The HA1R-2C6-B is a round selector switch from IDEC's H6 Series designed for 90° 2-position maintained operation with double-pole double-throw (DPDT) contact configuration. It features gold contacts with solder/tab terminal termination, providing reliable switching in heavy-duty industrial applications such as machine tools. The switch operates across a wide temperature range of -25°C to +55°C (operating) and -30°C to +80°C (storage), with operating humidity of 45–85% RH. It delivers exceptional durability with 200,000 minimum mechanical operations in maintained mode and 100,000 minimum electrical operations at 1,200 operations/hour. The device meets stringent environmental standards including IP65 protection (IEC 60529), vibration resistance to 5–55 Hz at 0.5 mm amplitude, and shock resistance to 100 m/s² (10G) operating extremes. Its robust construction and proven reliability make it ideal for control panels, machine automation, and safety-critical switching applications.
