Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
RS Pro Type J and K IEC Thermocouples with Adjustable Bayonet Probe
From RS Pro a range of Type J and Type K thermocouple temperature sensors that conform to IEC 60584 standards with a grounded hot junction for a fast resposne time. These durable type J and Type K thermocouples have a 2 m long wire with glass fibre insulation and a stainless steel braid. The probe is fitted with an adjustable spring loaded bayonet probe to enable it to be fitted securely.
How does a Thermocouple Work?
A thermocouple is a sensor used to measure temperature in a range of different processes and consists of two wire legs made from different metals joined together at their two ends to form two junctions. The hot, or measuring junction is connected to the body whose temperature is going to be measured. The cold junction or reference junction is connected to a body of known temperature. When the measuring junction is placed on something hot a voltage or potential difference between this and the reference junction occurs. This voltage can then be converted into a temperature measurement using thermocouple reference tables. This process is also known as the Seebeck Effect
What is a Welded Grounded Junction?
In a welded grounded junction the two thermocouple wires and sheath are welded together to form one junction at the probe tip. These thermocouples have a fast response time because all the thermocouple is making contact with the sheath allowing the heat to transfer easily.
What is an Adjustable Bayonet Probe
The probes of these thermocouple sensors have an adjustable screw threaded spring 175 mm long with a slotted bayonet fixing cap. The bayonet cap screws along this spring and allows the immersion length of the thermocouple probe to be adjusted. Once in place the bayonet cap is secured to a bayonet adapter (which must be purchased separately - see stock number 621-2243) allowing the thermocouple to be firmly held in place within the recess. The advantages of this method of fixing are;
• Immersion depth can be adjusted easily
• Secure connection within machine recess
• Positive pressure at the thermocouple tip and full immersion in process
Features and Benefits
• Adjustable bayonet probe
• Grounded hot junction
• Fast response time
• Rugged glass fibre insulated wire with stainless steel overbraid
Applications
These Type J and Type K adjustable bayonet probe thermocouples are designed for direct installation into the process. The bayonet fitting makes them suited for applications where the thermocouple sensor tip is fitted directly into a drilled hole or recess in machinery. Typical applications include the plastics and rubber industry where they are used in extrusion and moulding machinery
