Uchiya UP62G110
Thermal Switches/Sensors
110 °C, 230 °F, Normally Closed
Protectors/Thermostats
(Quantity 1)
The
UP62G110
is a 110 °C
Normally Closed
Thermal Switch. It stays
Closed
as the temperature rises to and passes the boiling point of water,
100 °C (212 °F)
, and stays closed until the temperature climbs upward to
110 °C (230 °F)
, at which time it opens. Whenever the temperature drops back below 110 °C, it closes again.
Please note that these devices continue to operate both above and below their operating temperatures — i.e., they are self-resettable. This is unlike the way thermal fuses work. Thermal fuses must be replaced after they trip. Instead, these devices continue to open and close as the temperature rises above and below their set point of 110 °C.
Also, please note that I also sell on Ebay the OP62G100 devices; The OP62G100 works oppositely to the UP62G110: The
OP62G100
is Normally Open; it closes at
100 °C (212°F)
and above.

Note:
This is one of the more difficult descriptions I have ever had to create. It is the first time I've ever found it necessary to use more than one of the manufacturer's data sheets. In fact, in this case I've had to use three of them (see below). And that's a shame, because these really are wonderful, well-built, low-cost, useful devices that deserve way better treatment than their literature provides.
There are several reasons why I say this. For one thing, I believe the Uchiya data sheets for the UP6G/OP6G devices provide conflicting and confusing information. And I think the biggest reason for this is Uchiya, like many oriental companies, may be reluctant to produce the English versions of their product information with input from those of us who actually speak the language. I don't know whether they do this to save money or whether they think that those within their company who are even vaguely familiar with the English language (i.e., a couple of years of instruction) can do it just as well as an English speaking person.
To show that I'm not just blowing wind about this, here are just a few of the deficiencies of their data sheets:
1) They group, as near as I can tell, around 5 different products, with around 17 different temperature ratings onto each of the three different data sheets, when it would have been just as easy
―
and far less confusing
―
to produce a separate data sheet for each one.
2) The information often conflicts from one data sheet to another.
3) The data sheets are laced with grammar mistakes.
4) The data sheets for these devices don't adequately differentiate between the OP6/UP6 and the OP6G/UP6G products, when clearly they are designed with different styles of application in mind.
5) They talk about things like the "G" models' "Platinum Gold Silver cross-bar contacts" without ever really describing the significance of the basic difference between these two lines.
6) They tell us about a "Differential" specification (30 +- 15k) without ever giving its units or any mention of what it is; and they never mention the products' hysteresis, which almost every thermal sensor would almost certainly have ― could it be that they are using the terms "Differential" and "Hysteresis" as one and the same?
7) They can't even decide what to call these devices
― "
Thermostats", "Protectors", "Thermal Protectors", "Switches," "Thermal Cut-Outs", "Cutoffs", "Thermal Sensors". (By the way, I like to call them "Thermal Switches", because that's what they are.)
8) The UP62G110 devices are normally closed whenever the temperature is below 110 °C At temperatures of 110°C or more, they open. It's that simple. Uchiya cloaks that simplicity in such language such as "Under abnormal conditions, the bimetal chip senses abnormal heating-up and minimum signal current (DC 1.5v, 1ma) flows to the circuit."
But where they really go south is when they try to list the applications for these devices. They shortchange their own devices by giving them a short list with applications such as "Inverter Ballast", "Motor Control Inverter", Solenoids", "Delay Timers", and "Ventilating Fans". Could this list be more shortsighted? It's pretty bad when the most creative application on your list is "Ventilating Fans". (Though I think it's the best app on Uchiya's list. Interestingly, it's the only one that uses the UP62G in what the data sheets call the "convection mode"
― which means it senses the heat of the surrounding air rather than bolting or clipping the device to the item being monitored ― a motor's housing, for example.)
The "G" in UP62G110
It's important to note that the "G" in the part number indicates that the UP62G parts are low power (1/2 amp maximum) devices that would only directly power such things as a fan or a relay. They not designed to directly control electronic equipment such as motors, heaters, etc. Instead, the real value of these parts is that they are to be used as sensor inputs to electronic control circuits, and especially for things like PLC (Programmable Logic Controller) inputs. In this light, since these circuits and PLCs are used throughout industry, the UP62G/OP62G parts are universally useful.
Here's what these things are really good for.
Okay, above I said there are lots of real good applications for the UP6G/OP6G devices. Here's my take on their very best application. But first, this caveat: They're cheap, rugged, easy-to-use, and they'll operate up to 10,000 times without failing. So any application where you need to monitor a temperature level is a good place for their application.
Currently, I'm only selling the UP62G110 (110 °C) and OP62G100 (100 °C); but keep in mind that Uchiya makes them, in 5
° increments,
in values from 55 °C to 140 °C in both the normally closed (UP) and normally open (OP) type. That's 18 of each, 36 devices total in just the 'G' or low-current versions.
This means that you can select almost any temperature level that's pertinent to your need. Then you connect it to an input to your circuit, or in many industrial manufacturing plants, your PLC (Programmable Controller). You can monitor whether any motor, any cabinet, any safety issue you can think of is within its boundaries.
But that's not all. Most manufacturing processes involve heating in their process in some way, often more than one. Using these devices is a good way to keep track of the fact that your heating mechanisms are within the temperature range that your process calls for.
So I'm touting this as one of the best applications for these devices ― because it has the possibility to solve a multitude of uses ― as many as your creative imagination can envision.
