Output: SPST-NO + SPST-NC.
Operation: Alternate operation (self-holding).
Illumination color: R (red); Y (yellow); G (green);
W (white); A (blue); B (black).
Install in 22-dia. or 25-dia. Panel Cutout.
(When Using a Ring).
Lever for easily mounting and removing the Switch Unit OMRON A2A-4G.
Increase wiring efficiency with three-row mounting of Switch Blocks A2A-4G
Finger protection mechanism on Switch Unit provided as a standard feature.
Use 25-dia. ring to install in 25-dia. panel cutouts.
Mounted using either open-type (fork-type) or closed-type.
(round-type) crimp terminals.
IP65 oil resistance (non-lighted models).
IP65 (lighted models). Output configuration: NPN open collector (- common) OMRON A2A-4G.
Contact form: SPST-NO.
Operation indicator: ON when operated.
Cable length: 3 m.
Optical System Achieves 1-μm Operating Position.
Repeatability in this 4-way Switch.
No-contact structure for high reliability.
Ceramic materials in measuring part for superior resistance to abrasion.
Two different output types (PNP and NPN) available. ,
Less abrasion and damage of mechanical contacts compared,
to switches with contacts, reducing fluctuation in the output OMRON A2A-4G.
More compact than previous OMRON models: 40% less mass,
15% lighter across the operating width. Appearance: Knob-type Selector Switch A22W,
LED voltage-reduction lighting (without Voltage Reduction Unit).
