Product Change Notification for Littelfuse Overmolded Reed Switches: 59045, 59050 series

To whom it may concern,

Littelfuse would like to notify you of a change related to our overmolded reed switch series 59045 and 59050.

• The marking on the products will change from “HAMLIN” to “LITTELFUSE”, due to the acquisition of Hamlin

by Littelfuse.

• There will be no change of fit, function, quality & reliability, this is a marking change only.

• The changes will affect products with a date code from week 45/2022.

• Since this is a running change, and there is still some inventory with the previous marking, the following

might occur:

o Mix of HAMLIN / LITTELFUSE marking within one box

o Mix of HAMLIN / LITTELFUSE marking within one carton

o Mix of HAMLIN / LITTELFUSE marking within one shipment

Please note this change impacts the attached list of products only.

If you have any additional questions or concerns, please contact me or your Regional Sales Manager.

Best Regards,
