A22-TG-10M

1. Overview

The Omron A22-TG-10M is a non-illuminated, momentary pushbutton switch from Omron's A22 series, designed for 22mm/25mm round panel cutouts. It features a round extended (projecting) actuator in green, SPST-NO (1NO) contact configuration, and IP65 oil-resistant construction. The A22 series is Omron's established industrial pushbutton family with cylindrical (丸胴形) body and lever-assisted unit mounting; "T" in the part number designates projecting actuator type, "G" designates green, and "10M" encodes 1NO momentary screw-terminal configuration. Datasheet first published 1998; now confirmed discontinued by Omron.

2. User Sentiment

No community forum or end-user review data was recovered — Amazon's customer review page returned a server error. The Amazon listing title confirms the part as "Projection Type Pushbutton and Switch, Screw Terminal, IP65 Oil-Resistant, Non-Lighted, Momentary Operation, Round, Green, SPST-NO Contacts," consistent with all distributor specs. Multiple obsolete-stock specialists (Radwell, Make-Tronics) carry it with warranty offers, indicating continued MRO demand. No complaints or quality issues surfaced across the fetched sources.

3. Real-World Applications

The A22 series is widely used in industrial control panels, factory automation equipment, and machinery requiring panel-mounted momentary pushbuttons. IP65 oil-resistant construction suits machine tool environments, food processing, and installations exposed to coolants or wash-down. Chinese distributor documentation notes 3-column switch installation for improved wiring efficiency, with cable entry sealed by encapsulant, indicating use in pendant stations and operator consoles. NSN catalog and aerospace procurement listings suggest defense/industrial MRO use. Active distribution across ASEAN (Vietnam, Indonesia, Philippines) confirms ongoing industrial automation deployment.

6. Known Issues

Primary concern is discontinuation — new designs should migrate to A22NN series. EU Automation misattributes this part to ABB in their catalog (both .com and .us listings); this is a cataloging error — it is Omron only. One Chinese source (linkoing.com) appears to reference a blue-actuator variant in related A22-T series context, which could cause confusion; the A22-TG-10M is definitively green ("G" = green confirmed by Mouser, DigiKey, and all primary sources). No functional or reliability issues reported.
