Does your bike trip stop light sensors?

I've found that I have to be directly over the longitudinal wire shown in the illustrations that HardyWeinberg stole from here. If you can ride the entire length of the wire...especially the center wire of a dipole loop...it helps trip the signal. Stop with your wheel directly over the wire as well.
We have a local median stirp MUP that I find very annoying. It does have button triggers that one can hit if one stops. But, It doesn't trigger the walk sign without hitting the button which is awkward to get to, and may loose a full light cycle.
I've determined that if there is a green light for cars in both directions on both sides of me, then there is no cross traffic and I just go.

The town just south of us is replacing their inductive loop detectors with microwave sensors that sit on the traffic or light poles at an intersection. Not only does the new system reliably detect bicycles, but it distinguishes them from other traffic and is connected to the traffic light controller to extend the time for a yellow light if a cyclist is in the intersection so he'll have time to clear the cross road before traffic there gets a green.

Until I read that link or a similar one several years ago I could never get a light to trip. Since then, I seldom have a problem.

Some of the sensors work around here, others don't. Apparently they can be adjusted for sensitivity but it's not always done properly. I have complained to the city about sensors that don't work but nothing is ever done about it. So, I have a couple of lights on my commute route that I run, after coming to complete stop and making sure the coast is clear. These lights will not change unless a car or truck trips the sensor; they will not trip for bikes no matter how long you wait.

Around here, the city does streetlights, but not traffic lights. Traffic lights in an olive green housing are maintained by the county. Traffic lights in a yellow housing are maintained by the state. The county does a good job of passing things up the line to the state. The city, not so much.
Remember that I work for local government, so I know how the sausage is made.

my dry season commuter is carbon with carbon wheels and is never detected by loop detectors without dismounting and dragging the chain rings across the edge of the loop. this gives me a terrific excuse to do what i always do...blow magic glowing traffic orbs. and if i make you look bad...well tough :NC17:ing cookies.

My local bike laws have within them an exception to red lights if your bike does not trip the sensor and you have to wait "an unreasonable amount of time" for the light to turn. That is obviously open to interpretation, but I would like to think that it wouldn't take too much to explain to a judge, or even the citing officer, of why you felt it prudent to run a red.

the 5 way intersection I just push the Pedestrian Crossing Button , or having been here over 15 years I know the sequence and timing of that intersection.

I don't have an issue with using the beg button, I often do. But when making a left turn, there's no beg button without crossing two (or more lanes of traffic). I actually did this earlier this week, in the left turn lane, car behind me was too nice leaving too much room and wasn't close enough to trip the sensor. I dismounted, crossed to the beg button to get the light to change.
Likewise, I have no issue waiting for an opening and crossing against the light - I do this just as often as hitting the beg button. This is legal in Minnesota for bikes and motorcycles, but not legal in all states.
