Note: 1. For the DC models, check the coil polarity when wiring and wire all connections correctly.
2. The indicator is red for AC and green for DC.
3. The operation indicator indicates the energization of the coil and does not represent contact operation.

LY1-0, LY3-0,
LY2-0, and LY4-0
Note: The figures and dimensions depicted here are for the LY2-0.
The dimension with an asterisk (*) is 6.4 for the LY1-0.
Note: 1. The dimensional tolerance is 0.1 mm.
2. There are exposed parts (conductive parts) on the LY1-0
other than the terminals. Be careful when using this Relay
on a double-sided PCBs.
