BT SERIES REED RELAY

Product catalog summary

Overview: The document is a datasheet for the BT Series Reed Relays by Standex-Meder, a leader in sensor and magnetic component manufacturing. It highlights the features, applications, and technical specifications of the BT Reed Relays.

Features: The BT Reed Relays are characterized by low thermal voltage, high insulation resistance, and high voltage capabilities. They are suitable for high precision measuring devices and as changeover switches for resistance thermometers.

Applications and Markets: These relays are primarily used in test and measurement markets, among others.

Technical Specifications:

Contact Data: Rated power is 10W, with a maximum switching voltage of 200-500V and a switching current of 0.5A. The contact resistance is between 150-200 mOhm, and the breakdown voltage ranges from 0.225 to 0.6 kVDC.
Environmental Data: The relays can withstand a maximum shock resistance of 50g and vibration resistance of 20g. Operating temperatures range from -20 to 85°C, with storage temperatures from -35 to 100°C. The maximum soldering temperature is 260°C for 5 seconds.
Coil Data: Nominal coil voltages are 5, 12, and 24 VDC, with corresponding coil resistances and power ratings provided. The pull-in and drop-out voltages vary with temperature changes.

Handling and Assembly Instructions: Protective circuits are necessary for switching inductive or capacitive loads to prevent damage. External magnetic fields and mechanical shocks should be considered to avoid relay failure. Soldering recommendations include wave soldering at a maximum of 260°C for 5 seconds and following reflow soldering guidelines from the solder paste manufacturer.

Contact Forms: The document explains different contact forms: Form A (Normally Open), Form B (Normally Closed), and Form C (Changeover).

Additional Information: The datasheet includes contact information for Standex-Meder's offices in the USA, Europe, and Asia, and notes that technical modifications may occur.
