HF SERIES REED RELAY

Product catalog summary

Overview: The document is a datasheet for HF Reed Relays, highlighting their design, development, and manufacturing by Standex-Meder. These relays are used in various applications such as telecommunications and aerospace.

Features: The HF Reed Relays are characterized by high RF/power capabilities and patented external electrostatic and magnetic shields.

Applications and Markets: These relays are suitable for telecommunications, HF tuned antennas, aerospace, marine, and other markets.

Technical Specifications:

Contact Data: Rated power is 25 W, with a maximum switching voltage of 500 V and a switching current of 1.5 A. The contact resistance is 150 mOhm, and the breakdown voltage is 10 kVDC.
Environmental Data: The relays can withstand shock resistance up to 50 g and vibration resistance up to 20 g. Operating temperatures range from -40 to 85 °C, with storage temperatures from -40 to 105 °C.
Coil Data: Nominal coil voltages are 5, 12, and 24 VDC, with varying coil resistances and power ratings depending on the contact form and switch model.

Handling and Assembly Instructions: Protective circuits are necessary for switching inductive or capacitive loads. External magnetic fields and mechanical shocks should be considered to avoid relay failure. Soldering guidelines include a maximum temperature of 260°C for 5 seconds.

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.
