Sensata Cynergy3 Reed Switch, SPST Contact Configuration, 10VA Switching Power - TRA294G/20-30
Use this tiny but tough reed switch from Sensata Cynergy3 for high-speed switching applications. Thanks to an operating time of 2ms and a maximum release time of just 0.05ms, you can rest assured you'll get rapid-fire switching. Its wide operating temperature range of -40°C to +150°C means it will hold up when the heat is on. Reed switches like this one are commonly found in medical equipment, security screening systems or automotive applications such as door sensors.
Features & Benefits
• Switching voltage of 150V AC/DC for use in low-power systems
• Rhodium contact material offers low contact resistance and high conductivity for reliable switching
What are the dimensions of this product?
The reed switch has compact dimensions of 55 (L) x 2.3mm (D), as well as a wire diameter of 0.5mm. This makes it easy to install in tight spaces.
How does a reed switch work?
A reed switch is a type of electrical switch that's actuated by magnetism. The thin, flexible metal wires known as reeds are drawn together by magnetic forces, thereby closing the circuit.
