Force-Guided Contact Mechanism
(EN50205 Class A TUV certified)
Force-guided contact mechanism detects contact welding and enables construction of safety circuits.
  • Includes mechanism so that a-contacts and b-contacts cannot close at the same time.
  • Structure maintains contact separation of at least 0.5 mm.

Gap With Other Contact When Contact Welded

  • *Below, if a-contacts are welded, then De-energized is shown; if b-contacts are welded and the nominal voltage is applied, then Energized is shown for the contact state.

Empty field: contact is in either ON or OFF state

  • *Contact gap shows initial state. Checks for the actual ON/OFF load are needed, in case movement of the contacts occurs due to opening/closing of the load.

Slim type
As the main relay body is small and slim, the plan for the circuit board can be made smaller.
  • 4 Poles Type: Length: 40 × Width 13 × Height 24 mm
  • 6 Poles Type: Length: 50 × Width 13 × Height 24 mm
Product range available with LED indicator included / built-in internal diode type
Built-in LED eliminates need for design and implementation of separate LED circuit, reducing costs and labor.
Delivers high-speed response time (8 ms or less)
The load can be stopped immediately, maintaining safety.
High shock resistance (functional shock resistance: 200 m/s2 or more)
Due to the increased shock resistance, can be used with confidence in an environment where there is vibration or shock caused by machine tools or equipment.

PC board mount socket available (4 poles / 6 poles).

Finger-safe DIN rail mount terminal sockets also available (Y type terminal, round terminal compatible) (for 4 poles / 6 poles).
