The S4-E500D40 is a shock recorder with a high performance piezoelectric accelerometer, a secondary capacitive accelerometer and other environmental sensors. This model is most popular for shock testing. Its aluminum enclosure improves reliability in harsh environments and widens its frequency response.

Complimentary enDAQ Pelican case included with every enDAQ® sensor order.

Accelerometer Specifications>> More Information

Accelerometer Type	Range	Sampling Rate	Bandwidth	Noise	Resolution
Piezoelectric	± 500g	20,000 Hz	5 to 2,000 Hz	< 0.2 gRMS	0.015 g
Digital Capacitive	± 40g	4,000 Hz	0 to 300 Hz	< 0.01 gRMS	0.00008 g

Please note: Piezoelectric accelerometers are susceptible to saturation due to exposure to high frequency events because they are AC coupled. If your application will have high frequency events (events with pulse widths less than 1 ms) we recommend checking out our S-R series products.

Battery & Storage Performance >> Battery Specifications >> Battery Life Estimator

Battery performance is heavily dependent upon the device configuration (sensor sample rates and triggers), battery age (including charging cycles), and temperature. The following table provides the battery life and storage capacity of this device assuming it has a relatively new battery and it is at room temperature. When showing performance it assumes all sensors are on at the default sample rate with the main accelerometer sample rate driving performance. With triggers, it assumes the device is in trigger mode 99% of the time. Here are some additional resources: Measurement Settings, Battery Specifications, Battery Life Estimator Tool.

Sample Rate	Storage Capacity	Continuous Recording	Main Accel. Trigger	2nd Accel. Trigger	Periodic/Time Trigger
100 Hz	22 days	13 hours	13 hours	52 hours	52 days
1,000 Hz	9 days	12 hours	13 hours	52 hours	49 days
