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
LKM445/446 Indoor Temperature & Humidity Sensor
The LKM 445 / 446 is a low cost internal temperature and humidity sensor which has an integrated measuring transducer and two voltage outputs. The sensor allows the user to measure the temperature and moisture levels in buildings, plants and switch cabinets. This temperature sensor can be connected directly to an evaluation unit that also has voltage inputs such as PC cards or PLCs plus is supplied fully calibrated. The LKM 445 / 446 sensors have an accuracy of + / 0.5 °C plus a relative humidity of 3%. two controllers are supplied enabling users to carry out minor corrections on site. The sensor is also only suitable for use within enclosed spaces and when mounting the sensor special attention should be paid to positioning the sensor. There is a cable outlet at the back of the sensor and a lateral cable outlet is an available option. This temperature / humidity sensor has a protection class and users have the option to switch to a temperature range of -20 to 80°C.
