Omron E2S DATASHEET
Miniature Square Inductive Proximity Sensor
E2S
• Miniature housing with long sensing ranges
• Front ans side facing sensing surfaces
Features
5.5 mm
The 5.5 mm x 5.5 mm type permits smaller, space-saving machines and devices.
Adopted for more compact machines and devices.
Ultra small housing
5.5mm
1 kHz
IP67
Full sealing structure housing, degree of protection IEC60529 IP67.
1/20
Significantly lower current consumption. The 0.8 mA (for 24
VDC) leakage current for the DC 2-wire type has a ratio of approximately 1/20 compared to the conventional DC 3-wire
type. Optimum solution for multiple-sensor applications such
as cam switches.
High-Speed Response
Environment-Resistant Types
Low Current Consumption (Compared to conventional models)
