New H4PD1-22, Dual Axis, MEMS, PWM

Product Announcement from Rieker, Inc.

The H4PD sensor provides dual axis inclination sensing in a rugged environmentally protected housing. This unit incorporates a MEMS (Micro-Electro-Mechanical Systems) sensing element referenced to gravity with integrated temperature compensation over the industrial operating range of -40º to +85ºC. The PWM (Pulse Width Modulated) output is linear with respect to the input angle directly.

Small dimensions and common footprint make it easy for field replacement.

The housing footprint is designed for retrofitting in the field without re-drilling mounting holes (common placement of center and slider flanges).
