TK12
The difficulties in wiring caused by
the previous terminal arrangement
have been eliminated.
Previous Models
The main circuits were difficult to wire
because the screwdriver had to be held
at an angle due to interference from the
auxiliary circuits.
Downsizing
Both AC-operated and DC-operated (2.4W and 1.2W) models are available and have the
same shape as the Magnetic Contactors.
Add up to eight contacts with the addition of Auxiliary Contact Blocks (2-pole or 4-pole).
A compact, 2-pole Auxiliary Contact Blocks with a reduced depth dimension is also available.
High Reliability and Safety
Lineup includes models with bifurcated contact for high reliability (standard models) and high-
capacity models (single button contact).
Auxiliary Relays with linked contacts.(Complies with requirements of IEC60947-5-1 Annex L.)
