APM HEXSEAL was founded in 1947 with the mission to devel-
op and manufacture environmental sealing solutions to pro-
tect and prolong the life of electromechanical switches and
circuit breakers in hostile environmental conditions around
the globe. This focused effort resulted in the development of
an extensive line of standard silicone sealing boots that are
compatible with the vast majority of switches, breakers, en-
coders, potentiometers and rotary devices used throughout
the world today.
Complimentary sealing products were soon
developed and patented, including a com-
plete line of reusable, self-sealing fasteners,
and silicone colorizing incandescent lamp fil-
ters that transmit colors for instrument panels
and lighted pushbutton switches.

APM Hexseal Boots for Toggle, Pushbutton
& Rotary Switches
Any unsealed electrical devices mounted to a control panel or piece of electrical equipment can
fall victim to the impacts of hostile environmental factors if not properly protected. In this
context, “environmental” is a very broad term, encompassing any number of possible factors,
including weather conditions like rain, snow or prolonged wind and sun exposure, pressure
changes from submersion in fluids or changes in altitude, contaminants such as water, ice, salt,
air, dust, dirt, grease, chemicals, and even spilled beverages.
APM Hexseal's Sealing Boots are designed to protect the vulnerable areas of a device, and
create a seal against the mounting panel, providing strong protection for the device itself, and
for the overall function of the system.

APM Hexseal Bushing Seals
For Switch Panel Cut-Outs
Bushing Seals pack all the sealing power of a boot, but
focus on the mounting hole as opposed to the switch itself.
Installed before a switch locking nut, the bushing seal fits
snugly against the mounting panel, sealing the mounting
hole from any possible intrusion. Bushing Seals are small,
inconspicuous and perfect for already sealed toggle, push
button and rotary switches.

APM Hexseal Boots for Circuit Breakers & Rocker Switches
Circuit breakers perform a very valuable role in all sorts of control systems, protecting equipment from short circuits and electrical overloads. APM Hexseal’s lever-
actuated circuit breaker boots are designed to protect these critical devices, extending breaker life-spans and in turn helping to ensure long-term security of the
system as a whole. Molded from APM Hexseal’s transparent silicone RUBRGLAS®, which is specially formulated to maintain clarity and prevent yellowing over time,
these boots allow for easy device operation and status recognition while maintaining APM Hexseal’s exceptional environmental
protection from weather exposure, wash downs, salt water, lubricants, solvents, dust, dirt, grease and any number of other
environmental elements that could potentially threaten electrical components. Our two distinct boot styles are
Back-of-Panel, secured behind the breaker mounting panel, and Front-of-Panel, mounted to the outside of a
panel using a sturdy metal frame. Both styles are secured using APM Hexseal’s self-sealing Seelskrews.
Much like our Circuit Breaker Boots, APM Hexseal’s Rocker Boots are often molded from transparent
silicone RUBRGLAS® which makes for easy viewing of the switch position. The majority of our Rocker Boots
do not include an insert or frame, and are designed to install on the switch prior to the switch installation.

UHF和HF都是一般的技术分类，不过每一类都有独立的支持协议。HF在13.56MHz频段更具有一致性，虽然国际业内行业标准很多。UHF RFID在858-960MHz频段已商业化。同时也有多种国际标准支持，包括EPC global Gen 2。 标签与读写器通过无线链接交换数据。链接可以通过适合任何频段的、具有不同读取范围和抗干扰性的EMF或RF场实现。HF RFID技术主要通过电磁场传送信...[详细]
控制器局部网CAN(Controller Area Network)属于现场总线的一种，是一种有效支持分布式控制或实时控制的串行通信网络，被公认为是最有前途的现场总线之一。 在工业控制系统中，电动执行器是电动单元组合仪表中一个很重要的执行单元。它由控制电路和执行机构两个在电路上完全独立的部分组成，可接收来自调节器的电控信号，将其线性地转换成机械转角或直线位移，用来操纵风门、挡板、阀门等...[详细]
据国外媒体报道，英特尔将处理器价格最高下调31%，但降价整体来说是有限的。 根据英特尔7月20日的新定价单来看，Core 2 Duo E8500(3.16GHz)价格降幅最高，从266美元下调至183美元，降幅达31%；Core 2 Duo E7200 (2.53GHz)次之，从133美元下调至113美元，降幅15%。 其他降价处理器还有四核Q6600(2.4GHz)，从224美...[详细]
