[Product Selection](https://637862.hs-sites.com/product-selection?hsLang=en-us) September 25, 2026 # Discontinued Products ### S2 Sensors Have Been Discontinued Unfortunately, due to the microprocessor used by our S2 Sensors becoming discontinued, we are no longer able to provide enDAQ's S2 Sensors. We apologize for any inconvenience this has created, and invite you to please reach out to our [Customer Success Team](https://endaq.com/pages/contact). They will put you in contact with one of our enDAQ engineers who will be able to provide you with alternate enDAQ sensor options to help you with your shock, vibration and environmental data acquisition and analysis. Contact: [Customer Success](https://endaq.com/pages/contact) ### Old Part Numbers Mapped to New Our old Slam Stick part numbers were long and confusing!  They have been replaced by part numbers that describe the product from the outside-in (as the customer sees it), not from the inside-out (as we had seen it).  Our product naming convention has also been dropped and replaced by more simple part numbers that will double as names, much in the same way as luxury car companies. The new part numbers and names coincide with an updated design of the products which include a better secondary accelerometer, more storage, and advanced firmware capabilities.  Some of these new products that aren't available yet are designated in italics. | **Old Number & Name** | **Primary Accelerometer** | **New Number & Name** | | --- | --- | --- | | W8-R2000D40 | [Piezoresistive](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series?_=pf&pf_t_primary_accel=Primary%20Accel.__Piezoresistive) | [W8-R500D40](https://endaq.com/collections/endaq-shock-recorders-vibration-data-logger-sensors/products/w8-shock-sensor-w8-r500d40), [S5-R2000D40](https://endaq.com/collections/endaq-shock-recorders-vibration-data-logger-sensors/products/s5-shock-sensor-s5-r2000d40) | | W8-E2000D40 | [Piezoelectric](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series?_=pf&pf_t_primary_accel=Primary%20Accel.__Piezoelectric&pf_t_enclosure_material=Enclosure%20Material__Aluminum) | [W8-R500D40](https://endaq.com/collections/endaq-shock-recorders-vibration-data-logger-sensors/products/w8-shock-sensor-w8-r500d40), [S5-R2000D40](https://endaq.com/collections/endaq-shock-recorders-vibration-data-logger-sensors/products/s5-shock-sensor-s5-e2000d40) | | Slam Stick C (LOG-0003) | [Digital Capacitive](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series?_=pf&pf_t_primary_accel=Primary%20Accel.__Digital%20Capacitive) | [S3-D16](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s3-vibration-sensor-s3-d16), [S3-D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s3-vibration-sensor-s3-d40), [S4-D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s4-vibration-sensor-s4-d40), [S5-D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s5-vibration-sensor-s5-d40) | | Slam Stick X Polycarbonate (LOG-0002-PC) | [Piezoelectric](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series?_=pf&pf_t_primary_accel=Primary%20Accel.__Piezoelectric&pf_t_enclosure_material=Enclosure%20Material__Polycarbonate) | [S3-E25D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s3-vibration-sensor-s3-e25d40), [S3-E100D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s3-shock-vibration-sensor-s3-e100d40), [S3-E2000D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s3-shock-sensor-s3-e2000d40) | | Slam Stick X Aluminum (LOG-0002-AL) | [Piezoelectric](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series?_=pf&pf_t_primary_accel=Primary%20Accel.__Piezoelectric&pf_t_enclosure_material=Enclosure%20Material__Aluminum) | [S4-E25D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s4-vibration-sensor-s4-e25d40), [S4-E100D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s4-shock-vibration-sensor-s4-e100d40), [S4-E2000D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s4-shock-sensor-s4-e2000d40), [S5-E25D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s5-vibration-sensor-s5-e25d40), [S5-E100D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s5-shock-vibration-sensor-s5-e100d40), [S5-E2000D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s5-shock-sensor-s5-e2000d40) | | Slam Stick S (LOG-0004) | [Piezoresistive](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series?_=pf&pf_t_primary_accel=Primary%20Accel.__Piezoresistive) | [S4-R500D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s4-shock-sensor-s4-r500d40), [S4-R2000D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s4-shock-sensor-s4-r2000d40), [S5-R500D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s5-shock-sensor-s5-r500d40), [S5-R2000D40](https://endaq.com/collections/endaq-sensors-shock-vibration-s-series/products/s5-shock-sensor-s5-r2000d40) |   -
