MODEL 805M1 ACCELEROMETER SPECIFICATIONS  TO-5 Series Accelerometer  3-Wire Voltage Output  Low-Cost, Embedded Applications  <0.80mA Power Consumption The Model 805M1 is a miniature adhesive mount voltage output accelerometer built on a 3-pin TO- 5 header. It is available in ±20g to ±500g dynamic ranges and offers a flat frequency response to 12kHz. The accelerometer features a hermetic construction in a TO-5 header configuration. The model 805M1 incorporates a stable piezo-ceramic crystal with low power electronics in a 100% shielded housing suitable for many embedded OEM applications. The model 805M1 accelerometer is offered in two configurations; one for adhesive mounting and one for stud mounting. An isolating cover option is also included for the standard model. FEATURES  ±20g to ±500g Range  Wide bandwidth up to 12kHz  TO-5 Configuration  Hermetically Sealed  -40°C to +100°C Operating Range  Case Grounded Design  3.0-5.5 Excitation Voltage APPLICATIONS  Machine Monitoring  Embedded Preventive Maintenance  Low-Cost OEM Installation  Permanent Structural Study  Embedded Sensing Solution SENSOR SOLUTIONS /// Model 805M1 Rev E 12/2017 Page 1 MODEL 805M1 ACCELEROMETER PERFORMANCE SPECIFICATIONS All values are typical at +24°C, 80Hz and 5Vdc excitation unless otherwise stated.
