HE3600 Miniature Single In-line Reed Relay
Description
The HE3600 is a miniature reed relay in a SIL package with a normally open
contacts capable of switching up to 200Vdc at 10W. It is available with 5V, 12V,
and 24V coils and has external magnetic shield and diode suppressed
coil options.
Agency Approvals
Agency Agency File Number
E47258
Features
• Miniature single in-line package
• Optional coil suppression diode to
protect coil drive circuits
• Normally open contact version
• RoHS Compliant
• External magnetic shield option
• Diode suppression option
• UL Recognized to UL 508 as an
Industrial Control Switch
Benefits
• Sub-miniature size and single in line
configuration allows very high
packing densities, minimizing space
and cost
• Transfer molded package gives
maximum component protection
• Lower power coil consumption than
competing electromechanical
devices
• Hermetically sealed switching
contact is immune to the effects of
its environment
Applications
• Security Systems
• Telecom Equipment
• Process Control Systems
• Automatic Test Equipment
• Instrumentation
