TMR-05

TMR-05 Self-Adhesive Flat TM Reader

Flat zinc-alloy reader that sticks on — designed for mounting without drilling.

Peel the backing, press it on, route the lead — installed. The TMR-05 is a low-profile zinc-alloy reader with a 3M VHB adhesive pad on the back, so it goes onto a finished surface with no drilling, no nut and no panel cut-out. At 9.87 mm deep and Ø37.02 mm across the flange it sits almost flush, and two Ø4.50 mm screw holes on a 28.80 mm pitch are there if you want a mechanical fixing as well — the wide flange can also cover an untidy existing cut-out, which makes it a candidate for retrofit on an old intercom panel. A green/red LED ring around the contact gives a two-colour answer at the point of touch, and the solid one-piece metal face is designed to resist prying, weather and wear on a street-facing door. Finish options (for example polished chrome, polished gold, satin stainless): availability, MOQ and cost are confirmed in the quote. Compatibility depends on your controller; test a sample on your own system before ordering.

Why this model

Two wires, one polarity flip — red or green from the same pair

The clever part is the wiring. Instead of three LED wires, the TMR-05 brings out a single pair: drive white positive and yellow negative and the ring lights red; reverse the pair and it lights green. One controller output with an H-bridge or a simple polarity-reversing relay can give you both colours, which can make this reader easier to retrofit onto systems with only one spare output (check against your own controller). Add the 3M VHB pad and the fact that nothing has to be drilled, and it becomes a reader to consider for a rented shopfront, a finished stone facade or a machine you are not allowed to modify; check adhesion on your own surface before ordering.

Key features

3M VHB self-adhesive pad on the back — peel, press and it is mounted; no drilling, no nut, no cut-out.
Solid zinc-alloy body with chrome-plated copper contact — a rugged interface for harsh environments.
Integrated green/red LED ring gives user-feedback signalling right at the contact.
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.
Four wires — red DATA, black GND, white and yellow to the LED; reversing that pair switches the ring between red and green.
LED rated 20 mA maximum, typically DC 12 V.

Frequently asked questions

Can the TMR-05 really be installed without drilling?

Yes — a 3M VHB adhesive pad on the back: peel, press onto the finished surface, route the lead. Two Ø4.50 mm screw holes at 28.80 mm pitch are there if you want a mechanical fixing too, and the wide Ø37 mm flange covers untidy old cut-outs on retrofit panels.

How does the two-wire LED switch between red and green?

By polarity: drive white positive / yellow negative and the ring lights red; reverse the pair and it lights green. One controller output with an H-bridge or a polarity-reversing relay gives both colours — ideal when only one spare output exists.

What finishes are available?

Finish options include polished chrome, polished gold, satin stainless and the crackle-silver TMR-05B (intended to be more scratch- and corrosion-resistant). Colour, marking and other customization options: feasibility, MOQ and cost are confirmed in the quote. The LED is rated 20 mA max, typically driven at DC 12 V.
