Snap Action, Limit Switches: DS1F5BQ1 application field and working principle

The DS1F series of snap action, limit switches are general purpose switches designed for use in toggle, biasing and other applications. They come with a wide range of body sizes, actuator types and contacts, suiting a variety of requirements.

These switches are highly reliable, with sealed construction and contact blocks suitable for washdown conditions. They are also designed with functionally stable operating conditions, and are available with silver or gold-platted contacts.

Application and Uses

The DS1F5BQ1 limit switch is typically used for toggle switch applications where moving and stationary parts require precise positioning when engaging. It can also be used for biasing applications, as well as for position sensing for machine tools and production lines. It is a great option for use in harsh environments such as factory automation and robotics, as it is made of reinforced plastic for superior environmental resistance.

Working Principle

The DS1F5BQ1 limit switch works based on the principle of a snap action mechanism. When the limit switch is activated, the actuator moves downwards and engages the contact, which opens or closes the switch. The switch opens or closes at an adjustable angle, depending on the type of actuator; the contact angle can be adjusted by turning the adjustment screw. The actuator remains in the position of the contact when released and the reset spring pushes the actuator back to its original position, ready for the next actuation.

The DS1F5BQ1 limit switch has a robust construction designed to withstand extreme mechanical and environmental stresses. It is available with both continuous and momentary contact options, with an adjustable activation angle of 0.5 to 11 degrees. The switch has a wide operating temperature range from -20 to +70 degrees Celsius, making it suitable for a variety of applications.

Conclusion

The DS1F5BQ1 limit switch is a great option for position sensing, toggling and biasing applications, as it is made of reinforced plastic for superior environmental resistance. It works on the principle of a snap action mechanism, with adjustable activation angles from 0.5 to 11 degrees. It is highly reliable, with seal construction and contact blocks suitable for washdown conditions and a wide operating temperature range. It is suitable for use in a variety of harsh environments such as factory automation, robotics and production lines.
