Overview of 21SX39-T by Honeywell Sensing and Control
The 21SX39-T is a subminiature microswitch that features a single pole double throw (SPDT) contact configuration with a pin plunger actuator. It is designed to handle a maximum current of 7A and supports a maximum voltage of 28VDC. Notably, its operating force is specified as 1.39 N, and it has a pre-travel distance of 0.51 mm, which indicates the distance the actuator moves before the switch operation commences.
Manufactured by Honeywell Sensing and Control, the switch is panel mounted and designed for use with solder terminals. The body dimensions of the switch include a length of 12.7 mm, a breadth of 5.08 mm, and a height of 8.89 mm, making it compact and suitable for applications where space is at a premium. It also features momentary switch action, meaning the electrical contact is sustained only while the actuator is actively engaged.
This part is both RoHS and Pb-free compliant, ensuring it meets current environmental standards regarding the restriction of hazardous substances. Additionally, it is not REACH compliant and carries an ECCN code of “EAR99” and an HTS code of “8536.50.70.00”, permitting its exportation through general regulations.
Industry Applications for 21SX39-T
The 21SX39-T microswitch is versatile and can potentially be used across a variety of industries due to its specifications and design. Here are some example industries and applications where it could be utilized:
- Consumer Electronics: Devices like cameras, personal computing accessories, or household appliances may use microswitches like the 21SX39-T for simple, effective user input mechanisms. The compact size and reliability under frequent use make it a suitable choice for these applications.
- Industrial Automation: In automated systems and assembly lines, precise control and error-proofing are crucial. Microswitches can serve important roles in safety interlocks and position sensing for effective operation of machinery.
- Healthcare: Medical equipment often requires precise and reliable switching solutions. The 21SX39-T could potentially be used in applications where small, durable switches are needed for devices like medical imaging equipment or patient monitoring systems, contingent on specific regulatory approval for such use.
- Robotics and Drones: The capacity to withstand moderate voltage and current make this microswitch suitable for control systems in robots and drones, where reliable, repetitive triggering of actions is required.
Note that these potential industry applications are conceptual/illustrative and require analysis and verification by engineering and design teams for adherence to industry standards and specific application requirements.
