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.

Note
For retro-reflective sensors a suitable reflector is required.
For PL80A, PL30A & C110 reflectors see stock nos. 265-2776, 265-2760 & 265-2748 respectively.
W4 Series - Miniature
The W4-3 series of photoelectric sensors offer best-in-class performance in a miniature housing design. Using the latest ASIC these sensors provide reliable object detection of transparent and glossy objects like blisters, e-cards and aluminium cans. Optical axes on the flat side enable simple, space-saving integration in machine environments.
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.
LED indicators located or the top panel allows 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.
Features and Benefits
· Reliable object detection due to superior ASIC technology with high immunity to ambient light
· PinPoint technology provides a bright, small and precise light spot that enables quick and easy sensor alignment
· Highly visible 360° status LEDs provide quick and easy setup
· Compact and rugged housing design easily fits in tight spaces
· Flexible sensor settings, monitoring, advanced diagnostics, and display thanks to IO-Link
· Application versatility due to reliable detection of shiny or jet-black objects
· Rugged mounting system with M3 threaded metal inserts reduces maintenance costs due to a long service life
· High immunity to ambient light reduces downtime caused by false trips
· IO-Link provides easy data access from the PLC
· Quick and easy configuration
· Quick and easy integration using function blocks
