8K2 Safety Edge End Resistor for 45mm Resistive Edge

The end termination that makes a 45mm resistive safety edge read correctly on your control board. A resistive edge tells the control unit it is healthy by showing an 8.2 kilohm reading across the line, and this 8K2 resistor set closes the far end of the edge to give that value. It is a spare for a self-assembly 45mm edge, or the extra part you need when several edges are looped together and traced back to the board. Each edge run needs correct termination, because the board reads the end of the line. The set is pictured as a domed black end piece with its connector and plug parts. Order the number of resistors you need for your edge layout. The price shown is for one resistor set.

Why this part works

A monitored edge is only as good as its termination. The board does not just look for a closed contact, it looks for the 8K2 value. If the end of the edge is broken, cut or unterminated the reading changes and the board can react, which is the reason for using a resistive edge at all.

Quick to fit on site. The edge profile is designed for fast assembly with no glue, so the resistor goes into the end of the 45mm profile as part of the same job, and you can replace a damaged end without changing the whole edge.

Made for looped layouts. Where several edges are looped together you may need extra resistors and cable connectors to finish each run correctly, and this is the part that does that.

Where it is used

Resistive safety edges on sliding and swing gates, repairs after an edge has been damaged by vehicles or vandalism, and new layouts where a survey of the gate has shown more than one danger point. Fit edges where the survey shows a risk of trapping, then trace them back to the control board.

Specifications

Choosing the right part

Check two things before ordering: that your edge is a 45mm profile, and that your control board expects an 8K2 resistive input. A mechanical contact edge does not use this part, and a board set up for a different value will not read correctly. Our 2m self-assembly edge kit is the matching edge for new layouts. For multiple edges, count one termination per edge run and add cable connectors to link the runs.

Fitting and care

Isolate the gate before working on the edge. Follow the assembly order for your profile, fit the resistor at the far end of the run, close the end, and check the edge at the board. Then test the gate: pressing the edge must stop or reverse the gate as your control unit is set up to do. Commissioning and testing must be done by a competent person.

Check the edge at every service, because a damaged profile or a corroded end can change the reading. Replace a resistor if you open the edge for any reason and find water or damage inside.
