Miniature relay, power miniature relay

Highest switching safety on smallest space

If it is necessary to switch heavy currents reliably in a small space and galvanic separation of control and load circuits is also required, there is no better answer than the compact miniature power relays available in SMD (Surface Mount Device) form and in DIL (Dual In-Line) form. With the smallest of dimensions, at around 20 mm long and 10 mm wide, they can be inserted into conventional 16-pole IC sockets.

All miniature relays are optionally available as versions with one NO contact or with one changeover contact. Different technologies, contact materials and contact configurations show their strengths in various applications.

Miniature relays in different designs, contacts and materials.

The miniature relays OW 5691, OW 5699 also have an overall height of only 12.15 mm and find their place in almost any environment. Characteristic of the wash-tight miniature relays known under the DILAIS brand is their high switching capacity, wide operating voltage range and reliability.

Thus, the monostable power miniature relay OA 5690 is always used when there are the highest requirements for galvanic isolation between the control and load circuits. Clearances and creepage distances ≥ 8 mm between coil and contact as well as low coupling capacitances make this relay the ideal component.

In the OR 5691 remanence relay, the contacts also remain in the active position after a current pulse by utilizing the existing residual magnetism (remanence) until a reduced pulse occurs in the opposite direction of current flow. Thus, this relay is also used when the self-heating of the coil and the energy consumption are to be reduced to a minimum.

Dold's miniature relays are characterized by their smallest dimensions combined with high performance and reliability. For example, the relay minis measure just 10 x 20 x 12 mm. However, the switching contacts easily cope with continuous currents of up to 8 A. In addition, the user can choose between different contact materials and designs. Typical areas of application are:

  • Automation and process technology
  • Measurement and monitoring technology
  • Installation and power engineering
