IFM E21310 is an FT-11 fibre optic diffuse reflection sensor designed for industrial sensing applications. The model designation is FT-11-EPV-Q3/F2x1/2m and it uses a straight sensing head with a 3 x 11 x 15 mm probe dimension. The fibre assembly has a total length of 2000 mm and a minimum bending radius of 2 mm. It uses PMMA fibre material with a stainless-steel 303 / 1.4305 fibre head and PE sheath. The sensor is compatible with IFM OBF, OCF and OO50 fibre-optic amplifiers.

E21310 operates using the diffuse reflection sensing principle and is intended for industrial environments. The fibre optic arrangement allows the sensing head to be positioned in locations where a conventional sensor body may be difficult to install. The sensing head detects objects through reflected optical energy and transfers the signal through the fibre assembly to a compatible amplifier. This makes the product suitable for compact and mechanically constrained sensing locations. The fibre-based construction provides flexibility for machine integration.
The sensor has a total fibre length of 2000 mm, providing substantial flexibility for routing between the sensing point and the fibre-optic amplifier. The minimum bending radius is only 2 mm, allowing the fibre to be routed through compact machine spaces. The sensing head has a straight configuration with dimensions of 3 x 11 x 15 mm. This compact head can be positioned close to the target area. The combination of a small sensing head and flexible fibre routing makes the sensor useful for confined industrial installations.
E21310 is specified for use with IFM OBF, OCF and OO50 fibre-optic amplifiers. The listed fibre-optic ranges are 70 mm with OBF, 1060 mm with OCF High Power and 150 mm with OO50. This compatibility allows the fibre head to be combined with different amplifier configurations according to the sensing requirement. The fibre material is PMMA, while the fibre head uses stainless steel 303 / 1.4305 and the sheath uses PE. Two M2 stainless-steel hexagon nuts are supplied with the sensor.
