Omron, A22NS/ A22NW Series

last update: October 03, 2016

Easy to Use

• Improved wiring visibility through to a modified wiring direction. (Push-In Plus terminal block type)
• Screw terminal block structure is compatible with round crimp terminals. (Screw terminal block type)
• The terminals can be secured even when a contact block is mounted. (Screw terminal block type)

Miniaturization

• No need for extra lateral space because of the modified wiring direction. (Push-In Plus terminal block type)
• Compact design.
• A22NL (lighted models) are the same size as A22NN (non-lighted models).

Safety

• Easy-to-operate lock lever for secure locking.
• Easy-mounting Contact Blocks provide finger protection.
• No loose connections of wiring means maintenance-free use. (Push-In Plus terminal block type)

Product Lineup

• Meet global safety standards.
• Can be installed in two types of panel hole dimensions: 22.3 and 25.5 dia.
• The buttons and bezels come in a wide variety of colors, shapes, and materials.
• Standard-feature degree of protection: IP66, NEMA 4X, and NEMA 13.
