What individual class members receive in a class action settlement depends entirely on the terms of that settlement. Often the settlement terms provide from a coupon, gift certificate or other form of payment other than cash.
You should review the notices you received regarding the class action to figure out what you can receive and what steps you need to take in order to collect.

You may be able to find the terms of the class settlement from that case to determine what benefits the class members receive. The benefits to the class are not always in cash, coupons, or discounts. Sometimes it is the benefit of the company following the law in future transactions and correcting past practices, also known as an injunction or declaratory relief.
If the settlement provides for cash benefits to be paid to each member of the class, perhaps they did not have your correct mailing address or there was a requirement that you submit a proof of claim to receive such benefits by a certain date.
In civil court proceedings, the word "always" never applies.
It is unusual that there would be a class action based on the facts you indicated. It may well be that any relief afforded victims of illegal strip searches was not monetary. You will need to review the terms of the settlement agreement or the notices sent to class members to determine whether any payment of cash was available.
