|
| ||
| Normally Open Contacts | A normally open switch is a relay contact pair that is open when the coil is not energized. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Normally Closed Contacts | A normally closed switch is a relay contact pair that is closed when the coil is not energized. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Changeover Contacts | Changeover, Typically Form C (SPDT) | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Positive Break Contacts? | Also called positive opening contacts. The contact point opens reliably and remains open in activated position even in the event of mechanical failure, such as breakage of a spring or contact welding. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||

| Maximum Current | |||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Maximum AC Voltage | |||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Maximum DC Voltage | |||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||

|
|
| ||
| Sensing (Make) Range | The distance between the actuator and the sensing head to safely activate the relay outputs. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Break Range | The distance between the actuator and the sensing head to ensure relay outputs are safely deactivated. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||

|
|
| ||
| Your choices are... | |||
| Control Unit | Integral control unit for monitoring multiple switches. | ||
| Emergency Override | Locking mechanism can be overridden in emergency situations by using either a tool or an override key. | ||
| Explosion Proof | |||
| Hermetically Sealed | |||
| Magnetically Coded Actuator | Actuation by a specific (coded) magnetic field array matched to the circuit’s reed array pattern. | ||
| Manual Time Delay | Time delay is used to protect an area where the hazard remains for a time even after the machine control has been turned off. | ||
| Tamper Resistant | Protection against unauthorized adjustment or circumvention. Not easily bypassed. | ||
| Visual Indicator | Contains an integral visual indicator such as an LED. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
Environment

|
|
| ||
| Operating Temperature: | The temperature range over which the device must operate. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
