Thin, Compact, Cylindrical Photoelectric Sensor
E3HF/E3HS/E3HT/E3HC
CSM_E3HF_E3HS_E3HT_E3HC_DS_E_4_1
• Cylindrical models (E3HT and E3HC) are ideal for embedded
installation.
• Square 7.5-mm model (E3HS) has a sensing distance of 1 m.
• Resin-filled models (E3HS and E3HC) offer excellent vibration
resistance.
• Ultra-thin 7-mm model (E3HF) requires very little depth for
installation, helping to save space.
• E3HTand E3HC comply with EN standards.

* Models numbers for Through-beam Sensors (E3H@-1E@) are for sets that include both the Emitter and Receiver.
Emitter model numbers are in the form E3H@-1L (e.g., E3HF-1L). Receiver model numbers are in the form E3H@-1DE@ (e.g., E3HF-1DE1). Refer to
