DZF Ultra Subminiature Basic Switch

Category: Electronics, OMRON Automation and Safety, Switches

The “DZF Ultra Subminiature Basic Switch” datasheet presents detailed information on a compact and highly durable switch designed for varied applications. This switch is notable for its small size and its snapping mechanism, which is engineered with precision using two split springs, enhancing the product’s longevity. The actuation mechanism provided by the snapping action ensures reliable operation over the switch’s lifetime.

Key Features

One distinct feature of the DZF switch is the variety of terminal options available to accommodate different mounting and connection methods. The terminals are insertion molded which is a key detail as it prevents the penetration of flux, potentially improving the switch’s performance in various conditions. The terminal variations include:

Straight PCB terminals
Self-clinching PCB terminals
PCB terminals with left and right-angled configurations
Different types of solder terminals

The switch is also noteworthy for its compliance with RoHS standards, indicating that it is manufactured with restrictions on the use of certain hazardous substances, thereby aligning with current environmental and health safety regulations.

Rating Options and Actuator Types

Availability comes in various ratings and actuator types, accommodating diverse design requirements. By default, without any suffix in the model number, the switch is rated for 125 VAC at 3A. However, a low operating force version exists, rated at 125 VAC 1A or 30 VDC 0.1A, signified by the suffix “-01”. Operating force is a critical specification and the standard force required to activate the switch is 1.47 N (150 gf), with an alternative low-force option of 0.74 N (75 gf). It should be noted that the operating force values provided are specific to the pin plunger models.

In terms of actuators, the datasheet describes various types that can be selected depending on application needs:

Pin plunger (standard)
Hinge lever
Hinge roller lever
Simulated roller levers of different radii

The different actuator types provide versatility in how the switch can be integrated into a system, enabling customization based on the movement and actuation method required.

Model Number Legend

The datasheet provides an example of how to interpret the DZF switch’s model number. An example number is broken down to display the customization options such as operating force, terminal type, and actuator style. This structured legend helps users identify and specify the exact variant needed for their application.

Conclusion

Overall, the DZF Ultra Subminiature Basic Switch offers a robust selection of options for design engineers, highlighted by its competitiveness in durability, versatility in terms of actuation and terminal types, and its commitment to RoHS compliance. These characteristics make it a potentially suitable component for a broad range of electronic applications.
