Summary of Omron A16 Series Pushbutton Switches Datasheet

Omron’s A16 Series of pushbutton switches is designed with a detachable and compact form factor, featuring a cylindrical 16-diameter body. This miniature design, with an industry-leading small size of 28.5 mm, maximizes space efficiency and offers versatility for various applications. The switches in the A16 series are suitable for both standard and microload contacts due to their flexible contact construction. Moreover, they provide an easy-to-wire terminal arrangement that simplifies installation procedures.

Key Features

Separate, detachable switch unit construction.
Miniature 28.5 mm design — smallest in its class.
Compatible with both standard loads and microloads.
Various models offering different terminal types: solder terminals, PCB terminals, and screw-less clamp terminals.
Multiple shapes for pushbuttons: square, rectangular, and round.
Rated for EN 60947-5-1 safety certification.

Model Variants

The A16 series includes various models differentiated by features such as terminal types (solder, PCB, voltage-reduction lighting solder, screw-less clamp), button shapes (square, rectangular, round), and lighting (lighted or non-lighted). Each model set comprises the pushbutton, lamp (for lighted models), case, and switch. Specific configurations allow for customization to meet the application requirements, with detailed ordering information available in the latter pages of the datasheet.

Customization Options

The datasheet introduces a model number structure to aid in selecting the appropriate pushbutton switch. Protection degree, contact configuration, button color, shape, light source, switch operation, rated voltage, and other attributes can be specified. For lighted models, customers can choose from incandescent lamps or LEDs with various operating and rated voltages. Custom configurations, such as alternate-operation models and choices of lighted switch colors, are also covered.

Installation and Precautions

Installation and maintenance precautions are briefly mentioned, advising readers to consult the safety precautions section for all pushbutton switches provided on page 24. It’s emphasized that solder terminals are exclusive to 100-V models and the Voltage Reduction Unit is incompatible with models featuring PCB terminals. For selecting non-standard products like those with screw-less clamp connectors, users are encouraged to contact Omron representatives to discuss pricing and delivery.

Note: Further detail and support information such as ordering information and LED clarification are available from pages 3 to 7 and page 8, respectively, of the full datasheet.
