Ratchet Relay Unique Ratchet Mechanism Assures Positive Alternate Transfer/Switching Operation • Each contact in the double-pole contact mechanism performs alternate make-brake operation at each pulse input and is thus ideal for alternate operation or transfer/switching operation of a motor. • Positive operation is assured due to the unique ratchet mechanism. • Satisfies dielectric strength of 2,000 VAC. • Low power consumption. (AC: approx. 6.4 VA; DC: approx. 3.9 W) Ordering Information Open Models Plug-in Models DPDT Model Basic model Model Basic model When ordering, add the rated coil voltage (listed in Specifications) to the model number.

Plug-in Terminal Model Terminal Arrangement/ Relay Mounting Height with Socket With Front-connecting With Back-connecting Socket Socket Safety Precautions Refer to Safety Precautions for All Relays. ■ Surface Mounting Socket Be sure to provide a mounting space according to the width of the Relay. The width of the Relay is 63.5 mm and the width of the Socket Mount the Relay so that the coil faces upward and the cam faces downwards with the mounting plate secured vertically. Do not Make sure that Relay terminals are free of flux or any other foreign substance before soldering the Relay terminals....
