TMR-02-4P Panel Probe with LED (DS9092L compatible)
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 is what removes the repeated re-presenting of keys at a busy entrance. The sliding contact face wipes itself clean on every 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.
Feedback at the point of contact
The LED is not decoration — it is what stops 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 present the key again, and again. Putting the indicator in the ring they are already looking at closes that loop instantly. 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, use 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.
- Compatible with the DS9092L series — drops into the same M18×1 panel cut-out.
- 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.
