PS-3S Omron Automation and Safety PS-3S Electrode Holder, 3-Pole, PBT Resin

The Omron Automation and Safety PS-3S is a 3-pole electrode holder designed for water level control applications in building water supply and drainage systems. As part of Omron’s PS-[]S(R) / -31 electrode holder series, the PS-3S provides a practical mounting solution for level control electrodes and allows the electrodes to be withdrawn easily for inspection and maintenance. Omron lists the PS-3S as the standard 3-pole model for general purified-water applications, used together with compatible 61F level controllers and separately purchased electrodes.

Built with PBT resin housing material, the PS-3S is lightweight and suitable for use as a built-in component in water level control systems. It supports atmospheric-pressure operation, provides 100 MΩ minimum insulation resistance, and operates across a temperature range of -10°C to +70°C with no icing.

Technical Specifications

Summary

The Omron Automation and Safety PS-3S is a 3-pole electrode holder used for conductive liquid level control, mainly in water supply and drainage systems. It is designed to work with Omron 61F level controllers and compatible F03-series electrodes, which are typically purchased separately and cut to the required length.

The PS-3S features a PBT resin body, 100 MΩ minimum insulation resistance, and an operating temperature range of -10°C to +70°C. It is commonly used in water tanks, pump control systems, purified water level detection, and building water management applications.

Sourcing Tip

When sourcing Omron PS-3S, confirm whether the project requires the standard 3-pole PS-3S or the PS-3SR 2-wire version. The “R” models include a built-in 6.8 kΩ resistor and are intended for two-wire 61F controllers, while the PS-3S is the standard 3-pole electrode holder.
