which the leak detection sensor is connected, to “ON” side.
- In case the error indicator (red) lights up, the leak detection sensor detects leak or the connection setting switch is set to “ON” side without connecting the leak detection sensor. If the connection setting switch is set to “ON” side without connecting the leak detection sensor, set the connection setting switch to “OFF” side.
- If the leak detection sensor detects leak or the connection setting switch is set to “OFF” side in the state that the leak detection sensor is improperly mounted to the mounting bracket, the sensor judges as the output is ON. Be careful when setting.
All models
Wiring
- Make sure that the power supply is off while wiring.
- Verify that the supply voltage variation is within the rating. Take care that if a voltage exceeding the rated range or an AC power supply is directly applied, the sensor may get damaged or burnt.
- If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
- In case noise generating equipment (switching regulator, inverter motor,etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground.
- Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.
- Make sure to use an isolation transformer for the DC power supply. If an auto-transformer (single winding transformer) is used, this product or the power supply may get damaged.
- In case a surge is generated in the used power supply, connect a surge absorber to the supply and absorb the surge.
- Cable extension is possible up to total 50 m 164.05 ft with 0.3 mm2, or more, cable (less than 10 m 32.81 ft for EX-FC1). However, in order to reduce noise, make the wiring as short as possible.
- Make sure that stress by forcible bend or pulling is not applied directly to the sensor cable joint.
- EX-FC1 output dose not incorporate a short-circuit protection circuit. Do not connect it directly to a power supply or a capacitive load.
Others
• Avoid using the product in an explosive atmosphere because this product does not have an explosive-proof protective construction.
• When liquid remains on the sensing surface after leak detection, wipe all liquid from the sensing surface. To avoid scratching the sensing surface and the enclosed mounting bracket, use a soft cloth.
- In case air bubbles are drawn into the sensing part, take care that it may take some time for sensing to stabilize, or sensing may even become unstable. Check the usage conditions thoroughly before use.
- Do not use during the initial transient time (leak detection sensor: 50 ms approx., EX-FC1: 0.5 sec. approx.) after the power supply is switched on.
- Since this sensor employs non-modulated infrared LED, take sufficient care against extraneous light. Do not expose the sensing part directly to the extraneous light.
- Avoid dust, dirt, and steam. Further, do not use this product in an environment containing organic solvents.
- Take care that EX-7□(-PN) and EX-FC1 does not come in contact with oil, grease or organic solvents, such as, thinner, etc.
- In case this sensor is used where electrostatic charge is present, use a metal leak pan, which should be connected to an actual ground.
- These sensors are only for indoor use.
