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.

PR Electronics - Ex Interfaces
PR Electronics 5202B Ex Pulse Isolator
PR Electronics 5202B pulse isolator for transmission of signals to the safe area from NAMUR sensors installed in hazardous areas. This signal conditioning isolator measures one or more pulse inputs and provides an identical number of isolated pulse outputs. The PR 5202B uses transformer and optical isolation techniques to provide 3.75 kVac galvanic isolation between the input, output and power terminals. The high level of electrical isolation means that input pulses sensed at the 5202B are not electrically connected to the output pulse. The 5202B has been designed, developed and certified for use in SIL 2 applications according to the requirements of IEC 61508.
Besides providing isolation, the PR 5202B is a barrier. This means that the module can make an intrinsically safe measurement of contacts and NAMUR sensors mounted in a zone 0/ Division 1 explosion hazard area. The PR 5202B limits the level of energy present at the contact or the NAMUR sensor to a low intrinsically safe level, thereby preventing ignition of a flammable atmosphere around the sensor – even if the sensor or the cable is damaged.
Features and Benefits
• 3.75 kVac galvanic isolation between input, output and supply
• One input signal can be used on two separate outputs
• A cable error alarm can be detected on a separate output
• Designed, developed and certified for use in SIL 2 applications
• Front LED indicates operation status and malfunction
• DIN rail mounting
