The APEM Panel Switches 661/2 are four-pole, solder lug terminal switches designed for industrial applications. These robust switches offer a maximum current rating of 10 A at 30 VDC with resistive loads, and a dielectric strength of 2,500 Vrms 50 Hz. They provide reliable electrical performance with an initial contact resistance of 10 mΩ max and electrical life of 10,000 cycles at full load, ensuring durability in demanding environments.
Product Overview
The APEM Panel Switches 661/2 are high-performance four-pole switches engineered for industrial control systems. These switches feature solder lug terminals and are designed to operate within a temperature range of -20 °C to +55 °C (-20 °F to 131 °F), making them suitable for harsh environments. With a dielectric strength of 2,500 Vrms 50 Hz and insulation resistance of 1,000 MΩ min. at 500 VDC, they ensure reliable electrical isolation and safety. The switches also deliver a maximum current rating of 10 A at 30 VDC for resistive loads, with an electrical life of 10,000 cycles at full load, providing long-term operational stability in critical industrial applications.
Electrical Performance
The APEM Panel Switches 661/2 deliver precise electrical performance with a maximum current rating of 10 A at 30 VDC for resistive loads. For inductive loads, this rating decreases by 50%, ensuring compatibility with a wide range of industrial applications. The initial contact resistance is limited to 10 mΩ max, minimizing voltage drop and heat generation during operation. With an electrical life of 10,000 cycles at full load, these switches maintain consistent performance over extended periods in demanding environments.
Environmental and Safety Ratings
Engineered for extreme conditions, the Panel Switches 661/2 operate within a temperature range of -20 °C to +55 °C (-20 °F to 131 °F), making them suitable for both cold and hot industrial settings. The switches feature a dielectric strength of 2,500 Vrms 50 Hz and an insulation resistance of 1,000 MΩ min. at 500 VDC, ensuring robust electrical isolation and safety compliance even under high-voltage conditions.
Installation and Torque Requirements
Installation of the Panel Switches 661/2 requires precise torque application of 1.50 Nm (1.10 Ft.lb) max. to the nut, ensuring secure and reliable connections without over-tightening. The solder lug terminals provide a straightforward installation process for PCB and panel mounting, reducing assembly time and potential errors.
