Series Features
BT/BTS Series Reed Relay
Series DescriptionThe BT/BTS Series is a precision-engineered low thermal reed relay designed for ultra-sensitive signal switching in high-accuracy measurement systems. Featuring epoxy encapsulation and optimized thermal balancing, these relays achieve offset voltages below 1 µV, making them ideal for applications where even the smallest thermal disturbance can affect signal integrity.
Available in DPST-NO (Form 2A) configurations, the BT/BTS Series supports switching voltages up to 1,000 VDC, rated power up to 100 W, and currents up to 1.0 A. With coil voltage options of 5 VDC, 12 VDC, and 24 VDC, and coil resistance ranging from 350 Ω to 5000 Ω, these relays offer versatile integration into precision instrumentation and automated test environments. Their low thermal characteristics make them a superior alternative to semiconductor switches in ultra-low voltage applications.
