OMRON A22-DB-20A

Actuator: Roller plunger.
Conduit openings: G1/2 (PF1/2).
1NC/1NO (Snap-action).
Robust safety limit switch with metal housing.
Slow-action and snap-action contact with,
certified direct opening operation certification.
Direct opening mechanism (NC contacts only) added to,
enable opening contacts when faults occur, such as fused contacts A22-DB-20A.
Safety of lever settings ensured using a mechanism that,
engages a gear between the operating position indicator plate and the lever A22-DB-20A
Equipped with a mechanism that indicates the applicable,
operating zone, as well as push-button switching to control left and right motion.
Head seal structure strengthened to improve seal properties A22-DB-20A.
(TÜV: IEC IP67, UL: NEMA 3, 4, 4X, 6P, and 13) .
Wide standard operating temperature range: –40 to 80°C (standard type).
Certified standards: UL, CSA, EN (TÜV), and CCC.
Appearance: Round/Projection type LED lighting,
(without Voltage Reduction Unit)A22L-T.
Output: SPST-NO.
Lighting: LED.
Operating voltage: 12 VAC/VDC.
Operation: Alternate operation (self-holding) A22-DB-20A.
Illumination color: R (red); Y (yellow); G (green); W (white); A (blue) .
Install in 22-dia. or 25-dia. Panel Cutout.
(When Using a Ring).
Lever for easily mounting and removing the Switch Unit.
Increase wiring efficiency with three-row mounting of Switch Blocks.
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). Sensing distance: (See note 2.)0 to 3.5 mm(pressed position) (See note 1.).
Sensing method: Pushbutton.
Operation mode: OFF with no load.
Cable length: 1 m (robot cable).
Model: PNP output .
Using a pushbutton enables,
accurately detecting difficult-to-detec objects.
Conforms to standards for semiconductor FOUP cassettes to ena,
accurately detecting FOUP cassettes without being affectted by the,
material, collor, or reflectance of the bottoms of the cassettes A22-DB-20A.
Thin design enables mounting in a wider range of applications, e.g.,
on transfer arms.
Increased visibility with 4-direction indicator.
Optical detection of actuator operation provides a lonng life,
(mechanical life: 5 million operations min A22-DB-20A. ).
Models available with PNP or NPN output.
Models are available with very flexible robot cable.
