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.

Photoelectric Proximity Sensors - W12 Series
SICK W12-3 photoelectric sensors are enclosed in a rugged metal housing for demanding applications. Distinguished by the ability to offer reliable detection over long sensing distances. The sensors are compatible for various operations, with the in-built SICK ASIC technology. The W12-3 photoelectric sensors offer many advantages over conventional optical sensors due to superior OES technology. With a wide selection of variants, simple mounting and excellent detection reliability, even under difficult conditions.
PinPoint LEDs detect all kinds of objects including transparent objects, light & dark, large or small and even people. The PinPoint technology enables quick and easy sensor alignment and provides a precise, highly visible light spot that is unaffected by peripheral light.
The W12-3 heavy duty photoelectric sensors are designed to enable intuitive set-up. Teach buttons and LED indicators located or the rear panel allow the operator to quickly and easily set the minimum and maximum distances. In addition, the IO-Link function offers full process control, from commissioning to service.
