HE700 Miniature Dual In-line Reed Relay
Description
The HE700 is a miniature reed relay in a DIL package with a choice of normally
open, normally open high voltage, normally closed or changeover contacts
capable of switching up to 300Vdc at 10W. It is available with 5V, 12V, and 24V
coils and diode suppression and also available with magnetic shield option.
Features
• Miniature dual in-line package
• Optional coil suppression diode to
protect coil drive circuits
• External magnetic shield option
• Diode suppression option
• RoHS Compliant
Benefits
Agency Approvals
• Hermetically sealed switching
contact is immune to the effects of
its environment
• Transfer molded package gives
maximum component protection
• One relay, various contacts choices
reducing space and cost without
compromising flexibility
• Lower power coil consumption than
competing electromechanical
devices.
