OA 5621 OA 5622

Applications

• To be used in electrical circuits for safety applications

• Escalators and walkways

• Elevators for men and load

• Press controls

• Railway technology

• Medical technology

Technical Data

Gold plated double contacts

see seperate datasheet

• Acc. to DIN EN 50205, DIN EN 61810-1, DIN EN 60664-1

• With forcibly guided contacts

• Low rated power consumption

• Clearance and creepage distances ≥ 5.5 mm;

that means double and reinforced insulation between all circuits

• High mechancial service life

• High temperature range

• High thermal continuous current

• Extremly flat: only 15.5 mm high

• Version with double contacts possible, AgNi 0.15 + 5 µm Au-contacts
