A fully monitored system that meets Category 3 when 1 to 30 plus switches are used with the CM Control Units
External Device Monitoring (EDM) with monitored manual or automatic reset
NEMA 6 switch enclosures satisfy most application requirements
Magnetically coded switches are tamper resistant to common magnets
Misalignment tolerance of (5 and 9 mm) reduces nuisance tripping
Dual channel N/C E-stop input is monitored by the CM-S41 control in addition to four CM switches
Mechanical interlock switches may be used with the CM-S4 control unit
CM control units may replace a safety relay in most applications
CM-S221 switches with 2 N/C safety contacts and 1 N/O auxiliary contact may be used with many other safety monitoring relays accepting 2 N/C safety inputs including the SR103AM; CM-S221 switches are not compatible with Legacy Relay products or the SR203M/AM, SR208AD or SR209AD

Description

    The CM switches are tamper resistant non-contact safety interlock switches that operate with their own control units except for the CM-S221 switch. The CMS221 switch will work with many safety monitoring relays accepting 2 N/C safety inputs. The CM control units will monitor one to four CM switches to category 3 in accordance with EN954-1.
    The CM-S4 controller is designed to work with with non-contact switches with dry contacts 1 N/C + 1 N/O. The CM-S21 and CMS41 controllers and the CM-SE expansion module are designed to only accept CM-S11 and CM-S31 switches. These controllers sense voltage and current changes in the switch circuit when the actuator is presented to the switch.
    The CM control units provide EDM (External Device Monitoring, also called MPCE monitoring) and an automatic reset function. This allows the CM control units to replace a safety relay in most applications.
    The NEMA 6 encapsulated design of the CM Series switch makes it ideal for harsh environments.
    Mechanical switches and CM Series switches may be used together with a single CM-S4 control unit for applications requiring both non-contact and mechanical safety interlock switches.
    The CM Series switch and actuator are available in four sizes plus a stainless steel version to accommodate a variety of application requirements.

Specifications are subject to change without notice.

Note: The safety contacts of the Omron STI switches are described as normally closed (N/C) i.e., with the guard closed, actuator in place, and the machine able to be started.
