The HE1AN-Q-AC12V is a TM-type single-side stable power relay manufactured by Panasonic with 1 Form A contact arrangement, designed for 12V AC coil operation. This relay features a contact capacity of 30A at 250V AC resistive load and demonstrates excellent resistance to contact welding through its pre-tension and kick-off mechanism, achieving TV-15 rating. The relay offers high reliability with an electrical life of 2×105 operations at 20 cycles per minute and mechanical life of 5×106 operations at 180 cycles per minute for AC type. It provides excellent surge resistance exceeding 10,000V between contacts and coil, and is certified to major safety standards including UL, CSA, VDE, and TÜV. This relay is commonly used in office equipment such as copiers and air conditioning systems where reliable switching and long operational life are essential.
