UMS SERIES REED RELAY

Product catalog summary

Overview: The UMS Series Reed Relays are ultraminiature single-in-line relays designed for use in PCB test systems, automated test systems, and closely stacked matrices. They are applicable in markets such as test and measurement, telecommunication, and security.

Specifications:

Contact Data: Rated power is 10 W, with a maximum switching voltage of 170 V and a maximum switching current of 0.5 A. The contact resistance is capped at 200 mOhm, and the breakdown voltage is at least 0.210 kVDC.
Coil Data: Nominal coil voltage is 5 VDC with a typical coil resistance of 400 Ohm. The pull-in voltage is a maximum of 3.75 VDC, and the drop-out voltage is a minimum of 0.5 VDC.
Environmental Data: The relays can withstand a maximum shock resistance of 50 g and vibration resistance of 20 g. 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.

Contact Forms: The datasheet describes three contact forms: Form A (Normally Open, SPST), Form B (Normally Closed, SPST), and Form C (Changeover, SPDT).

Handling & Assembly Instructions:

Protective circuits are necessary when switching inductive or capacitive loads to prevent damage from voltage or current peaks.
External magnetic fields and high packing density can affect electrical characteristics.
Mechanical shocks, such as dropping, can cause failures.
Wave soldering should not exceed 260°C for 5 seconds, and reflow soldering should follow the soldering paste manufacturer's recommendations.
