Specifications subject to change without notice |

| (1) Random
force ratings assume a flat PSD profile: 20-2 kHz bandwidth, 3 sigma
response and the following pure mass payloads: 200 lbs for C40HP; 310 lbs
for C90HP; 450 lbs for C150HP.
Consult MB if your conditions are
markedly different. (2) Shock force ratings assume 30 g/11 msec half-sine pulse. Consult MB for other shock tests. (3) Several suppliers quote systems with uncommonly small amplifiers having large force ratings but they are severely limited by very small velocities (sometimes less than half of MB's velocity rating!). (4) C40HP and C90HP recenter payloads up to 800 pounds vertically. Larger payloads need auxiliary support for vertical tests. (5) C150HP recenters payloads up to 1500 pounds vertically. Larger payloads need auxiliary support for vertical tests. (6) Random vibration levels above 35 gRMS may require special options (depending on test). Consult MB about high level tests. (7) Each sinusoidal test is limited by velocity and displacement specified for a given shaker system. *Payloads shown include all mass attached to the shaker's moving element including Unit Under Test (UUT), hold-down fixturing, slip plate (if any), head expander (if any), attachment bolts, etc. |

MB's line of PM-SERIES Shakers uses permanent magnet
technology and the voice coil principle to create vibration. These
multi-purpose shakers are heavy duty, rugged, industrial quality equipment
with a proven track record of lasting decades in
demanding applications. You can buy "bargain basement"
shakers or you can choose MB PM-Shakers which will provide years of
dependable, reliable, consistent testing. Choose from five different sizes
with maximum sine force ratings of 25, 50, 100, 250 or 500 pounds. The
PM25A, PM50A, and PM100A shakers all have 1/2" stroke and a 2.7" diameter
mounting table. The PM250HP and PM500HP shakers each have 2" of stroke and a
4.1" diameter mounting table.

The C40HP, C90HP, and C150HP Electrodynamic
(E-D) Shakers from MB reflect the latest in enhanced design and increased
performance. A well-respected brand since the 1950s, MB shakers have earned
a reputation for high performance, longevity, reliability, and
dependability. These three enhanced HP models build upon MB's family of
C-Series Shakers (C10, C25, C40, C50, C60, C90, C125, C126, C150, C200,
C210, C220), a family with a strong record of proven performance and
outstanding reliability for almost fifty years.
