AR22-S2-01

1. Overview

The Fuji Electric AR22-S2-01 is a 22 mm 2-position selector switch from Fuji's AR22 command-device series — a knob-operated, maintained (stay-put) rotary selector for choosing between two states (e.g. OFF/ON, Man/Auto, Hand/Off). JIS Japanese standard, also UL/CE. The S denotes the selector actuator; S2 = 2 positions. It's a complete command device (contact per the code).

2. User Sentiment

Fuji AR22 selectors are a standard, reliable 22 mm line — solid build, JIS compliance, broad availability in Fuji/Japanese-standard control gear. A 2-position maintained selector is the classic way to latch a mode selection. The main care point is matching the number of positions and the contact configuration from the exact model code.

3. Real-World Applications

Two-state mode selection on machinery and control panels — e.g. OFF/ON, Hand/Auto, Local/Remote — the maintained knob holds the selected position; the contact(s) switch the corresponding circuit.

4. Technical Specifications

• Type: Fuji AR22 2-position selector switch, 22 mm, maintained (knob)
• Contacts: 1 contact (verify NO vs NC — the "-01" code in some Fuji families = 1 NC; the catalog lists 1 NO — confirm from the datasheet)
• Cutout: 22 mm
• Sealing: IP65 (series)
• Approvals: JIS, UL, CE

5. Ordering & Compatibility

Fits standard 22 mm cutouts. AR22 selector codes carry positions and contact (S2 = 2-position; the trailing digits = contact set). Confirm positions and NO/NC from the exact code. Fuji AR22 offers 3-position selectors, key selectors, illuminated selectors, and contact blocks.

6. Known Issues

No notable reliability issues — mainstream Fuji command switch. Practical care: verify the contact configuration (NO/NC — the "-01" code warrants a datasheet check) and the number of positions, and confirm the 22 mm cutout.
