Material indications are provided on all OMRON electrodes, connection nuts, and Lock Nuts. 

Electrodes

Select an electrode appropriate for the type of liquid. Refer to Technical Guide for Level Controllers. 

Model	Material	Weight (g)	Material indication lines
F03-01 SUS304 ELECTRODE	SUS304	Approx. 170	1 line
F03-01 SUS316 ELECTRODE	SUS316		2 lines
F03-01 HAS B ELECTRODE	N10665 *	Approx. 195	3 lines
F03-01 HAS C ELECTRODE	N10276 *	Approx. 190	4 lines
F03-01 TITANIUM ELECTRODE	Titanium	Approx. 100	5 lines

* UNS No. (Unified Numbering System No.) is an international metal designation system that specifies a unique number
   for each material.

Insulated Electrodes

Electrodes are insulated with a plastic sheath to prevent them from touching each other and to isolate them from debris in the liquid.
 Before application, strip back about 10 cm of the sheath at the end to ensure sufficient conductivity. 

Model	Sheath
F03-01 SUS304 BINIL	Vinyl Tubing
F03-01 SUS304 FLUORORESIN	Fluororesin Tubing
F03-01 SUS316 BINIL	Vinyl Tubing
F03-01 SUS316 FLUORORESIN	Fluororesin Tubing

Note: Tubing comes in 1-m lengths with a sheath thickness of 0.5 mm. 

Connecting Nuts

Model	Material	Weight (g)	Material indication
F03-02 SUS304 *1	SUS303 (Equivalent to SUS304)	Approx. 12	Blank
F03-02 SUS316 *1	SUS316		6
F03-02 HAS B	N10665 *2	Approx. 20	B
F03-02 HAS C	N10276 *2		C
F03-02 TITANIUM	Titanium	Approx. 6	T

1. Spring washers made of the same material are included with the F03-02 SUS304 and F03-02 SUS316. Spring washers are not included with the other models. OMRON does not sell spring washers by themselves.
 2. UNS No. (Unified Numbering System No.) is an international metal designation system that specifies a unique number for each material.

Electrode Sets

An Electrode Set consists of an electrode, a connecting nut, and two Lock Nuts. 

Set model	Components	No. of parts in an set	Weight (g)
F03-60 SUS304	F03-01 SUS304 ELECTRODE	1	Approx. 190
	F03-02 SUS304	1
	F03-03 SUS304	2
F03-60 SUS316	F03-01 SUS316 ELECTRODE	1
	F03-02 SUS316	1
	F03-03 SUS316	2

Note: HAS and titanium Electrodes do not come in sets. 

Lock Nuts

Model	Material	Weight (g)	Material indication
F03-03 SUS304 *1	SUS303 (Equivalent to SUS304)	Approx. 2	Blank
F03-03 SUS316 *1	SUS316		6
F03-03 HAS B	N10665 *2	Approx. 5	B
F03-03 HAS C	N10276 *2		C
F03-03 TITANIUM	Titanium	Approx. 2	T

1. Only SUS304 and SUS316 Lock Nuts come with spring washers made of the same material. HAS B, HAS C and TITANIUM don't come with spring washer.
 2. UNS No. (Unified Numbering System No.) is an international metal designation system that specifies a unique number for each material.

Electrode Separators

When long electrodes are required, use Separators at each joint (every 1 m) to prevent the Electrodes from touching each other.
 Use a 1-pole Separator with BF Electrode Holders. The five-pole model can be used with PS-5S and PS-4S Electrode Holders.
 Separators cannot be used with PS-31 Electrode Holders. 

Model	No. of  Electrodes	Dimensions	Applicable  Electrode Holder	Weight (g)	Material	Operating  Temperature
F03-14 1P	1		BF-[](R)	Approx. 15	Ceramic	250 ° C max.
F03-14 3P	3		PS-3S(R)	Approx. 30
F03-14 5P	5		PS-4S(R)  PS-5S(R)

Note: The Electrode Separators cannot be used unless the Electrodes are coupled. 

Note: When using two or more Separators, be careful with the mounting direction of the connecting nut screws which connect electrodes. Avoid the screws from touching each other.
