Sakae toshin FCPS22AC, FCP22A, FCP30A series potentiometers

Sakae toshin FCPS22AC, FCP22A, FCP30A series potentiometers

Overall positioning and common features of the product

The FCPS22AC, FCP22A, and FCP30A series launched by Sakae toshin are all single turn conductive plastic servo installed potentiometers, which are core compatible with precision and stability requirements for speed and voltage regulation in industrial control, automation equipment, and other scenarios. They all comply with RoHS environmental standards and have common advantages such as "oil-free metal bearings (some models)", "infinite resolution", and "low contact resistance variation". The mechanical stroke is 360 ° unrestricted rotation, suitable for continuous adjustment scenarios.

Common Special Specification Options (applicable to the entire series)

Each model supports customized specifications to meet specific scenario requirements, mainly including:

Extra tap: Supports up to 1 tap, suitable for multi gear fixed voltage/resistance output requirements.

Axis extension design: Front and rear axis extension (default diameter of 3mm for rear axle, 10mm for FCPS22A/FCP30A, 20mm for FCPS22AC), suitable for connection requirements in special installation spaces.

Limiting device: After installation, the rotation angle is limited to 320 °, and the limiting strength is 0.9N · m (9kgf · cm) for FCPS22AC and 0.3N · m (3kgf · cm) for FCP22A/FCP30A, to prevent equipment damage caused by excessive rotation.

Special electrical stroke: Non standard electrical stroke can be customized according to requirements (default 320 °± 5 ° or 340 °± 5 °).

Shaft diameter and processing: Supports special shaft diameters (such as British size of φ 3.175mm, φ 6.35mm) and special processing of shaft bodies (such as slotting, rolling, etc.).

Multi link structure: FCP22A/FCP30A supports up to 5 link structures, with an increase in shell length of 8.5mm for each additional link, suitable for multi-channel synchronous adjustment scenarios.

Precautions

Customized specification impact: If special specifications are selected (such as multi link, special shaft, customized stroke), the general specifications of the potentiometer (such as insulation resistance, torque) and environmental adaptability may change, and it is necessary to communicate and confirm with the manufacturer in advance.

Installation and use: The appropriate screws should be selected according to the installation hole size of each model (such as 2 × M2 for FCPS22AC and M3 for FCP30A) to avoid over tightening and damaging the housing; When making electrical connections, it is necessary to match the power rating (such as FCP30A maximum 1.5W) to prevent overload and burnout.

Environmental adaptation: The waterproof and dustproof levels are not clearly marked, and it is assumed to be suitable for dry, non corrosive indoor industrial environments. Additional protection is required for harsh environments.
