Description

Female connector/socket WINSTA® MIDI 3-poleFor signal and power transmission: The WINSTA® MIDI female connector/socket B coding. Whether on PCBs, in control cabinets or for connecting lights – pluggable installation connectors from WAGO allow you to make connections according to an enormous variety of requirements in next to no time. The coding options reduce installation errors, allowing fast, secure wiring of all components. The pluggable installation connector offers protection against contact with live components in accordance with protection type IP20 (When mated: IP2xC (These compact connectors are not designed for use in open, easily accessible areas!)). Pluggable installation connectors with B coding from the WINSTA® MIDI line are available in pink, light green, or gray, allowing you to distinguish different circuits, for example for pumps, lighting, or sun blinds. Your own pole marking is possible, too. This pluggable installation connector can be used for electrical currents up to 25 A. Thus the product is also suitable for high power loads. WINSTA® MIDI with Push-in CAGE CLAMP® spring pressure connection technology is found in a broad range of individual products you can use for quick, easy, flexible, and secure installation.Push-in CAGE CLAMP® spring pressure connection technology – pluggable installation instead of laborious screw connections!The WINSTA® Pluggable Connection System allows pluggable electrical installation. This significantly reduces the need for servicing and lowers costs. Choose quality and durability – with protection type IP20 from WAGO makes the electrical installation of electrical components substantially easier. pluggable installation connectors with protection against mismatingfor automation controllerswith B coding for controllers such as sun blinds and lighting fixturesexact dimensionsconvenient installation and commissioning

Specification

Notes

NoteThe snap-in connectors must be relieved of tensile and transverse forces.A surface finish can influence the edge radius of the cutouts. This may affect the snap-in socket fit, so ensure an adequate fit before use. In addition, the punched edge should be on the inside for punched cutouts.The wings of the snap-in connectors must not be mechanically stressed for a long period before use (e.g., due to a pre-locking position).
Variants:Other pole markings, Other versions (or variants) can be requested from WAGO Sales or configured at https://configurator.wago.com/.
