TMR-02-4P

TMR-02-4P Panel Probe with LED (DS9092L format)

The TMR-02 with a built-in LED — four wires, so the controller can light the ring on a valid read.

Same solid-metal panel probe as the TMR-02, with an indicator LED built into the contact ring and a four-wire tail to drive it. The user gets an unambiguous "accepted" signal at the moment of touch instead of guessing from a distant beeper or a lock that may or may not have released — which can reduce repeated re-presenting of keys at a busy entrance. The sliding contact face is designed to wipe itself clean with each use, the body takes panels up to 3 mm through an M18×1 nut, and the 205 mm colour-coded leads (black GND, red DATA, yellow and orange LED) come pre-wired so the installer only strips and terminates.

Why this model

Feedback at the point of contact

The LED is not decoration — it is there to shorten the queue. On a plain probe the user learns whether the read worked only from something else: a beeper inside the lobby, a lock click they cannot hear over traffic, a door that stays shut for another half second. So they may present the key again, and again. Putting the indicator in the ring they are already looking at closes that loop right at the contact. Two of the four wires are the LED pair, so the controller decides what the signal means — steady for armed, flash for denied, whatever your firmware already does. Where the panel is metal, consider the TMR-04A instead: its ABS capsule isolates ground and it carries a green/red LED.

Key features

Integrated LED in the contact ring gives the user an unmistakable read confirmation at the point of touch.
Uses an M18×1 panel cut-out like the DS9092L series; verify thread, panel thickness and wiring against the drawing before ordering.
LED rated 20 mA maximum, typically DC 2.7 V; driven by the controller through the two LED wires.
Sliding contact surface is self-cleaning; solid metal body suits panels up to 3 mm thick.
205 mm colour-coded four-wire tail: black GND, red DATA, yellow LED+, orange LED− — polarity marked, no guesswork on site.

Frequently asked questions

Is the TMR-02-4P compatible with the Dallas DS9092L?

It is offered as a DS9092L-style probe with an indicator LED. Confirm dimensions and wiring from the supplied documentation. Support for a particular TM1990A or RW1990 version also depends on the controller and firmware; verify the complete assembly with samples before replacement.

How do I drive the built-in LED?

Through the four-wire tail (black GND, red DATA, yellow LED+, orange LED−): the LED is rated 20 mA max at typically DC 2.7 V — drive it from a controller output with a series resistor.

What panel thickness does it take?

Panels up to 3 mm through the M18×1 nut, with a 205 mm tail. The TMR-02-4P-A variant ships with a 4P-2.54 connector instead of bare leads. LED colour, cable length, terminal and other customization options: feasibility, MOQ and cost are confirmed in the quote.
