RoHS compliancy

The majority of the standard products available in the ELESA catalogue are compliant with the European Directive 2002/95/CE (RoHS directive, Restriction on Hazardous Substances).

However, there are some exceptions for some products which are not yet compliant owing to technological limits in the field of research in raw materials hence not due to ELESA's direct responsibility.By clicking on each product code in the table, you can directly check the status of the product as to RoHS compliancy.

All compliant products are supplied with a label showing the RoHS symbol.

Key (to be ordered separately)
High-resilience polyamide based (PA) technopolymer, colour black, matte finish. Zinc-plated steel bore. Resistant to solvents, oils, greases and other chemical agents.
- Code GN.39901, description GN 816-10 for all versions.

Accessories on request
GN 609 black-oxide steel distance bushings for assembling the plunger on thin sheets.

Features and applications
GN 816 spring plungers are protruding in the rest position. By pulling the plunger inside the body and turning the knob by 90°, the plunger reaches the retracted safety position by means of the pin sliding inside a slit. The plunger returns into the original protruding position by pulling once again the knob, making it turn by 90° and releasing it.
For GN 816-B and GN 816-BK the above operations may be carried out only by means of a key (to be ordered separately).
Supplied with the technopolymer sleeve not assembled. It can be assembled eventually by a simple pressure.
