- Key Products/Technologies
- SNAP-LOCK® Limit Switches: A diverse range of models including EA040 (neutral position), EA060 (short travel), EA080 (rocker type standard, neutral position), EA150 (gravity/spring return), EA700 (cam-operated), EA780-790 (Navy-Marine), and EA880 (hazardous location). These switches feature snap action, mechanical locking mechanisms, quick make/break contacts, totally sealed construction, heavy-duty contacts, corrosion-resistant, and water/dust/oil tight enclosures.SNAP-LOCK® Limit Switches: A diverse range of models including EA040 (neutral position), EA060 (short travel), EA080 (rocker type standard, neutral position), EA150 (gravity/spring return), EA700 (cam-operated), EA780-790 (Navy-Marine), and EA880 (hazardous location). These switches feature snap action, mechanical locking mechanisms, quick make/break contacts, totally sealed construction, heavy-duty contacts, corrosion-resistant, and water/dust/oil tight enclosures.
- Sensors: Proximity sensors (non-contact metallic object detection, high-speed switching, compact versions, DuraProx™ extended range, high-temperature, abrasion-resistant coating, weld field immune, internal short circuit protection for 2-wire sensors), photoelectric sensors (light-based object detection), capacitive sensors (metallic and non-metallic material detection), and inductive sensors (magnetic field disruption for metal detection). Cylindicator® sensors offer 10-30VDC, latching/non-latching SCP, 90° rotatable, low profile, C2™, LPR, and 3,000/5,000 psi specifications. Flow sensors utilize calorimetric sensing with no moving parts for monitoring coolant water or lubricant flow.Sensors: Proximity sensors (non-contact metallic object detection, high-speed switching, compact versions, DuraProx™ extended range, high-temperature, abrasion-resistant coating, weld field immune, internal short circuit protection for 2-wire sensors), photoelectric sensors (light-based object detection), capacitive sensors (metallic and non-metallic material detection), and inductive sensors (magnetic field disruption for metal detection).
