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
Panasonic S Series Latching Relays
A latching relay is similar in design and function to a standard general-purpose relay. However, there is one main difference with a latching relay, in that the latching relay will remain in the last position of which it was powered. A non-latching relay will revert to its normal position.
APPROVALS : UL and CSA
From Panasonic, the S Series of high sensitivity, latching relays are designed for PCB mounting. Extremely reliable and efficient the S series range of PCB mount relays is resistant to vibration and shock, making them ideal for a wide range of industrial switch applications. Compact, with a low profile the S series of power relays, are typically used in designs and applications where PCB space saving is a priority.
Manufactured from high-quality materials the Panasonic S Series of latching relays have a long life and can be relied upon for all your design maintenance and repair needs.
