HE3321C0400

Reed Relay Datasheet H3300 Miniture Single In-line Reed Relay Description The HE3300 is a miniature reed relay in a SIL package with a choice of normally open, normally open high voltage or changeover contacts capable of switching up to 300Vdc at 10W. It is available with 5V, 12V, and 24V coils and has external magnetic shield options. Features & Benefits ■ Single in-line configuration allows high packing densities, minimizing space and cost ■ Lower power coil consumption than competing electromechanical devices ■ Hermetically sealed switching contact is immune to its environment Agency Approvals Agency ■ Transfer molded package gives maximum component protection Agency File Number E47258 ■ High voltage switching version ■ Normally open and change over contact configurations available ■ External magnetic shield option ■ RoHS Compliant ■ UL Recognized to UL 508 as an Industrial Control Switch ■ Miniature single in-line package Note: Not all parts are UL Recognized. Contact Littelfuse for specific parts and agency approval ratings.
