Series Features
KSK-1A52 Series Reed Switch
Series DescriptionThe KSK-1A52 Series is a high-power, high-voltage reed switch designed for demanding applications requiring robust performance and compact form factor. With a glass body length of 21.0 mm and diameter of 2.75 mm, this SPST-NO (Form A) switch supports switching voltages up to 350 VDC and currents up to 0.7 A, with a rated power of 50 W.
Its hermetically sealed construction ensures long-term reliability in harsh environments, while the wide operate range (15–70 AT) allows for flexible magnetic actuation. The KSK-1A52 is ideal for use in high-voltage circuits, test systems, and automotive applications where precision and durability are essential.
- High breakdown voltage capability for demanding electrical environments
- Compact and rugged design suitable for space-constrained and vibration-prone applications
- Hermetically sealed contacts for enhanced protection against moisture and contaminants
- No power required for actuation, supporting energy-efficient designs
- Fast and consistent switching for precise control and timing
- Flat lead configuration for stable mounting and easy integration into automated assembly
