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 the large number of controllers that have no spare output to drive an indicator, or installations where nobody is going to look at a light anyway, this is the version that gets fitted in a minute and never raises a wiring question. 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.
Two wires is the feature, not a limitation
Most reader faults on site are wiring faults, 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.
