TMR-05A

TMR-05A Two-Wire Self-Adhesive TM Reader

The TMR-05 stripped to two wires — DATA and GND, nothing else to connect.

The same zinc-alloy body, the same 3M VHB adhesive back, the same 9.87 mm profile — without the LED. That leaves exactly two wires: red DATA and black GND. For controllers that have no spare output to drive an indicator, or installations where an indicator light is not needed, this is the two-wire version, designed for quick fitting with a simple connection. Peel, press, land two cores on the terminal block, done — no drilling, no nut, no cut-out, and no discussion about which colour means what. Compatibility depends on your controller; test a sample on your own system before ordering.

Why this model

Two wires is the feature, not a limitation

Wiring mistakes are a common cause of reader faults on site, and every extra core is another chance to make one. The TMR-05A removes the LED pair entirely: red to DATA, black to GND, and there is no third possibility to get wrong. That matters when the installer is on a ladder, when the controller genuinely has no spare output, or when the reader goes somewhere nobody will ever glance at an indicator — a gate post, a plant-room door, an unattended cabinet. Everything else is identical to the TMR-05: same zinc-alloy face, same 3M VHB pad, same 9.87 mm depth, same optional screw holes. If you do want visual feedback, order the TMR-05 instead; the panel cut-out and mounting are unchanged, so you can mix both across one site.

Key features

Two-line design — red DATA and black GND, the simplest wiring in the reader range.
3M VHB self-adhesive pad on the back — peel, press and it is mounted; no drilling needed.
Solid zinc-alloy body with chrome-plated copper contact; self-aligning face guides the key.
Only 9.87 mm deep, Ø37.02 mm flange, Ø16.70 mm contact ring; two Ø4.50 mm screw holes at 28.80 mm pitch for optional fixing.
Same body and mounting as the TMR-05 — mix LED and non-LED units across one site without changing the fixing.

Frequently asked questions

How is the TMR-05A different from the TMR-05?

Same die-cast zinc body, same 3M VHB adhesive back, same 9.87 mm profile — minus the LED. That leaves exactly two wires, red DATA and black GND, and nothing else to connect.

When is the two-wire version the right choice?

When the controller has no spare output to drive an indicator, or nobody will look at a light anyway — it is quick to install, with only two wires to connect.

Does it keep the no-drill mounting?

Yes — peel the VHB backing, press on, land two cores on the terminal block. Optional screw fixing via two Ø4.50 mm holes at 28.80 mm pitch if you want mechanical backup.
