K5V系列轻触开关

  新型K5V4开关采用高温PAR(聚芳酯)材料制造,热变形阈值为250℃,非常适合从波峰焊工艺过渡到回流焊接工艺的制造商。该开关无需硅胶套或特殊处理,首次实现直接SMT组装,从而降低生产成本,提高产量,提升最终产品质量,同时还保持耐用性和触感性能。

  Littelfuse开关与传感器工程副总裁Jeremy Hebras表示:“该款新型K5V4开关专为满足当今紧凑型电子系统的需求而设计,在这些系统中,空间效率、可靠性和用户界面反馈至关重要。K5V开关产品系列旨在满足客户独特的设备架构需求,在这种架构中,主板和组件的位置与前面板成90°角。结合长行程、敏锐触感和背光功能,K5V是需要精确设备控制的理想选择,尤其是在防止意外驱动或缺乏即时用户反馈的情况下。”

  主要功能与特色:

  · 通过PAR材料兼容回流焊接,无需套管;

  · SPDT触点配置,提供常开和常闭选项;

  · 敏锐的触觉响应,可听到咔嗒声,具有4N操作力;

  · 集成高亮度LED,有多种颜色和双色可供选择;

  · 紧凑型防尘设计,可在密集电路板内可靠运行;· 镀金圆顶触点,具有出色的长期触点性能;

  · 提供SMT(GH)和THT(PIP)版本,设计灵活。

  市场与应用:

  · 数据中心和服务器:系统控制和诊断界面按钮;

  · 网络基础设施:路由器和电信设备复位和反馈开关;· 工业设备:控制面板界面、安全复位点和信号输入;

  · 专业音频/视频系统:为混音器、配电板和低光界面提供触感响应。

  Littelfuse推出的首款采用回流焊接SMT封装的长行程、SPDT、发光轻触开关,填补了市场上一项关键空白。相比之下,市场上其他同类产品通常需要波峰焊接,增加了装配工艺的复杂性和成本。K5V4系列将卓越的人体工程学、视觉反馈和可制造性结合在一个紧凑、坚固的解决方案中。

  这一扩充强化了Littelfuse对推动轻触开关技术发展的承诺,为OEM提供针对现代生产环境优化的高性能人机界面(HMI)组件。
