Safety interlock Switches CM cm Series most Diverse and flexible line of coded magnetic Safety interlock Switches and controllers Combine door switch monitoring and E-stop monitoring by using the CM-S41 controller Monitor is single switch to CAT4 with the CM-S30 controller Monitor multiple switches to CAT3 using CM-S4 or CM-S30 controllers Monitoring multiple switches on individual channels can be achieved by using the CM-S21 or CM-S41 controllers. Easily expand your system by using the CM-SE expansion module. All CM switches are rated IP67 Stainless steel switches are available for harsh environments r C US Conforms to EN292, EN60204-1, EN954-1, EN1088, EN60947-5-3, EN947-5-3, g EN50081, EN50082, EN61000-6-2, ISO 13849-1 UL and C-UL listed, TUV certified Description The CM series of controllers and coded magnetic switches Switch categories offers the most flexibility and widest range of options available. The CM series of switches are all magnetically coded. The CM series is comprised of two basic technologies. The CM series of switches fall into three main categories: 1. 2-wire Coded Magnetic controller t echnologies 2. Conventional Read Style 1 N/C + 1 N/O contacts 3. Universal Read Style 2 N/C + 1 N/O contacts 2-Wire Single channel controllers The CM-S41 and CM-S21 controllers monitor the 2-wire The 2-wire Coded Magnetic Switches are only compatible with magnetically coded switches. The CM-S41 and CM-S21 control- the CM-S21, CM-S41 and CM-SE control units and expansion lers use a patented technology which allows them to monitor the module. The Conventional Read Style Switches are compatible 2-wire or single channel switches up to Category 3. The ability to with the CM-S4 and CM-S30 controllers. The Universal Read monitor just a single channel enables the CM-S41 and CM-S21 to Style Switches are unique in design, all three contacts are rated easily monitor multiple switches and provide individual status of for safety. This means that Universal Read Style switches can each channel. Both of these controllers are compatible with the be used with the CM-S4 or CM-S30 Controllers, or conventional CM-SE expansion module. safety monitoring relays such as the G9SA, SR103 or G9SX-AD, Dual channel controllers -BC. This allows the Universal Read Style Switches to be run in The CM-S4 and CM-S30 controllers are designed to monitor series with E-stop switches or other mechanical door switches. conventional read-style, magnetically-coded switches with 1 N/O Typically a category 2 rating would be applied to a system that + 1 N/C contacts. The CM-S4 controller can monitor up to four incorporates multiple switches wired in series to a standard safety switches to category 3. The CM-S4 controller offers status indica- monitoring relay. A risk assessment should always be performed tion for each individual switch. The CM-S30 controller can monitor by properly trained and authorized personnel. one switch to category 4, or two switches to category 3. The CM- S30 control unit is capable of monitoring up to 30 conventional read style switches in series, but does not conform to category 3 when used with more than two switches.
