BK-6317: a compact negative coin cell battery contact for alarm and security systems
High-precision motion control with Bogen Magnetics’ miniaturized sensors
Compact design and reliability: two key requirements in modern alarm systems
As alarm, access control, and security devices evolve toward increasingly smaller form factors, electronic designers face the challenge of integrating compact components without compromising the mechanical and electrical reliability of the assembly. In coin cell battery-powered applications, contact quality is especially critical to guarantee stable long-term operation. In this context, MPD (Memory Protection Devices) adds the new BK-6317 to its catalog, a metallic negative contact designed for coin cell batteries and specifically tailored for alarm applications and small-sized electronic devices.
BK-6317: negative contact for coin cell batteries with optimized design
The BK-6317 is a negative coin cell battery contact spring made of spring steel with a nickel finish. Its main specifications include an approximate total height of 13.21 mm, an upper middle diameter of 2.54 mm, and a lower middle diameter of 3.81 mm. Furthermore, it features a total of 3 coils, a spring constant of 6.1 lb/in, and a maximum force of 0.6 lb. Additionally, the component uses 0.012″ wire gauge and is designed to facilitate soldering and PCB integration. Thus, it maintains a compact format suitable for space-constrained designs.
On the other hand, according to the manufacturer, this negative contact can be used with most CR battery sizes. Furthermore, it has been developed for contact applications in alarm systems and miniaturized electronic devices.
Security, access control, and battery-powered applications
Thanks to its compact design and configuration as a negative contact for coin cell batteries, the BK-6317 is well suited for a wide variety of security and monitoring devices powered by CR batteries. Among the applications identified by the manufacturer are door and window contacts, alarm systems, access control equipment, and other electronic security devices. The combination of a reduced size, ease of soldering, and spring-loaded contact allows engineers to simplify the mechanical integration of the battery while maintaining a reliable connection inside equipment where available space is a critical factor.
