Why Choose the TE Connectivity 1SNA199528R2100 DS2.5/8.P.ADO Ground Terminal Block?

The TE Connectivity 1SNA199528R2100 is a green-yellow DS2.5/8.P.ADO ground terminal block designed for protective earth connections in compact industrial control and automation systems. Part of the established TE Connectivity ENTRELEC SNA ADO series, it combines ADO insulation displacement connection technology with a screwless rail contact for dependable protective conductor termination.

The DS2.5/8.P.ADO is specifically designed for installations where available panel space is restricted. Its 8 mm spacing, 2.5 mm² rated cross-section and ADO-to-ADO connection arrangement provide an efficient solution for protective earth wiring, while the green-yellow housing gives clear visual identification of the ground connection.

Designed for mounting on TH35-7.5 and TH35-15 DIN rails, the terminal uses a screwless rail contact that provides secure electrical connection to the mounting rail without operator-dependent tightening. It accepts 1–2.5 mm² conductors, supports up to two wires per connection and is particularly suited to industrial installations exposed to vibration, shock and other demanding operating conditions.

Key Advantages

  • Dedicated protective earth ground terminal block for industrial electrical systems.
  • Screwless rail contact provides a secure protective connection without operator-dependent tightening.
  • ADO insulation displacement connection technology supports fast and reliable conductor termination.
  • Accepts 1–2.5 mm² conductors with up to two wires per connection.
  • Compact 8 mm spacing helps maximise available DIN rail space.
  • Green-yellow housing provides immediate identification of the protective earth connection.

Key Features

  • TE Connectivity ENTRELEC SNA ADO series.
  • DS2.5/8.P.ADO ground IDC terminal block.
  • ADO System connection technology on both sides.
  • 2.5 mm² rated cross-section.
  • 1–2.5 mm² conductor range.
  • Equivalent conductor range of 16–14 AWG.
  • Supports up to two wires per connection.
  • Screwless protective earth rail contact.
  • Green-yellow housing for protective conductor identification.
  • Compatible with TH35-7.5 and TH35-15 DIN rails.

Secure Protective Earth Connections with ADO Technology

Protective earth terminal blocks provide a direct electrical connection between protective conductors and the mounting rail. The TE Connectivity DS2.5/8.P.ADO incorporates a screwless rail contact, helping protect the installation in the event of a fault while eliminating dependence on manually tightened rail-contact screws.

The ENTRELEC ADO System uses insulation displacement connection technology for efficient conductor termination and is designed for demanding control applications exposed to vibration, shock and corrosion. Combined with secure TH35 rail mounting, a compact 8 mm profile and support for 1–2.5 mm² conductors, the 1SNA199528R2100 provides a practical protective earth solution for industrial control equipment.

Typical Applications

  • Protective earth connections in industrial control panels.
  • Machine building and factory automation systems.
  • Electrical cabinets and distribution assemblies.
  • Instrumentation and process control equipment.
  • Industrial systems exposed to vibration and shock.
  • OEM machinery requiring compact DIN rail grounding connections.
