Latching Relay Magnetic Latching Version of G2A Ideal for Sequence Control • Double-winding latch system with continuous rating. • Terminals pulled from the respective junctions between the built-in diodes and set and reset coils allow the built-in diodes to be externally connected for coil surge absorption. • Excellent vibration/shock resistance with minimal secular decrease in latching power. • Easy monitoring of ON/OFF operation due to the built-in operation indicator mechanism. • Same outline dimensions as the standard models of G2A. Ordering Information Contact form Plug-in terminals Standard model Arc barrier equipped model Fully sealed model Note: 1. When placing your order, add the coil voltage rating to the model number as shown below. Example: G2AK-232A 100 VAC Rated coil voltage 2. The applicable rated voltage range can be increased by connecting an external resistor. Refer to Specifications for details. Model Number Legend G2AK-@@@@@ 1 1. Number of Poles (Contact Form) 2: DPDT 2. Contact Type 3: Crossbar bifurcated 3. Enclosure Construction 2: Casing 4: Fully sealed 4.

Safety Precautions Refer to Safety Precautions for All Relays. The G2AK can be used for special purposes by utilizing its built-in diodes. When built-in diodes are not required • With the DC-coil Latching Relay, the built-in diodes become unnecessary for a circuit in which a coil operating switch is incorporated for each of the set and reset coils as shown on the right. * Unwanted diodes • With the DC/AC-coil Latching Relay, if the junctions between the set coil and built-in diode and between the reset coil and built-in diode are connected as shown on the right, only one of the built-in...
