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
Phoenix Contact Non-Latching Relays - RIF2 Power Relay Module Series
Phoenix contacts series of RIF2 power relay modules come pre-assembled with a push connection. They are considered to be electrical and mechanical devices. This type of relay can often be referred to as an electromechanical relay or an industrial switch. This RIF2 professional range is supplied with a base suppressor and retaining bracket that benefits from a universal plug-in design.
Features & Benefits
• Robust and hard-wearing
• Easy wiring because of the advanced push-in connection technology
• Easy handling and extension of range
• Includes a plug-in display/suppressor module
• AC and DC versions available
• 2 or/and 4 contact options
• Yellow LED indicator
• Varistor or damping diode protective circuit
• The relay retaining bracket that is included is complete with ejector function and holder for marking material
What is a non-latching relay and how do they work?
A relay is an electrical switch that is operated by electrical pulses, their primary function is to open and close a circuit. When power passes through a circuit, a relay switches position (usually from NC to NO) using an internal coil which generates a magnetic force. This force then holds the relay in a NO position, when the current is switched off the relay returns to the NC position. This function is what makes these non-latching relays perfect for push-button applications such as keyboards and micro-controller input buttons.
A little more info
Non-latching relays support a range of signal characteristics, ranging from low voltage or current to high voltage or current and from DC to GHz frequencies.
What is the difference between a latching relay and a non-latching relay?
When a latching relay operates its contacts, the relay holds its position, even when the supply of its operating coil has been disconnected. When a non-latching relay operates its contacts, the relay will reset automatically once the supply of its coil is disconnected through the internal spring mechanism.
