1889259

What type of component is this?

This is a single-position PCB terminal block designed to connect field wiring to a printed circuit board using a spring-cage connection.

What are the nominal electrical ratings?

The terminal block has a nominal current rating of 16 A and a nominal voltage rating of 400 V. Its rated voltage varies by overvoltage category and pollution degree, reaching up to 630 V under category II/2 conditions.

What conductor sizes can be connected?

Phoenix Contact 1889259 accepts solid conductors from 0.2 to 2.5 mm² and flexible conductors from 0.2 to 1.5 mm². The corresponding range is AWG 24 to AWG 14.

Can conductors fitted with ferrules be used?

Yes. Flexible conductors fitted with ferrules, with or without plastic sleeves, can be used in sizes from 0.25 to 1.5 mm².

How much insulation should be stripped from the conductor?

The specified stripping length is 7 mm. Following this dimension helps the conductor sit correctly within the spring-cage terminal.

How is the terminal mounted to a PCB?

The component is intended for wave soldering. It uses two 0.7 x 0.7 mm solder pins, each 3.5 mm long, with a PCB hole diameter of 1.1 mm and pin spacing of 5.08 mm.

What is the conductor entry angle?

The conductor-to-PCB connection direction is angled at 45 degrees. This configuration can improve wiring access and support multi-row PCB layouts.

What are the component's dimensions?

The terminal block measures approximately 14.1 mm long, 5 mm wide, and 16.25 mm high. Its height excluding the solder pins is approximately 12.75 mm.

Can multiple modules be combined?

Yes. The side-latching design allows individual modules to be grouped to create terminal blocks with different numbers of positions. An appropriate end terminal block is required to complete a custom group.

Which end terminal block is used with a custom group?

The specified end terminal block is ZFKDSA 1,5C-6,0, order number 1889262. It is used to terminate an assembled group of individual modules.

What material is used for the housing?

The green housing is made from polyamide insulating material. It has a UL 94 V-0 flammability classification.

What material and finish are used for the contacts?

The contacts are made from a copper alloy and have a hot-dip tin-plated surface. The terminal and soldering areas use a tin top layer.

What tool is suitable for opening the spring-cage connection?

A fixed flat-blade screwdriver can be used to open the clamping space during conductor insertion. The specified accessory is the SZF 1-0,6X3,5 actuation tool, order number 1204517.

What approvals does this terminal block carry?

The documented approvals include EAC and cULus Recognized. Electrical ratings under these approvals may differ from the general IEC-based nominal ratings, so the applicable panel and equipment requirements should be checked.

What is the rated surge voltage?

The terminal block has a rated surge voltage of 4 kV across the documented overvoltage category and pollution degree combinations.

What applications is this component commonly suited to?

It is suited to PCB-based power and control connections in industrial electronic equipment, including control panels, power supplies, interface boards, instrumentation, and automation assemblies requiring compact spring-cage wiring.
