Binder 620 Series Circular Connector, 4Pole Contact Count, 2.5A Current Rating - 99-9210-00-04

This circular connector provides a compact, sealed connection solution for cable-mounted systems in industrial settings. It is designed for low-voltage signal and power distribution where a durable, weather-resistant Interface is required. The connector is intended for straight cable installations with a snap-in mating mechanism and a female contact arrangement to link with compatible counterparts.

Features and Benefits:

• Four electrical contacts delivering 2.5 A current capacity per contact
  Gold-plated bronze contacts reduce contact resistance and corrosion
  Polyamide enclosure offers mechanical robustness and chemical resistance
  IP67 sealing enables immersion and dust-tight performance
  Solder termination allows secure, low-resistance cable connections
  Operates across -25 °C to 85 °C for varied temperature environments

Applications

• Suitable for automation sensor cabling in harsh environments
  Ideal for electrical harnesses in machine control panels
  Used with instrumentation requiring sealed connections outdoors
  Can be used for small motors or actuators requiring low-voltage feed

What mounting method is used and how does it affect installation?

It uses a cable mount with a snap-in mating type, permitting direct in-line installation without additional panel cut-outs and enabling quick mating and demating during field service.

What protection does it offer against contaminants?

The connector meets IP67 ingress protection, providing dust exclusion and protection against temporary immersion in water, so it is suitable for wash-down or damp locations.

Which contact materials are specified and why are they chosen?

Contacts are bronze with a gold plating, chosen to combine mechanical strength with a low-resistance, corrosion-resistant contact surface suitable for repeated connections.

What electrical limits govern its use in circuitry?

It is rated for low-voltage applications up to 125V with a current capacity of 2.5 A per contact, aligning it with signalling and small-power distribution tasks.

Are there any recognised approvals for industrial deployment?

It carries UL approval, which confirms it meets specified safety standards for electrical components within applicable industrial applications.
