Littelfuse Reed Relays offer high insulation resistance, low contact resistance, and a long contact life. Reed relays combine a reed switch with a copper coil, providing galvanic isolation between the coil input and the controlled contact(s). Littelfuse Reed Relays are ideal for automotive applications, test equipment, security, medical, and process control equipment.
