The APEM Panel Switches 1203MA is a reliable, normally open (NO) switch designed for seamless operation in industrial applications. With screw clamp terminals, it supports up to 8 A 125 VAC or 8 A 12 VDC with silver contacts, and 3 A 125 VAC or 3 A 12 VDC with silver-plated copper contacts. Ideal for precise control in demanding environments.
The APEM Panel Switches 1203MA is a robust, normally open (NO) panel switch engineered for reliable performance in industrial settings. Featuring screw clamp terminals and double-break contacts, this switch delivers precise control with high electrical safety standards. Its compact design (4.5 mm panel thickness) and wide operating temperature range (-20°C to +55°C) make it suitable for applications requiring durability and consistent operation under varying environmental conditions.
The APEM Panel Switches 1203MA supports a range of electrical loads with silver contacts rated for up to 4 A 250 VAC, 8 A 125 VAC, 4 A 24 VDC, and 8 A 12 VDC. Silver-plated copper contacts handle up to 2 A 250 VAC, 3 A 125 VAC, 2 A 14 VDC, and 3 A 12 VDC. Initial contact resistance is 10 mΩ max., ensuring minimal voltage drop during operation.
Engineered for industrial use, the switch operates within a temperature range of -20°C to +55°C. Its robust construction includes a panel thickness of 4.5 mm max., with total travel of 4.5 mm (NO) or 3.5 mm (NC) +/- 0.3 mm. The switch meets stringent electrical safety standards with insulation resistance of 1,000 MΩ min. at 500 VDC and dielectric strength of 2,000 Vrms 50 Hz min. between terminals and 3,000 Vrms 50 Hz min. between terminals and frame.
With an electrical life of 10,000 cycles at full load, the Panel Switches 1203MA ensures long-term performance in high-demand applications. The double-break contact design, combined with UL and CSA approvals, provides enhanced safety and reliability, making it ideal for critical industrial control systems where failure is not an option.
