The APEM Panel Switches 5239MAKB are single pole autoswitches designed for robust industrial applications. These switches feature nickel-plated contacts, 1.000 Vrms 50 Hz dielectric strength, 50.000 cycles electrical life, and operate within -40°C to +85°C temperatures. Ideal for panel mounting with PCB terminals or bushing options, they offer reliable switching performance in demanding environments.
The APEM Panel Switches 5239MAKB are single pole autoswitches engineered for high-reliability industrial use. With nickel-plated contacts and a robust construction, these switches deliver precise ON/OFF functionality across extreme temperature ranges (-40°C to +85°C). The product combines high electrical performance, including 1.000 Vrms 50 Hz dielectric strength between terminals and 10 mΩ max initial contact resistance, with exceptional durability through 50.000 cycles of electrical operation. Designed for both panel mounting and PCB terminal integration, the 5239MAKB ensures seamless compatibility in critical control systems while maintaining UL and CSA approvals for safety and compliance.
The APEM Panel Switches 5239MAKB deliver precise electrical switching with a minimum dielectric strength of 1.000 Vrms 50 Hz between terminals and 1.500 Vrms 50 Hz between poles. Initial contact resistance remains below 10 mΩ max, ensuring low power loss during operation. Contact bounce is limited to 2 ms max, minimizing transient effects in switching circuits.
Engineered for extreme conditions, these switches operate reliably across a wide temperature range from -40°C to +85°C. This robust thermal performance ensures consistent functionality in both harsh industrial environments and temperature-sensitive applications without degradation.
With 50.000 cycles of electrical life at full load and 100.000 cycles for mechanical life, the 5239MAKB provides extended service life in demanding applications. The switches are designed to withstand repeated switching operations without significant performance decline.
Available in both panel mounting and PCB terminal configurations, the 5239MAKB supports flexible installation requirements. The bushing Ø 11.9 (15/32) ensures secure mounting while maintaining compatibility with standard industrial panel designs.
